DIAGNOSTIC HIGHLIGHTSFAITS SAILLANTS EN MATIÈRE DE DIAGNOSTIC

Carbamate insecticide toxicity in a coyote in Ontario

In December 2019, a coyote was found having a generalized (grand mal) seizure in the middle of a residential neighbourhood in Burlington, ON. After rabies infection was ruled out, the coyote was brought to us at the Canadian Wildlife Health Cooperative Ontario/Nunavut region for post-mortem examination.

Aside from the trauma associated with euthanasia, the only finding on post-mortem examination was a blue-green material throughout the stomach and intestines. There was no evidence of anticoagulants in the screen; however, LC/MS detected methomyl in the gastrointestinal tract material. Based on the amount of blue-green material in the gastrointestinal tract and the severe clinical signs noted, it is suspected this was a deliberate poisoning.

Methomyl is a carbamate insecticide, which is a broad-spectrum agent used to kill insect pests and is commonly used as a fly bait. Methomyl is highly toxic to both mammals and birds and can be quickly absorbed through the skin, lungs, and gastrointestinal tract. In acute cases, methomyl will cause central nervous symptoms (predominantly seizures) and respiratory arrest.

Intoxication à un insecticide de type carbamate chez un coyote en Ontario

Un coyote présentant des convulsions généralisées (grand mal) a été trouvé au milieu d’un quartier résidentiel, à Burlington, Ontario, en décembre 2019. Après avoir vérifié l’absence d’infection à la rage, le coyote a été transmis au Centre régional de l’Ontario/Nunavut du Réseau canadien de santé de la faune pour examen post mortem.

La présence d’un matériel bleu vert dans l’estomac et les intestins est la seule constatation de l’examen post mortem à part le traumatisme associé à l’euthanasie. Aucune trace d’anticoagulants n’a été détectée. On a toutefois détecté la présence de méthomyl (par LC/MS) dans le matériel du tractus gastro-intestinal. La quantité de matériel bleu vert trouvée dans le tractus gastro-intestinal et la sévérité des signes cliniques permettent de soupçonner un empoisonnement délibéré.

Le méthomyl est un insecticide de la famille des carbamates. On utilise cet agent à large spectre pour tuer les insectes nuisibles. On l’utilise couramment pour appâter les mouches. Le méthomyl a une toxicité élevée, à la fois chez les mammifères et les oiseaux. Il peut être rapidement absorbé par la peau, les poumons et le tractus gastro-intestinal. Dans les cas aigus, le méthomyl provoque des symptômes au niveau du système nerveux central (surtout des convulsions) ainsi qu’un arrêt respiratoire.

Surveillance de la santé du sanglier en Saskatchewan

Des membres du personnel du Centre régional de l’Ouest et du Nord du RCSF ont participé à l’abattage de sangliers au cours de l’hiver dernier. Ils ont examiné 15 sangliers et prélevé des spécimens en vue de procéder à des tests relatifs à certaines maladies d’intérêt. Les tests sont en train d’être effectués.

 

Est-ce que les programmes de contrôle des rats réduisent les risques en matière de santé publique?

Dans le cadre du programme VRP, on a mené une campagne expérimentale de contrôle des animaux nuisibles, à l’aide de pièges, à Vancouver. Les rats qui n’ont pas été capturés avaient plus tendance à être porteurs de maladies dangereuses que ceux qui avaient été examinés avant cette campagne.

FEATURED PROJECTPROJET VEDETTE

Toxoplasma gondii: a cat parasite in St. Lawrence beluga whales

In a scientific article published last fall in the journal Diseases of Aquatic Organisms, researchers report the detection of Toxoplasma gondii DNA in the tissues of 44% of the beluga carcasses tested.1 The samples used in this study were obtained from the St. Lawrence belugas mortality surveillance program managed by the CWHC-Quebec Regional Center. Males had a higher infection rate than females and this parasite was more frequent in calves and juveniles compared to adults.

 Of the 15 animals in which T. gondii was detected in the study cited here,1 infection by T. gondii was determined to be the cause of death in only one animal. The other cases were either asymptomatic infections or significant infections but that could not be detected at post-mortem examination. This project demonstrates that the St. Lawrence beluga is highly exposed to a parasite that can potentially be pathogenic. Since the beginning of the St. Lawrence beluga mortality monitoring program in 1983, we have documented seven cases of beluga strandings caused by fatal T. gondii infections, which represents 4% of strandings for which the cause of death has been determined. Although this number seems small, it is undoubtedly an underestimation of the actual number of mortalities associated with this parasite in this population. Furthermore, it is well known that T. gondii can also cause sub-clinical (non-lethal) effects in intermediate hosts, such as behavioral changes, which may also contribute to diminishing the animals ability to survive and to reproduce. Therefore, although the impact of this parasite on St. Lawrence belugas is difficult to assess, its presence certainly does not help the recovery of this threatened population.

 Toxoplasma gondii is unlikely to be a newcomer to the beluga ecosystem; before the arrival of the Europeans in America, it was probably already established in lynx. On the other hand, it is reasonable to assume that the arrival of domestic cats in North America has contributed to significantly increase the density of cysts of this parasite in the environment and therefore increasing the "infection pressure" on belugas. In addition, the exposure of belugas to high levels of contaminants known to have negative effects on the immune system (such as PCBs) may also reduce the natural resistance of beluga whales to this parasite and thus favor fatal infections. The reduction of PCBs levels in the environment is therefore good news for this cetacean population and should help improve their ability to cope with pathogens such as T. gondii. On the other hand, as these contaminants are extremely resistant, this improvement will spread over several decades. The best way to reduce the contamination of the environment by this parasite remains the responsible care of domestic cats. By having access to the outside environment without supervision, cats increase their risk of being infected by hunting and eating rodents and birds potentially carrying T. gondii cysts. By defecating outside, they will contribute to increase the density of this parasite in the environment and therefore the risks for potentially sensitive species such as beluga whales. Toxoplasma gondii cysts are extremely resistant and can survive in runoff to reach beluga habitat. A cat kept inside and allowed to go outside with supervision will have no risk of catching this parasite and will therefore not contribute to the problem. In addition, its well-being and life expectancy will be greatly improved. Similarly, because of their potential impact on wildlife or because of animal welfare issues (for cats), it is not recommended to support feral cat colonies.

Toxoplasma gondii : un parasite des chats chez les bélugas du Saint-Laurent

Dans un article scientifique publié l’automne dernier dans la revue Diseases of Aquatic Organisms, des chercheurs ont rapporté la détection de l’ADN de Toxoplasma gondii dans les tissus de 44 % des carcasses de béluga testées.1 Les spécimens utilisés dans le cadre de cette étude provenaient du Programme de surveillance de la mortalité des bélugas du Saint-Laurent qui est géré par le Centre régional du Québec du RCSF. Un taux d’infection plus élevé a été observé chez les animaux mâles que chez les femelles. On a aussi constaté une fréquence plus élevée du parasite chez les baleineaux et les animaux juvéniles que chez les adultes.

Dans le cadre de l’étude citée plus haut,1 l’infection à T. gondii a été reconnue comme cause de la mort chez un seul animal parmi les 15 animaux porteurs du parasite. Dans les autres cas, il s’agissait d’infections asymptomatiques ou significatives. Il a toutefois été impossible d’identifier celles-ci lors de l’examen post mortem. Cette étude a révélé une exposition élevée à un parasite potentiellement pathogène chez les bélugas du Saint-Laurent. Depuis le début du programme de surveillance de la mortalité des bélugas du Saint-Laurent, en 1983, sept cas d’échouage de bélugas causés par des infections fatales à T. gondii ont été documentés par le RCSF du Québec, ce qui représente 4 % des bélugas échoués dont la cause de la mort a été déterminée. Bien que ce pourcentage puisse sembler faible, il s’agit sans doute d’une sous-estimation du nombre de mortalités associées au parasite chez cette population. Par ailleurs, il est reconnu que T. gondii peut aussi avoir des effets subcliniques (non létaux), comme des changements de comportement, chez les hôtes intermédiaires, ce qui peut réduire leur capacité de survie et de reproduction. Bien que l’impact du parasite T. gondi sur les bélugas du Saint-Laurent soit difficile à évaluer, la présence de ce parasite ne favorise certainement pas le rétablissement de cette population menacée.

DIAGNOSTIC HIGHLIGHTSFAITS SAILLANTS EN MATIÈRE DE DIAGNOSTIC

Ophidiomycosis (snake fungal disease) confirmed as the cause of death for two Massasauga rattlesnakes in Ontario

In October 2018, two Massasauga rattlesnakes were found to be suffering from numerous facial/oral swellings and ulcers. Infection with Ophidiomyces ophiodiicola was confirmed by polymerase chain reaction (PCR) from skin swabs from affected regions. The snakes failed to respond to therapy and both died in mid-November 2018. On post-mortem examination, both snakes had extensive ulcerative lesions over the face and extending into the oral cavity. Fungal hyphae were noted to be invading throughout the soft tissue of the head including into the nasal and oral cavities, the brain in one snake, and into the lung parenchyma in both snakes.

Ophidiomycosis (snake fungal disease) is caused by the fungus Ophidiomyces ophiodiicola and the earliest known case in Ontario was from a sample submitted in 2012 (which was tested in 2016 when the PCR became available).  The disease has been increasing in prevalence across multiple states and provinces over recent years. Infection with O. ophiodiicola has been detected with frequency in snakes in Ontario (18.2% of snake samples received by the CWHC have tested positive by PCR from skin swabs or biopsies of lesions). Although O. ophiodiicola has been implicated in the deaths of snakes in other regions, it has never been implicated as the proximal cause of death in snakes in Ontario.

Confirmation de l’ophidiomycose (maladie fongique du serpent) comme cause de mortalité chez deux massasaugas en Ontario

On a retrouvé deux massasaugas présentant de nombreux ulcères faciaux ou oraux et de l’œdème facial en octobre 2018. L’infection à Ophidiomyces ophiodiicola a été confirmée par réaction en chaîne par polymérase (PCR) effectuée sur des échantillons de peau prélevés sur les régions affectées. Le traitement s’étant révélé inefficace, ces deux serpents ont succombé à la mi-novembre 2018. L’examen post mortem a révélé d’importantes lésions ulcéreuses sur la face chez les deux serpents; celles-ci s’étendaient jusqu’à la cavité orale. On a aussi observé une invasion des tissus mous de la tête par des hyphes fongiques, entre autres dans les cavités nasale et orale, dans le cerveau chez l’un des serpents et dans le parenchyme pulmonaire chez les deux serpents.

L’ophidiomycose (maladie fongique du serpent) est causée par le fongus Ophidiomyces ophiodiicola. Le premier cas a été observé en Ontario à partir d’un spécimen soumis en 2012 (qui a été testé en 2016 lorsque le PCR est devenu disponible). La prévalence de la maladie a augmenté dans de nombreux états et provinces au cours des dernières années. L’infection à O. ophiodiicola a été détectée fréquemment chez des serpents en Ontario (les tests par PCR effectués sur des spécimens reçus par le RCSF (écouvillons de peau ou biopsies des lésions) se sont révélés positifs dans 18,2 % des cas. Bien que O. ophiodiicola ait déjà été responsable de la mortalité de serpents dans d’autres régions, il n’avait jamais été identifié en tant que cause proximale de mortalité chez des serpents en Ontario.

Chronic Wasting Disease in Saskatchewan and Quebec

During the fall hunting season in Saskatchewan, over 2000 deer, elk and moose were tested for Chronic Wasting Disease (CWD). In total, 299 (14%) animals tested positive, including deer hunted in wildlife management areas where the disease was not previously known. More information about CWD in Saskatchewan and specifically about the 2018 results are available on the CWHC website: http://www.cwhc-rcsf.ca/cwd.php

In September, CWD was detected in a farmed deer in Quebec. During the investigation, an additional 10 infected animals were detected, all from the same property. The investigation to determine how CWD was introduced to the farm is ongoing.

Wild deer and elk from the surrounding area were culled or hunted; a total of 1798 animals were tested and all were negative suggesting that the disease is not well established in the area (https://mffp.gouv.qc.ca/la-faune/securite-sante-maladies/maladie-debilitante-chronique-cervides/ and https://www.mapaq.gouv.qc.ca/fr/Productions/santeanimale/maladies/soussurveillance/MDC/Pages/maladiedebilitante.aspx).

 

Avian influenza in 2018

Over 1000 birds found dead from across Canada were tested for Avian Influenza virus in 2018. Among these cases, the virus was detected in 18 birds but was not associated with disease in any of the animals. Live bird testing took place in BC and Saskatchewan in 2018. In these 2 provinces, 728 birds were tested, and the virus was detected in 38 birds. More detail about the AIV surveillance results is available at: http://www.cwhc-rcsf.ca/surveillance_data_aiv.php

 

Brain worm diagnosed in Cape Breton Highlands National Park

In November, the CWHC Atlantic Region diagnosed “parelaphostrongylosis”, commonly referred to as “brain worm” in a bull moose from Cape Breton Highlands National Park. Parelaphostrongylosis has been reported from Cape Breton before but is more common in moose from mainland Nova Scotia, where it has been implicated as a factor in the decline of the mainland moose population.

Mange in red foxes on Prince Edward Island

Since late 2017, mange has been affecting foxes living in and around Charlottetown, PEI. Mange is caused by a mite, Sarcoptes scabiei, that infests the skin of many species including red foxes, coyotes, wolves and domestic dogs. Mange is fairly common in wild canids on the mainland, but to our knowledge, this is the first outbreak of mange in red foxes on PEI. Prior to this, a single case of fox mange occurred in 2016, and a small number of mange cases were confirmed in PEI coyotes in the early 1990s. The CWHC is working closely with PEI Fish and Wildlife and the PEI Trappers' Association to collect samples to determine the geographic distribution of the parasite, track whether disease is spreading outside the Charlottetown area, and to identify possible risk factors for disease.

Maladie débilitante chronique en Saskatchewan et au Québec

Plus de 2000 cerfs, wapitis et orignaux ont été soumis au test de la maladie débilitante chronique (CWD) au cours de la saison de chasse de l’automne dernier en Saskatchewan. Les tests se sont révélés positifs chez 299 (14 %) animaux au total. Parmi ces animaux, on retrouvait des cerfs qui avaient été chassés dans des zones de gestion de la faune où la maladie n’avait pas encore été détectée. On retrouve des renseignements complémentaires sur la CWD en Saskatchewan, plus spécifiquement sur les résultats des tests effectués en 2018, sur le site web du RCSF à l’adresse : http://www.cwhc-rcsf.ca/cwd.php

La maladie débilitante chronique a été détectée en septembre 2018 chez un cerf d’élevage au Québec. La maladie a aussi été détectée chez 10 autres animaux de la même ferme. L’enquête se poursuit en vue de déterminer le mode d’introduction de la CWD sur cette ferme.

Les cerfs et wapitis sauvages de la région environnante ont été abattus ou chassés. Des tests ont été effectués sur 1798 animaux au total. Tous les tests se sont révélés négatifs, ce qui laisse supposer que la maladie n’est pas bien établie dans la zone en question (https://mffp.gouv.qc.ca/la-faune/securite-sante-maladies/maladie-debilitante-chronique-cervides/ et https://www.mapaq.gouv.qc.ca/fr/Productions/santeanimale/maladies/soussurveillance/MDC/Pages/maladiedebilitante.aspx).

 

Influenza aviaire en 2018

Des tests de détection de l’influenza aviaire ont été effectués sur plus de 1000 oiseaux retrouvés morts dans l’ensemble du Canada en 2018. Le virus a été détecté chez 18 de ces oiseaux; celui-ci n’a toutefois pas été associé à la maladie chez ces oiseaux. Par ailleurs, des tests ont été effectués sur 728 oiseaux vivants provenant de la CB et de la Saskatchewan en 2018. Le virus a été détecté chez 38 oiseaux. On retrouve des renseignements complémentaires sur les résultats de la surveillance de l’influenza aviaire à l’adresse : http://www.cwhc-rcsf.ca/surveillance_data_aiv.php.

 

Ver des méninges diagnostiqué au Parc national des Hautes-Terres-du-Cap-Breton

Le Centre régional de l’Atlantique du RCSF a diagnostiqué la « parélaphostrongylose », appelée communément « ver des méninges », chez un orignal mâle au Parc national des Hautes-Terres-du-Cap-Breton en novembre 2018. La parélaphostrongylose a déjà été rapportée au Cap Breton, mais on l’observe plus souvent en Nouvelle-Écosse continentale. Cette maladie est l’un des facteurs responsables du déclin de la population d’orignaux en Nouvelle-Écosse continentale.

Gale chez des renards roux de l’Île-du-Prince-Édouard

Depuis la fin de 2017, la gale affecte les renards à Charlottetown, ÎPÉ, et dans les environs. La gale ou scabiose est causée par l’acarien parasite Sarcoptes scabiei. Celui-ci infecte la peau de nombreuses espèces, entre autres le renard roux, le coyote, le loup et les chiens domestiques. Bien qu’on observe couramment la gale chez les canidés sauvages sur le continent, il s’agit de la première épidémie chez le renard roux, à notre connaissance, à l’ÎPÉ. Un seul cas de gale avait été détecté chez le renard avant cet incident, à savoir en 2016. Un faible nombre de cas ont aussi été confirmés chez des coyotes de l’ÎPÉ au début des années 1990. Le RCSF collabore étroitement avec le ministère de la Pêche et de la Faune et l’Association des trappeurs de l’ÎPÉ en ce qui a trait à la collecte de spécimens pour être en mesure de déterminer la distribution géographique du parasite, de vérifier si la maladie est en train de se propager hors de la région de Charlottetown et d’identifier les facteurs de risque potentiels de la maladie.

Health of muskoxen in Nunavik, Quebec

Muskox is an iconic species for the Arctic ecosystem and for the Inuit culture. Several populations of muskoxen are declining in Canada. The Nunavik muskoxen population in Northern Quebec is the result of the introduction of approximately fifty animal issued from Ellesmere Island. The impact of this introduction on the Nunavik ecosystem is the subject of a study undertaken by Caribou Ungava and by the Ministère des Forêts, de la Faune et des Parcs. As part of this study, muskoxen were equipped with satellite collars to track their movements. The CWHC-Quebec team conducted a health assessment of the animals captured. The muskoxen examined seemed healthy; the very high pregnancy rate (94%) and the presence of several calves in the groups observed are indicators of good reproductive successes. Interestingly, serologic testing did not detect evidence of exposure to Brucella sp. and Coxiella burnetii, two pathogens reported in other muskoxen populations. On the other hand, blood tests suggest that 41% of the examined animals had been exposed to Erysipelothrix rhusiopathiae, a bacteria that has recently been implicated in mortality of muskoxen in Nunavut. In addition, antibodies against Besnoitia sp., a protozoan affecting the skin, and eggs of the great liver fluke (Fascioloides magna) were present in about half of the animals. Muskoxen are most likely "spill over hosts" for these two parasites, which are very common among caribou sharing this ecosystem. The health assessment conducted during this project does not suggest that the introduction of muskoxen represent a health risk for Nunavik migratory caribou populations.

État de santé des bœufs musqués au Nunavik, Québec

Le bœuf musqué est une espèce iconique pour l'écosystème arctique et la culture Inuite. Plusieurs populations de bœufs musqués connaissent un déclin au Canada. La population de bœufs musqués du Nunavik, au Nord-du-Québec, est issue de l'introduction d'une cinquantaine de sujets provenant de l'Île d'Ellesmere. L'impact de cette introduction sur l'écosystème du Nunavik est le sujet d'une étude entreprise par Caribou Ungava et par le Ministère des Forêts, de la Faune et des Parcs. Dans le cadre de cette étude, des bœufs musqués ont été munis de colliers satellitaires afin de suivre leurs déplacements. L'équipe du RCSF-Québec a effectué une évaluation de l'état de santé des animaux capturés. Les bœufs musqués examinés semblaient en très bonne santé; le pourcentage très élevé de femelles gravides (94%) et la présence de plusieurs veaux dans les groupes observés sont des indicateurs d'un bon succès reproducteur. Fait intéressant, les analyses sérologiques n'ont pas détecté d'évidence d'exposition à Brucella sp. et à Coxiella burnetii, deux agents pathogènes rapportés chez d'autres populations de bœufs musqués. Les examens sanguins suggèrent par contre que 41% des sujets ont été exposés à Erysipelothrix rhusiopathiae, une bactérie qui a récemment été impliquée dans des mortalités chez des bœufs musqués du Nunavut. De plus, des anticorps contre Besnoitia sp., un protozoaire affectant la peau, et des œufs de la grande douve du foie (Fascioloides magna) étaient présents chez environ la moitié des animaux. Le bœuf musqué serait en fait un "hôte de débordement" pour ces deux parasites qui se retrouvent très fréquemment chez les caribous partageant cet écosystème. Les examens fait au cours de ce projet ne suggèrent pas que l'introduction de bœufs musqués a représenté un risque sanitaire pour les populations de caribous migrateurs du Nunavik.

DIAGNOSTIC HIGHLIGHTSFAITS SAILLANTS EN MATIÈRE DE DIAGNOSTIC

Ranaviruses infect cold-blooded vertebrates, including amphibians and reptiles.

Ranavirus infection was recently confirmed as the cause of death in a Snapping Turtle, a Wood Turtle and 2 Painted Turtles that were examined at the CWHC Ontario/Nunavut Regional Centre. Ranavirus infection has been implicated in die-offs of amphibians in many locations, including Ontario, but this was the first time the virus has been confirmed as the cause of death in Ontario turtles. Tissues from both turtles were tested at the British Columbia Animal Health Centre in Abbotsford using real-time polymerase chain reaction (rtPCR). 

A mass mortality event involving wood frogs and spotted salamanders in a pond near Quebec City was reported in early July. An adult frog and some salamander larvae were submitted to the CWHC – Quebec Regional Centre for examination and Ranavirus was confirmed by PCR at the British Columbia Animal Health Centre. Although Ranavirus has been documented in Quebec before, this is the first report of the virus causing disease in amphibians in the province.

Reports of outbreaks caused by Ranavirus appear to be increasing in frequency but its occurrence and range in the wild are not well understood. It has been suggested that these viruses may be contributing to the decline of several amphibian populations. The recent detection of Ranavirus in Ontario turtles further raises the concern about the effect of these viruses on amphibian and reptilian populations. Many turtle species in Ontario are classified as Species at Risk.

Les ranavirus infectent les vertébrés à sang froid, entre autres les amphibiens et les reptiles.

Une infection au ranavirus a récemment été confirmée en tant que cause de la mort chez une tortue serpentine, une tortue des bois et 2 tortues peintes examinées au Centre régional de l’Ontario/Nunavut du RCSF. Bien que l’infection au ranavirus ait déjà été responsable de mortalités massives d’amphibiens en de nombreux endroits, y compris en Ontario, il s’agissait de la première confirmation de la présence du virus en tant que cause de mortalité chez des tortues en Ontario. Des tissus provenant des deux tortues ont été soumis à des tests de réaction en chaîne par polymérase en temps réel (rtPCR) au British Columbia Animal Health Centre situé à Abbotsford.

On a rapporté une mortalité massive de tortues des bois et de salamandres maculées dans un étang situé près de la ville de Québec au début de juillet dernier. Une grenouille adulte et quelques larves de salamandre ont été soumises pour examen au Centre régional du Québec du RCSF. Le ranavirus a été confirmé par PCR au British Columbia Animal Health Centre. Bien que la présence du ranavirus ait été documentée antérieurement au Québec, il s’agit du premier cas rapporté de maladie causée par ce virus chez des amphibiens dans cette province.

Les rapports d’épidémies dues au ranavirus semblent de plus en plus fréquents. On ne connaît pas vraiment l’occurrence et la distribution de ce virus chez les espèces sauvages. Il a été suggéré que les ranavirus pourraient contribuer au déclin de plusieurs populations d’amphibiens. La détection récente de ranavirus chez des tortues en Ontario soulève de nouvelles préoccupations quant à l’effet de ces virus sur les populations d’amphibiens et de reptiles. De nombreuses espèces de tortues de l’Ontario sont classifiées en tant qu’espèces en péril.

 


WILDLIFE HEALTH TRACKERSUIVI DE LA SANTÉ DE LA FAUNE

Chronic Wasting Disease identified in Quebec

In September, CWD was detected in a farmed deer in Quebec. An investigation is ongoing to try and determine how the animal became infected and whether or not the disease is present in wild deer in Quebec.

 

West Nile Virus detected from coast to coast

West Nile virus was detected in wild birds in Prince Edward Island in September. This is the first time that WNV has been detected in birds in the province. For the first time since 2003, birds in New Brunswick and Nova Scotia have also been confirmed with WNV infection. Birds infected with WNV, have also been detected in BC, Alberta, Saskatchewan, Manitoba, Ontario and Quebec.

 

Newcastle Disease in Ontario, Nova Scotia and Prince Edward Island

Newcastle disease is caused by a virus that regularly infects Double-crested Cormorants at the end of the nesting season. Infection with the virus causes damage to the central nervous system. Since August, the virus has been detected in sick and dead cormorants from Ontario, Nova Scotia and Prince Edward Island.

 

White-nose Syndrome continues to spread

Epizootic hemorrhagic disease, the highly fatal disease of deer, has been confirmed in Ontario for the first time.

 

Identification de la maladie débilitante chronique (CWD) au Québec

La CWD a été détectée en septembre dernier chez un cerf d’élevage au Québec. Une enquête est en cours pour essayer de déterminer le mode d’infection de l’animal et vérifier la présence de la maladie chez les cerfs sauvages au Québec.

 

Détection du virus du Nil occidental (VNO) d’un océan à l’autre

Le virus du Nil occidental a été détecté chez des oiseaux sauvages de l’Île-du-Prince-Édouard en septembre dernier. Il s’agissait de la première détection du VNO dans cette province. Une infection au VNO a également été confirmée pour la première fois depuis 2003 chez des oiseaux au Nouveau-Brunswick et en Nouvelle-Écosse. On a aussi retrouvé des oiseaux infectés par le VNO en CB, en Alberta, en Saskatchewan, au Manitoba, en Ontario et au Québec.

 

Maladie de Newcastle en Ontario, en Nouvelle-Écosse et à l’Île-du-Prince-Édouard

La maladie de Newcastle est causée par un virus qui infecte régulièrement les cormorans à aigrettes vers la fin de la saison de nidification. Une telle infection provoque des lésions au système nerveux central. Depuis le mois d’août, le virus a été détecté chez des cormorans morts ou malades en Ontario, en Nouvelle-Écosse et à l’Île-du-Prince-Édouard.

 

Le syndrome du museau blanc continue de se propager

L’infection par le fungus responsable du syndrome du museau blanc a tué des millions de chauves-souris en Amérique du Nord depuis sa détection originale en 2006. Le fungus a continué de se propager vers de nouvelles régions en 2018. Il a été identifié pour la première fois au Manitoba, au Dakota du Sud, au Wyoming, au Kansas et au Nouveau-Mexique.


FEATURED PROJECTPROJET VEDETTE

Canada now has a national plan for wildlife health.

On June 28th, Canada’s federal, provincial, and territorial Ministers responsible for Parks, Protected Areas, Conservation, Wildlife and Biodiversity approved A Pan-Canadian Approach to Wildlife Health.

The Pan-Canadian Approach outlines a shared vision for wildlife health in Canada, identifies challenges and opportunities and recommends priority actions to protect and promote wildlife health and the values it brings to Canadians. Four goals are identified in the plan: 1) to strengthen Canada’s capacity to identify and reduce wildlife health threats, 2) to develop, implement and assess programs and policies to increase equity in wildlife health capacity across the country, 3) to support wildlife managers through research, policy and planning to better enable wildlife to cope with change, and 4) to improve efficiency and effectiveness of programs.

The plan took over 4 years to develop and together with the leadership of Environment and Climate Change Canada, the CWHC played an instrumental role crafting and realizing the final product.

The next step is to get agreement on actions to implement the plan. The essential structures and plans necessary to implement A Pan-Canadian Approach to Wildlife Health are already in place. The CWHC and its supporting network of wildlife health professionals with expertise in wildlife health and experience collaborating with government on various wildlife health programs and activities will play a central implementation role.

More information about the plan and its approval can be found at: http://www.scics.ca/en/product-produit/news-release-parks-protected-areas-conservation-wildlife-and-biodiversity-key-priorities-for-federal-provincial-territorial-ministers/

Le Canada dispose maintenant d’un plan national de santé de la faune.

Le 28 juin dernier, les ministres responsables de la conservation, des parcs, des aires protégées, de la faune et de la biodiversité à l’échelon fédéral, provincial et territorial ont endossé une Approche pancanadienne en santé de la faune au Canada.

Cette approche pancanadienne s’appuie sur une vision commune de la santé de la faune au Canada. Elle identifie les obstacles à surmonter et les occasions à saisir tout en recommandant les actions à entreprendre en priorité pour protéger la santé des animaux sauvages et la valeur qu’ils représentent pour les Canadiens. Ce plan identifie quatre objectifs : 1) renforcer la capacité du Canada en matière d’identification et de réduction des menaces en santé de la faune, 2) développer, mettre en œuvre et évaluer des programmes et politiques visant à améliorer la capacité en santé de la faune dans l’ensemble du pays, 3) appuyer les gestionnaires de la faune par la recherche, les politiques et la planification pour permettre aux espèces sauvages de mieux s’adapter aux changements, 4) améliorer l’efficience et l’efficacité des programmes.

L’élaboration de ce plan a nécessité plus de 4 années. Environnement et Changements climatiques Canada en a assuré le leadership. Le RCSF a joué un rôle crucial au niveau de la conception et de la réalisation du produit final.

La prochaine étape consiste à se mettre d’accord sur les actions entourant la mise en œuvre de ce plan. Les structures et plans essentiels à la mise en œuvre de l’Approche pancanadienne en santé de la faune au Canada sont déjà en place. Le RCSF jouera un rôle central à cet égard. Il sera appuyé par son réseau de professionnels qui disposent de l’expertise nécessaire en santé de la faune. Ceux-ci ont déjà collaboré avec le gouvernement dans le cadre de divers programmes et activités connexes en santé de la faune.

DIAGNOSTIC HIGHLIGHTSFAITS SAILLANTS EN MATIÈRE DE DIAGNOSTIC

Rabbit Hemorrhagic Disease in British Columbia

In mid-February 2018 feral rabbits were found dead in small numbers on a university campus in Nanaimo and all the rabbits in a small feral colony on Annacis Island in Delta were found dead. Necropsy examination of these rabbits revealed lesions typical of Rabbit Hemorrhagic Disease (RHD). This diagnosis was confirmed through additional testing by the CWHC and CFIA.

Rabbit hemorrhagic disease is an extremely contagious viral disease of domesticated and wild European rabbits with a mortality rate that often reaches 100% in unvaccinated European rabbits. It can be readily transmitted by direct contact with live or dead animals, and on fomites. Since the initial diagnosis there have been reports of large numbers of dead feral rabbits around Nanaimo and a few in the lower mainland.

This is the third confirmed diagnosis of Rabbit Hemorrhagic disease in Canada, the first in BC, and by far the largest reported outbreak of RHD in North America. It is the first outbreak to involve this particular strain (RHDV2) in North America.

You can read more about these outbreaks in our recent blog article:

Maladie hémorragique du lapin en Colombie-Britannique

À la mi-février 2018, on a retrouvé un faible nombre de lapins sauvages morts sur un campus universitaire à Nanaimo. On a aussi constaté la mort de tous les lapins sauvages d’une petite colonie d’Annacis Island (Delta). Les nécropsies ont révélé des lésions typiques de la maladie hémorragique du lapin (RHD). Ce diagnostic a été confirmé par des tests additionnels effectués par le RCSF et l’ACIA.

La maladie hémorragique du lapin est une maladie virale extrêmement contagieuse qui affecte les lapins de garenne domestiques et sauvages. Le taux de mortalité atteint souvent 100 % chez les lapins non vaccinés. Cette maladie peut être transmise rapidement par contact direct avec des animaux morts ou vivants ou des vecteurs passifs (objets contaminés). Un grand nombre de lapins sauvages ont été retrouvés morts dans les environs de Nanaimo depuis le diagnostic initial. On a aussi retrouvé quelques lapins sauvages morts dans le Lower Mainland.

Il s’agit de la troisième épidémie confirmée de maladie hémorragique du lapin au Canada et de la première épidémie observée en CB. Cette épidémie de RHD est de loin la plus importante rapportée en Amérique du Nord. Il s’agit de la première manifestation de cette souche particulière du virus (RHDV2) en Amérique du Nord.

FEATURED PROJECTPROJET VEDETTE

CWHC Quebec collaborates on a moose research project

A team from the Ministère des Forêts, de la Faune et des Parcs (MFFP) undertook a project to understand the effects of commercial logging on moose. Benjamin Lamglait and Stéphane Lair of the CWHC – Quebec were invited to participate to the project as veterinarians to assist with the anesthesia and the health assessment of the captured animals.

Captured adult females were equipped with radio-collars and morphometrics were measured. Tracking of animals with collars will allow the scientists to better understand the ecology and the behavior of these large mammals in the North of Quebec and assess the effects of forestry practices. The moose examined appeared to be in good physical condition and were often accompanied by a fawn. One of the observations of interest was the presence of infestations in the majority of moose by winter ticks.

The winter tick primarily attacks moose and feed repeatedly on the same moose through the winter. When heavily parasitized (tens of thousands of ticks), moose are can be weakened through significant blood loss caused by repeated tick feeding. The most noticeable clinical sign is hair loss, resulting from rubbing and scratching by moose to alleviate the itching caused by tick bites. The additional energy expenditure associated with excessive scratching and damaged fur coat, which leads to heat loss, is also responsible to the loss of moose condition. All of these signs can potentially weaken the animal until death, especially in calves.

You can read more about this project in our recent blog article (available in both English and French):

Le centre régional du Québec collabore à un projet de recherche sur les orignaux

Une équipe du Ministère des Forêts, de la Faune et des Parcs (MFFP) a entrepris un projet visant à comprendre les effets de l’exploitation commerciale des orignaux. Les vétérinaires Benjamin Lamglait et Stéphane Lair du RCSF – Québec ont été invités à contribuer ce projet en ce qui a trait à l’anesthésie et à l’évaluation de la santé des animaux capturés.

Les paramètres morphométriques ont été mesurés chez les femelles adultes équipées de colliers radio-émetteurs qui ont été capturées. Le suivi des animaux munis de colliers émetteurs permettra aux scientifiques de mieux comprendre l’écologie et le comportement de ces grands mammifères au Nord du Québec et aussi d’évaluer les effets des pratiques forestières. Les orignaux examinés semblaient en bonne condition physique. Ils étaient souvent accompagnés d’un faon. L’une des observations intéressantes réside dans la présence d’infestations par des tiques d’hiver chez la majorité des orignaux.

La tique d’hiver attaque prioritairement les orignaux ; elle se nourrit à répétition sur le même orignal tout au long de l’hiver. En cas d’infestation parasitaire importante (par des dizaines de milliers de tiques), les orignaux peuvent être affaiblis par la perte de sang significative due aux attaques répétées des tiques. Le signe clinique le plus notoire est une perte de pelage résultant des frottements et du grattage visant à soulager les démangeaisons causées par les morsures de tiques. Un grattage excessif endommage la couche de fourrure de l’animal, causant ainsi une perte de chaleur. Celle-ci entraîne une dépense additionnelle d’énergie pouvant être responsable de la détérioration de la condition physique des orignaux. Tous ces facteurs peuvent affaiblir les animaux et même entraîner la mort, surtout chez les plus jeunes animaux.

DIAGNOSTIC HIGHLIGHTSFAITS SAILLANTS EN MATIÈRE DE DIAGNOSTIC

Epidemic of Mycoplasmosis in Wild Passerines in Quebec

In February CWHC-Quebec received numerous reports and photographs of sick birds from birdwatchers in southern Quebec. These documents suggested that these birds were infected with Mycoplasmosa gallisepticum, which is the pathogen responsible for causing mycoplasmosis, also known as finch eye disease. House finches represent the most commonly affected species.

The disease often causes swelling of the eyelids, redness of the eyes, secretions and crusting around the eyes potentially sealing them shut. The disease can also cause sneezing and difficulty breathing. Though the disease is not typically directly fatal, the temporary blindness it causes can result in difficulty feeding and starvation, and increased risk of predation and/or other traumatic injuries.

The diagnosis of mycoplasmois was quickly confirmed through necropsies and PCR testing conducted by CWHC-Quebec. This confirmed the presence of an epidemic of mycoplasmosis in the birds frequenting feeders in southern Quebec. As of late February over a dozen incidents of birds exhibiting signs of the disease had been reported in the region.

You can read more about this case in our recent blog article and you can follow reported incidents of the disease in our new mycoplasmosis surveillance map:

Épidémie de mycoplasmose chez les passereaux sauvages au Québc

En février dernier, le RCSF-Québec a reçu de nombreuses mentions et photographies d'oiseaux malades de la part d'observateurs d'oiseaux du sud du Québec. Ces mentions suggèrent que ces oiseaux étaient infectés par Mycoplasma gallisepticum (agent de la mycoplasmose, également connue sous le nom de finch eye disease). Le roselin familier représente l'espèce la plus fréquemment touchée.

La maladie provoque un gonflement des paupières et une rougeur des yeux. Dans plusieurs cas la présence de sécrétions et de croûtes bloque complètement l'ouverture des yeux. La maladie peut également causer de la toux et des difficultés à respirer. Bien que la maladie ne cause pas directement la mort, la cécité qu'elle entraîne peut provoquer des difficultés d'alimentation, ainsi qu'un risque accru de prédation et / ou d'autres traumatismes.

Le diagnostic de mycoplasmose a été rapidement confirmé par des nécropsies et des tests de PCR effectués par le CWHC-Québec. À la fin de février, plus d'une douzaine d'épisodes d'oiseaux présentant des signes de la maladie avaient été signalés dans la région.

Pour plus d'information sur cette condition, consulter l'article récent sur le sujet, ainsi que la carte de surveillance de la mycoplasmose :

Transmission of disease between wildlife and livestock can significantly impact efforts to protect wildlife populations and maintain food safety. This interaction may circumvent population health programs by transmitting and reintroducing pathogens among naïve or previously uninfected populations.

Sheep producers have largely relied upon drugs to protect their livestock from the harmful parasite Haemonchus contortus, which is now exhibiting resistance to these treatments. This introduces the potential for these drug resistant parasites to be transmitted to wild deer populations and subsequently to disjunct sheep farms. Such transmission pathways of a drug resistant parasite would undermine efforts to maintain flock health and food safety.

CWHC-Alberta’s Dr. Susan Kutz and Collin Letain have recently been collecting and testing wild deer feces as part of a major research project into the role that wild deer play in spreading the parasite among sheep farms in Alberta. Currently, parasite species present in fecal samples are being identified, parasite loads are being assessed, and any H. contortus identified will be tested for drug resistance.

Transmission de maladies entre la faune et le bétail

La transmission de maladies entre la faune et le bétail peut avoir des répercussions importantes sur les efforts visant à protéger les populations d'animaux sauvages et à maintenir la salubrité des aliments. Cette interaction peut contourner les programmes de santé de la population en transmettant et en réintroduisant des pathogènes chez des populations naïves ou non infectées.

Les producteurs de moutons ont contrôlé un parasite pathogène Haemonchus contortus, à l'aide de médicaments. Ce parasite a maintenant développé une résistance à ces médicaments. Il y a donc aujourd'hui un risque de transmission de ces parasites résistants aux médicaments vers les populations de cerfs sauvages et par la suite aux élevages ovins partageant des pâturages avec les cerfs. De telles voies de transmission d'un parasite résistant aux médicaments compromettraient les efforts visant à maintenir la santé du troupeau et la sécurité sanitaire des aliments.

La Dre Susan Kutz et Collin Letain du RCSF-Alberta ont récemment recueilli et testé des fèces de cerfs sauvages dans le cadre d'un important projet de recherche sur le rôle joué par les cerfs sauvages dans la propagation du parasite dans les élevages de moutons en Alberta. Les espèces de parasites présentes dans les échantillons fécaux sont en cours d'identification. Les charges parasitaires sont évaluées, et tout H. contortus identifié sera testé pour la résistance aux médicaments. Pour plus d'information sur ce projet référez-vous à l'article récent :

DIAGNOSTIC HIGHLIGHTSFAITS SAILLANTS EN MATIÈRE DE DIAGNOSTIC

First Case of Lymphoproliferative Viral Disease in Wild Turkey in Québec

This past May a female turkey exhibiting multiple skin masses on its head and having spent two days in a tree, seemingly unable to fly, was euthanized by staff with the Ministère des Forêts, de la Faune et des Parcs in Shawville, Québec.

The head of the turkey was submitted to CWHC-Québec at the Université de Montréal for analysis. The histological features of the masses were characteristic of infection with the lymphoproliferative viral disease of turkey. The presence of the virus that causes the disease was confirmed by PCR at the Ontario Veterinary College at the University of Guelph.

This disease was first documented in European turkey farms in 1978 and the first case of the disease being diagnosed in a wild turkey was in the USA in 2009. Although the source of the virus is unknown, surveys of USA populations suggest that approximately 50% of wild turkeys carry the virus.

You can read more about this case in our recent blog article:

Premier cas de maladie lymphoproliférative virale chez un dindon sauvage au Québec

En mai dernier une femelle dindon sauvage présentant de nombreuses masses cutanées sur sa tête et incapable de voler a été euthanasiée par le personnel du Ministère des Forêts, de la Faune et des Parcs a Shawville, Québec. La tête du dindon a été soumise pour analyse au RCSF - Québec à l'Université de Montréal. Les lésions histologiques observées étaient caractéristiques d'une infection par le virus de la maladie lymphoproliférative du dindon. La présence de ce virus chez ce dindon a été détectée par PCR au Ontario Veterinary College, University of Guelph.

Cette maladie a été documentée pour la première fois en 1978 dans des élevages de dindons domestiques en Europe. Les premiers cas de maladie lymphoproliférative diagnostiqués chez des dindons sauvages l'ont été aux États-Unis en 2009. Bien que l'origine de ce virus reste incertaine, des recherches effectuées sur ce virus indiquent qu'environ 50% des dindons sauvages américains sont porteurs du virus.

FEATURED PROJECTPROJET VEDETTE

West Nile Virus Surveillance

It has been a prominent year for incidents of West Nile virus (WNV) in wildlife across much of Canada. Wild birds are the primary host of the virus, which is transmitted through mosquito bites, with raptors and corvids being the most sensitive to the disease and represent the species with the highest mortality. The virus can infect mammals and can cause illness in humans and horses.

Through 2017 a total of 1921 animals were examined for symptoms of WNV. Of these 232 animals were tested for the virus and 142 tested positive. It was a record year for incidents of WNV in Québec with 85 positive cases identified from 114 wild birds that were tested, an eastern grey squirrel also tested positive for the virus. For comparison, a total of 57 positives were identified from wild birds from the rest of Canada. This includes 44 of 77 birds tested in Ontario testing positive, 11 out of 20 birds tested in Saskatchewan were found to be positive, and the only two birds from Manitoba that were tested were both found to be positive for the virus.

You can read more about CWHC-Québec’s record year in WNV surveillance and the results of CWHC-Ontario’s WNV surveillance in our recent blog articles, and you can read about our surveillance efforts on our WNV surveillance web page:

Virus du nil occidental

Ce fut une année importante pour le nombre d'incidents causés par le virus du Nil occidental chez les animaux sauvages à travers la plupart des régions canadiennes. Les oiseaux sauvages sont le réservoir principal pour ce virus qui est transmis par les piqures d'insectes. Les oiseaux de proie et les corvidés sont particulièrement sensibles à cette infection. Ce virus peut aussi causer des signes cliniques chez les mammifères, dont l'Homme et les chevaux.

En 2017, un total de 1921 animaux a été examiné pour des signes de VNO. Sur ce nombre, 232 animaux ont été testés et 142 se sont avérés positifs. Ce fut une année record en termes de nombre de cas au Québec avec 85 cas positifs identifiés sur 114 oiseaux testés. Un écureuil gris est aussi mort de cette infection. Un total de 57 cas positifs a été identifié chez des oiseaux dans les autres provinces, incluant 44 des 77 oiseaux testés en Ontario, 11 des 20 oiseaux testés en Saskatchewan et seulement 2 oiseaux sur 2 oiseaux testés au Manitoba.

DIAGNOSTIC HIGHLIGHTSFAITS SAILLANTS EN MATIÈRE DE DIAGNOSTIC

Outbreaks of Trichomonosis in Backyard Birds

In early July, CWHC-Atlantic began to accumulate reports of sick and dead finches exhibiting symptoms of infection with the parasite Trichomonas. Information provided by CWHC gained extraordinary exposure from the public and the media. This resulted in numerous media articles and interviews further disseminating the information about the disease. Subsequently, reports of potential incidents reported by the public from across Atlantic Canada rapidly accumulated.

In response to queries from the concerned public, the CWHC produced a new section in the surveillance section of our website specifically for trichomonosis outbreaks. Additionally, wildlife technician Darlene Jones of CWHC-Atlantic produced (and continues to update) a map indicating the locations of reported incidents. Reports of potential incidents would eventually extend throughout Atlantic Canada and into parts of Quebec and Ontario.

Épidémies de trichomonase chez des oiseaux de mangeoires

Au début de juillet, le Centre régional de l’Atlantique a commencé à recevoir de nombreux rapports de passereaux morts ou malades qui présentaient des signes cliniques d’infection par le  parasite Trichomonas. L’information transmise à cet égard par le RCSF a suscité un vif intérêt, à la fois chez le public et dans les médias. Les nombreux articles et entrevues diffusés dans les médias ont permis une transmission plus large de l’information entourant cette maladie. On a ensuite constaté une augmentation rapide du nombre de rapports d’incidents potentiels en provenance des habitants des provinces de l’Atlantique.

En réponse aux demandes des personnes intéressées, le RCSF a développé une nouvelle sous-section de surveillance consacrée spécifiquement aux épidémies de trichomonase sur son site web. Par ailleurs, Darlene Jones, technicienne en santé de la faune au Centre régional de l’Atlantique a développé une carte indiquant les lieux où des incidents ont été rapportés. Cette carte est continuellement mise à jour. Elle inclura éventuellement les rapports d’incidents provenant de toute la région de l’Atlantique ainsi que de certaines parties du Québec et de l’Ontario.

Renseignez-vous davantage sur les épidémies de trichomonase observées à l’Est du Canada au cours de l’été dernier.

CWD outreach and Surveillance in British Columbia

There is a looming threat of chronic wasting disease (CWD) spreading into BC from Alberta. In response to the potential spread of CWD into the province, the BC Provincial Fish and Wildlife Branch and CWHC-BC have been conducting targeted surveillance and proactive outreach. Regions of BC on the border with Alberta are considered at the highest risk for the introduction of CWD. Accordingly, surveillance and outreach has been focused in these areas since 2002.

Despite enthusiasm from regional contacts, hunter submissions in the Peace region have declined. Cait Nelson, BC’s wildlife health biologist and CWHC-BC Assistant Director accepted an invitation to speak to local clubs and businesses in the region to promote the CWD surveillance program. Cait also provided training in proper sample collection techniques to regional wildlife staff.

The surveillance program in BC has tested over 3400 cervids since the program began in 2002, with 350 animals tested during the 2016-17 surveillance season. Collected samples are sent to CWHC Western/Northern regional centre for analysis. To date all samples have tested negative for CWD.

The hope is that the momentum of the program from the previous few years will improve awareness of the disease and lead to increased sample numbers from target areas.

Sensibilisation à la maladie du dépérissement chronique et surveillance en Colombie-Britannique

Il existe une menace latente de transmission de la maladie du dépérissement chronique (CWD) entre l’Alberta et la CB. Pour se préparer à la transmission potentielle de cette maladie en CB, le BC Provincial Fish and Wildlife Branch et le Centre régional du RCSF de la CB ont entrepris des activités de surveillance ciblée et de sensibilisation proactive. Compte tenu que les régions limitrophes de l’Alberta sont considérées à plus haut risque d’introduction de la maladie, les activités de surveillance et de sensibilisation sont concentrées dans ces régions depuis 2002.

Malgré l’enthousiasme démontré par les personnes ressources à l’échelon régional, le nombre de soumissions de la part des chasseurs de la région de Peace a diminué. Cait Nelson, biologiste en santé de la faune de la CB et directrice adjointe du Centre régional de la CB, a accepté de faire la promotion du programme de surveillance de la maladie auprès de divers clubs locaux et entreprises de la région. Cait a aussi dispensé de la formation sur les techniques appropriées de collecte des spécimens au personnel régional en santé de la faune.

Depuis la mise en place du programme de surveillance de la CB en 2002, plus de 3 400 cervidés ont été soumis à des tests dont 350 pendant la saison de surveillance 2016-17. Les échantillons recueillis sont expédiés au Centre régional de l’Ouest et du Nord du RCSF pour être analysés. Les tests effectués sur tous les échantillons soumis jusqu’à maintenant se sont révélés négatifs relativement à la maladie du dépérissement chronique.

On espère que l’évolution de ce programme tout au long des dernières années améliorera la sensibilisation à la maladie et entraînera un plus grand nombre de soumissions d’échantillons à partir des régions visées.

FEATURED PROJECT

Massive efforts to understand giant losses

The spring of 2017 has been marred by an unprecedented number of whale deaths in Atlantic Canada and Québec. Staff of CWHC-Atlantic and CWHC-Québec have been integral to the efforts to determine the causes of death of these animals, in some cases traveling to remote areas and working in inclement conditions to complete important necropsies.

In May, staff from CWHC-Atlantic helped lead necropsies on a blue whale that washed ashore near Liverpool, Nova Scotia and on a Sowerby’s beaked whale on Sable Island, Nova Scotia; and CWHC-Québec conducted a necropsy on a stranded humpback whale in Godbout, Québec.

In the month of June, six right whales were found dead and floating in the Gulf of St. Lawrence. Collaborating with the Marine Animal Response Society, Fisheries and Oceans Canada, and the Canadian Coast Guard, staff from CWHC-Atlantic traveled to the floating carcasses in order to procure initial samples. Later in the month three of the whale carcasses were dragged ashore on PEI by the Canadian Coast Guard. A collaborative effort among CWHC, Fisheries and Oceans Canada, Marine Animal Response Society, University of North Carolina Wilmington, Université de Montréal, Marine Mammal Commission, and the government of BC resulted in successful necropsies of the three animals in as many days.

Also in June, staff from CWHC-Québec collaborated with Fisheries and Oceans Canada, the Marine Animal Response Society, Group for Research and Education on Marine Mammals, the Shedd Aquarium in Chicago, and the Vancouver Aquarium among many others in order to capture and relocate a young male beluga that had become trapped in a small portion of the Nepisiguit River, New Brunswick. The beluga was successfully relocated to the St. Lawrence Estuary proximal to a pod of other belugas. Prior to release, the young beluga was fitted with a transmitter that allowed for the movements of the animal to be monitored until contact was lost in early July.

DIAGNOSTIC HIGHLIGHTS

White nose syndrome surveillance

The CWHC’s national white nose syndrome surveillance continues to monitor for the presence of the fungal pathogen Pseudogymnoascus destructans (Pd) in hibernating bats. Between January 1 and March 31st 2017 a total of 13 bats have been examined from across Canada. Of the specimens tested one bat in Saskatchewan has tested negative and two have tested positive in Ontario. These positive test results from Ontario have identified the presence of WNS in a county where it had not previously been observed. The remaining specimens from New Brunswick, PEI, and Saskatchewan are pending results. To be considered positive for white nose syndrome bats must exhibit histologic lesions and Pd must be identified through PCR techniques or through fungal culture.

FEATURED PROJECT

Dissecting animal health

In February 2017, the Western/Northern and Atlantic Regional Centres conducted necropsy courses at the Western College of Veterinary Medicine at the University of Saskatchewan, and at the Atlantic Veterinary College at the University of PEI, respectively. These courses utilized specimens of opportunity in order to teach general anatomy, proper necropsy techniques, and indicators of animal health.

The course conducted by our Western/Northern centre was intended to teach government conservation officers and biologists from the Ministry of Environment and Parks Canada. Our Atlantic centre conducted a course focused on teaching students from the Wildlife Conservation Technology course at Holland College in PEI.

These hands on courses help train our partners operating in the field and educate students who may one day become wildlife health and conservation specialists. These courses help inform our existing and future partners about wildlife health issues and provide them with training in conducting important health assessments of wild animals found dead.

DIAGNOSTIC HIGHLIGHTS

Chronic wasting disease in Saskatchewan

In association with Ministry of Environment, the CWHC Western/Northern region at the Western College of Veterinary Medicine has been conducting targeted and scanning surveillance for Chronic Wasting Disease (CWD) among cervid species for the past 20 years. With close to 46,000 cases examined the CWHC has tracked the geographic and species spread of this disease across Saskatchewan. In 2016 approximately 300 animals were examined, 32 of which were positive for CWD including animals from new geographic locations in Saskatchewan. In addition to surveillance the CWHC is also involved in research aimed at providing additional management options to promote healthy deer, elk and moose populations in this region.

On the Bighorns of a Dilemma: wild and domestic sheep in BC

Since early last century and maybe before, a correlation between the introduction of domestic sheep and declines in bighorn sheep populations were noted.  Pneumonia outbreaks resulting in 30-90% mortality in previously healthy bighorn sheep populations were often followed by years of poor lamb recruitment.  Despite decades of research into the causes of these die-offs, it is only recently that researchers were able to find convincing evidence of at least one trigger, a species of bacteria, Mycoplasma ovipneumoniae.

FEATURED PROJECT

Wildlife Health Intelligence Platform

The CWHC is pleased to announce that the development of our next generation of wildlife health information software is under development.

In the last 25 years, approximately 500,000 animals have passed through the hands of CWHC staff for either a diagnostic assessment or testing for a specific disease. That information is stored in a centralized national database, which enables wildlife health professionals to store and access their own data and view similar data from across Canada.

The current system is designed with this data storage and access focus in mind. Our new system is designed to take the next step and help transform data into knowledge so that it is more useful to more people and more responsive to emerging questions and scenarios. In addition to diagnostic and testing data, the system will handle observational data (e.g. citizen science) and external sources of data in a bid to broaden our scope of knowledge and provide a better tool set for decisions makers in a wildlife health context.

CWHC recently received funding from Agriculture Canada and Agri-food Canada to speed up the development of this new platform and we anticipate that the new system will be ready for beta testing in January of 2018 with a full release scheduled for March 30 of 2018.

The new Wildlife Health Intelligence Platform (WHIP) will allow the CWHC to grow its reputation as the international standard for national wildlife health programs.

DIAGNOSTIC HIGHLIGHTS

Discovery of Whirling Disease in Canada

  • In August 2016, Parks Canada noted some brook trout (Salvelinus fontainalis) with suspicious swimming behaviour at Johnson Lake in Banff National Park.
  • The BC Animal Health Centre/CWHC BC diagnosed the fish with the first known Canadian case of whirling disease, a parasitic infection caused by Myxobolus cerebralis.
  • The parasite infects the bony tissues of the head, vertebra and fins of salmonids causing the characteristic whirling swimming pattern.
  • The disease can cause significant mortalities in fish populations.

Trichomonosis now in Ontario as well as Atlantic Canada

  • Further to the cases of trichomonosis diagnosed in PEI this spring, more purple finches, goldfinches and pine siskins with trichomonosis infections were seen in Newfoundland, New Brunswick and eastern Ontario, indicating the disease may be spreading in Canadian finches.
  • Trichomonosis is an infectious disease caused by a parasite that causes lesions in the throat.  Affected birds may drool, regurgitate, have difficulty swallowing or breathing.  Emaciation is common.
  • Bird feeders and baths can be sites of transmission for the parasite.  A new factsheet is available for download to raise awareness of this disease in feeder birds. http://www.cwhc-rcsf.ca/fact_sheets.php

FEATURED PROJECT

Assessing Beluga Health in the Beaufort Sea

In July 2016, a team including veterinarians from the CWHC Québec and the Department of Fisheries and Oceans partnered with Inuvialuit hunters from Tuktoyaktuk, NWT  to perform health assessments on belugas whales harvested in the Beaufort Sea.  

Complete necropsies were carried out, samples taken for histological examination, assessment for parasites, blood chemistry, contaminants, genetics, dietary studies and screening for other infectious agents.

The results will be shared directly with communities in the Inuvialuit Settlement Region providing information on the safety and security of the Beaufort beluga population as a food source.

This is part of a long-term monitoring project that involves many partners including the Fisheries Joint Management Committee & the University of Saskatchewan.

DIAGNOSTIC HIGHLIGHTS

Death by dinner: Barred Owl vs. rough-skinned newt

  • In April, a Barred Owl (Strix varia) was submitted to the BC Animal Health Centre, home of the BC node of the CWHC.  The owl was emaciated and had a mostly-intact rough-skinned newt (Taricha granulosa) in its proventriculus (the avian equivalent of a stomach).
  • Rough-skinned newts are extremely toxic, producing a type of tetrodotoxin, a potent neurotoxin most famously occuring in pufferfish.  Most newts can produce enough toxin to kill 25,000 mice, earning them the title of the most toxic amphibian in the Pacific Northwest.
  • Because they are so toxic, rough-skinned newts are highly unusual prey for most animals. In this case, the owl was severely emaciated, so perhaps starvation drove it to eat this highly unusual prey-item.

Trichomonosis in PEI finches

  • In June 2016, residents reported unusual mortalities of purple finches (Carpodacus purpureus) in several areas of PEI.  Carcasses were submitted to the Atlantic Region of the CWHC where a diagnosis of Trichomonosis was confirmed. 
  • Trichomonosis is an infectious disease caused by the Trichomonas parasite.  Due to lesions in the throat, affected birds may drool, regurgitate, have difficulty swallowing or show laboured breathing.  Emaciation is common.
  • Rarely diagnosed in the past, it is increasing common in finch populations in Atlantic Canada.  Trichomonosis in the United Kingdom is associated with significant population declines in some finch species.
  • The disease is transmitted by feeding regurgitated food to young during the breeding season and by contaminated food and water.  Bird feeders are a common site of transmission.
  • CWHC engaged with nature and birding organizations in PEI on social media to raise awareness of the disease and recommend temporary removal of bird feeders and feeder disinfection.  Reports of dead or sick finches is recommended to better understand the impacts of the disease.

BC responds to threat of White-nose syndrome

Since white-nose syndrome was discovered in Washington State, BC has ramped up monitoring efforts.  A network of community bat projects have been submitting bat mortalities.  Recent tests of 24 bats were negative for P. destructans.  Surveillance will continue as it is critical to detect entry of the fungus into the province early so as to slow the spread of the disease.

First European detections of Chronic Wasting Disease in reindeer and moose.

A wild reindeer was discovered with CWD in Norway in April 2016. This was the first documented case in a wild reindeer and in Europe.  In May and June, two moose almost 300km from the reindeer, were also confirmed to have the disease.  The spread of CWD in Europe is concerning as once the disease is established it has proven near impossible to eradicate.  What is of grave concern to Canadians, is the occurrence of CWD in a wild reindeer which indicates that CWD (currently well known in Saskatchewan deer) could spread to Canada's caribou populations many of which are already at risk

CWHC engaging with trappers

Parasites can have an impact on wildlife health but also can reduce the quality and value of pelts. There is concern that dog louse is increasing, particularly in coyotes, leading to animals with "shoulder patches", where guard hairs are damaged by chronic scratching.  Lice are not a cause of mortality, but studies suggest that severely infested canids have a higher probability of contracting other diseases. The CWHC is building partnerships with trappers and the fur industry to monitor parasites and other diseases of interest.

2015 a tough year for black bears

The BC Animal Health Centre noticed high numbers of cub abandonments and stunted growth in black bears in 2015.  Investigations suggest that a significant number were infected with an apicomplexan parasite, Sarcocystis spp. The parasite may have affected feeding and increased risk of trauma for the bears.  This combined with poor berry crops may have lead to malnutrition and an increased tendency to abandon cubs.

FEATURED PROJECT

Health Intelligence for the modern age

CWHC Ontario/Nunavut in partnership with Wilfrid Laurier University and the CWHC National Office are currently developing and piloting a web-based reporting tool that aims to enhance wildlife disease surveillance in Ontario. It is important to incorporate wildlife health and disease knowledge into domestic animal and public health planning and disease management. Web-based reporting of wildlife mortality and morbidity events in wildlife populations will enable us to fill important gaps in our disease surveillance activities.

There are 3 main components to this project: 1) development of the tool; 2) piloting the tool with select groups of hunters and biologists; and 3) assessment of the tool as a way to enhance ongoing wildlife disease surveillance activities in Ontario. Our long term goals are to adapt and distribute the tool for use by other groups with interest in wildlife health and disease and explore options to link this tool with other wildlife related citizen science initiatives.

This project was partially funded by the OMAFRA-University of Guelph Strategic Partnership, under the Disease Surveillance Plan, which is a joint federal-provincial Growing Forward 2 project.

DIAGNOSTIC HIGHLIGHTS

Snake fungal disease found in Ontario

The presence of snake fungal disease has been confirmed in Ontario by CWHC Ontario/Nunavut. A female eastern foxsnake with dermatitis was found near Lake Erie and treated in captivity. Samples were submitted to the CWHC because the lesions were consistent with snake fungal disease. The presence of the fungus Ophidiomyces ophiodiicola (the agent causing snake fungal disease) was confirmed by culturing the fungus as well as by PCR, and snake fungal disease was confirmed with histological examination of a full depth skin biopsy. This is believed to be the first documented case of snake fungal disease in Canada. The disease has previously been confirmed in 16 US states.

Brain abscesses in male white-tailed and mule deer

CWHC Western/Northern has received a larger-than-usual number of submissions this winter involving brain abscesses in male white-tailed and mule deer. The deer were typically reported acting abnormally, appearing to be blind or uncoordinated, or in some cases being found down and unresponsive. In several cases, the cause was found to be infection beginning at the base of one or both antlers and extending through the bones of the skull and into the brain, resulting in a pus-filled abscess. CWHC Ontario/Nunavut also diagnosed brain abscesses in two white-tailed bucks during this past winter.
The explanation for the cluster of cases this winter is unknown, but the occurrence of brain abscesses in male deer is not uncommon; it is thought to be related to behaviour prior to and during the rut. Antler rubbing and sparring with other bucks can result in trauma to the antler base, which serves as an entry point for bacteria. The bacteria Trueperella pyogenes, which is commonly found on healthy animals, was most frequently isolated from the abscesses.

White-nose syndrome in Washington

In March, 2016, white-nose syndrome was diagnosed in a dead little brown myotis found in Washington state, over 2,000 km outside of the previously known range of the disease. This devastating disease has been spreading west since it was first reported in North America in 2006, but its sudden appearance on the west coast was unexpected. Neighbouring British Columbia has responded to the implications of this finding by increasing surveillance for the disease and urging the public to report unusual bat activity.

Cuvier’s beaked whale stranding in Atlantic Canada

A Cuvier’s beaked whale was found stranded on a beach in New Harbour, Nova Scotia. Aside from one possible case on Sable Island, the species has never before been found stranded in Atlantic Canada. CWHC Atlantic carried out a necropsy the whale, but were unable to identify a definitive cause of the stranding. New Brunswick Museum plans to display the whale’s skeleton in their ‘Hall of the Great Whales’ exhibit.

FEATURED PROJECT

Wildlife as sentinels for climate change

Climate change represents one of the most significant public health risks worldwide. The effects of climate change are evident and ongoing in Canada. Given the uncertainties associated with climate change it is critical to systematically scan the environment for early warning signals that could inform public health decisions in advance of human harm. The purpose of an early warning system is to empower individuals, communities and/or organizations to respond in a timely and appropriate manner in order to avoid, reduce or mitigate harm.

There is an extensive history of wildlife serving as bio-sentinels for the effects and distribution of environmental pollutants and pathogens. The role of wildlife as bio-indicators is anticipated to increase given the expectation of changing distributions and burdens of pathogens and pollutants in the face of climate change. Wild animals can also signal vulnerabilities in social determinants of health and resilience. These contributions are made through their role in food security, income, and social capital. Climate change is anticipated to impact the distribution and abundance of wildlife, thereby affecting their public health impacts, particularly in northern and rural areas.

In partnership with the Public Health Agency of Canada and working with international colleagues from within our network, the CWHC recently examined the potential for wildlife to contribute to the early warning system for public health preparedness of climate change in Canada. In this analysis the CWHC identified five scenarios where wildlife are likely to help us anticipate how climate change will affect communities. The end result is a proposed approach to support proactive planning.

FEATURED PROJECT

Analysis of wetland sediment for avian influenza surveillance

The avian influenza (AI) outbreaks of 2014/2015 on poultry farms highlighted the need for a seasonal early warning system for the presence/absence of AI viruses in wild waterfowl. This would allow producers and government to implement biosecurity and surveillance measures appropriate for the level of risk. CWHC BC developed a new approach to this problem based on genomic analysis of wetland sediments. Given that waterfowl congregate on wetlands, the BC team recognized the potential of testing wetland sediments to efficiently screen a large number of waterfowl encompassing a wide range of potential reservoir species. So far, the technique appears quite promising, as they were able to detect AI virus in up to 37% of sediment samples. They are further analyzing PCR-positive samples to characterize the AI viruses, and conducting analysis in conjunction with a waterfowl ecology study to better understand the dynamics of AI in the environment. The next step is to meet with local, provincial, and national stakeholders to share results and discuss the next steps for validating and implementing AI sediment surveillance. Ultimately, the goal is to use sediment surveillance as the cornerstone for developing an effective provincial AI early warning system.

Newly developed snake fungal disease diagnostic test

  • Snake fungal disease has been identified in US snakes since the 1990s and could pose a major threat to snake populations in Canada.
  • There is a need for consistent methods to diagnose this disease in snakes. CWHC Ontario/Nunavut has responded to this need by developing a diagnostic test to detect the fungus associated with the disease.

WILDLIFE HEALTH TRACKER

Bluetongue in cattle

In September, a case of bluetongue was confirmed on a Southwestern Ontario cattle farm, a finding that has implications for international trade. CWHC Ontario/Nunavut has increased vigilance for epizootic hemorrhagic disease virus (EHDV) in wildlife, particularly deer, due to the close relationship between the viruses and their shared vector: biting midges of the Culicoides genus.

 

Beluga update

Overall, there were fewer reports of deaths in St. Lawrence beluga whales in this past year. Despite the good news, three of the seven carcasses examined by CWHC Quebec were found to have died during parturition, which is an unusually high number. Earlier in the year, a beluga whale found dead in the region was found to be a case of hermaphrodism, a condition rarely seen in wild or domestic animals.

FEATURED PROJECT

Bat White-nose Syndrome program enjoys success

The Canadian National Bat White-nose Syndrome (WNS) Coordinator position is embedded in CWHC, Atlantic Region; Jordi Segers is the current coordinator. Since the Federal listing of the three species of bats most affected by bat WNS under the Species at Risk Act, Jordi and the CWHC have not only focussed on disease response but have become integral partners in the effort to recover the bat populations affected by WNS.

Recent successes in program delivery include a revision of the decontamination protocol for people entering bat hibernacula and provision of technical expertise for the production of Parks Canada’s instructional video on decontamination procedures; proper decontamination is crucial to limit further spread of WNS. Additionally, CWHC Atlantic Region’s Scott McBurney and Jordi Segers have developed and implemented a bat monitoring and inventory program for Prince Edward Island National Park based on the North American Bat Monitoring Program. This program allows the park to meet Parks Canada Agency’s ecological integrity mandate and visitor educational and outreach requirements.
