By Scott Weese on Posted in Dogs,Other diseasesAs I’ve mentioned in a previous post, this seems to have been a bad year for leptospirosis in dogs in various areas. In at least a few location in Ontario, we are seeing a very high rate of disease, well beyond what we’ve seen before. I was giving some talks in Buffalo the other day… Continue Reading
By Scott Weese on Posted in Dogs,VaccinationLeptospirosis is a potentially nasty bacterial infection that can cause severe kidney disease (among other things) and is acquired from the environment, in cool damp areas that are contaminated with urine from infected reservoir hosts (e.g. rats, raccoons, other wildlife). It can also potentially be transmitted to people through contact with urine from an infected… Continue Reading
By Scott Weese on Posted in RabiesAs expected, rabies continues to be an issue in Ontario following the emergence of raccoon rabies in the Hamilton area in late 2015, and a separate emergence of fox rabies northwest of there around the same time. Hopefully raccoon rabies will be eradicated, as it was the first time it entered the province (1999-2005), but… Continue Reading
By Scott Weese on Posted in Other animals,RabiesHere’s the latest map of the terrestrial rabies cases in southwestern Ontario. Raccoon-variant cases still centre on the Hamilton area. It was never assumed that this particular outbreak would be eliminated quickly, given the case numbers seen in the first several months and the additional challenges of trying to control the spread of the virus in… Continue Reading
By Scott Weese on Posted in Parasites,Rabies1) Pick up baby raccoons and take them away Rarely does this end well. It’s illegal in many areas (including Ontario). Raccoons don’t do well long-term in households for various reasons (their curious and destructive nature being a big one). And, they are potential sources of a number of zoonotic diseases (rabies being a big one but not… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other animals,Rabies,VaccinationThis month, Public Health Ontario released a new Rabies Guidance Document for Healthcare Providers. It’s nothing particularly new but a good review of the recommended response to rabies exposure from various animal species, something that’s unfortunately often messed up or made more complicated than necessary. It includes some nice flowcharts, such as the one below. The full… Continue Reading
By Maureen Anderson on Posted in RabiesIt has been just over 1 year since the discovery of the first rabid raccoon in Ontario in over a decade, and the first rabid wildlife in the Hamilton area in over two decades. Since then well over 4500 abnormal or “found dead” wildlife have been tested, and 253 animals carrying raccoon-variant rabies have been… Continue Reading
By Scott Weese on Posted in Other animals,ParasitesThe US Geological Service isn’t the first thing that comes to mind when I think about publishers of zoonotic disease information (but what do I know?). If you’re looking for some holiday reading, the USGS has published a comprehensive overview of Baylisascaris larva migrans, a serious disease caused by Baylisascaris procyonis, the raccoon roundworm. This parasite… Continue Reading
By Scott Weese on Posted in Other animals,ParasitesThe August edition of Emerging Infectious Diseases has an interesting case report of Baylisascaris procyonis infection in a California man (Langelier et al. 2016). Baylisascaris procyonis, commonly known as the raccoon roundworm, is a parasite that is very commonly found in the intestinal tracts of raccoons. Massive numbers of parasite eggs can be found in… Continue Reading
By Scott Weese on Posted in RabiesWhen raccoon rabies re-emerged in Ontario last fall, one of the big questions was “where did it come from?” It had been eradicated from the province and control measures were in place at the borders to reduce the risk of re-introduction. It was assumed that a rabid raccoon hitched a ride across the border from… Continue Reading
By Scott Weese on Posted in RabiesRaccoon rabies continues to be a concern in the Hamilton, Ontario area. After being eradicated in Ontario for years over a decade, raccoon rabies snuck back into the province late last year. Intensive surveillance and baiting efforts by the Ministry of Natural Resources and Forestry (MNRF) continue. Almost half a million oral rabies vaccine baits… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other animals,Rabies,VaccinationSuccess can breed apathy. Apathy can lead to bad decisions. That’s a common problem with vaccinations. People lose sight of why we vaccinate. Growing up during a time when many major pathogens have been controlled by vaccines, it’s easy to forget about how bad those diseases are. Whether it’s resurgence in measles in people because… Continue Reading
By Maureen Anderson on Posted in Cats,Dogs,Horses,RabiesIt seems to be a bit of a slow month for zoonoses. Finally getting some cold weather here in Ontario certainly helps keep many bugs at bay (and people indoors). Nonetheless, rabies continues to keep us hopping. The Ministry of Natural Resources and Forestry (MNRF) is continuing with its surveillance efforts around the cluster of… Continue Reading
By Maureen Anderson on Posted in Cats,Dogs,Rabies,VaccinationThe incursion of raccoon rabies in the Hamilton ON area reached a total of 10 confirmed cases as of last week. A map of the current MNRF control zone is available on the OMAFRA website. This is the area where the Ministry of Natural Resources and Forestry (MNRF) has spread oral rabies vaccine (ORV) baits… Continue Reading
By Maureen Anderson on Posted in RabiesAs they say, when you look you find. After a sick raccoon in Hamilton had an altercation with two dogs last week and subsequently tested positive for rabies, the Ministry of Natural Resources and Forestry (MNRF) tested an additional 14 raccoons and three skunks that were picked up by Hamilton Animal Services since then. These… Continue Reading
By Maureen Anderson on Posted in Dogs,RabiesLast week, a sick raccoon in Hamilton, Ontario got into an altercation with two bull mastiffs in the back of an animal services van. The story quickly hit the media (and social media). Because the raccoon was not acting normally (and was actually reportedly very aggressive), it was euthanized. Because it also had direct contact with… Continue Reading
By Scott Weese on Posted in ParasitesI had a question the other day about roundworms in feral cats. Specifically, how do you deworm a group of cats that you don’t handle and may not be able to catch? There are a few possible approaches, from trapping and treating (oral or topical) to trying to get a dewormer into them via food.… Continue Reading
By Scott Weese on Posted in DogsI’ll admit it – I don’t understand dogs. How is it that they have this incredibly well-developed sense of smell, but my dog feels it necessary to roll in the most disgusting smelling things he can find? I guess it’s not that he feels like he needs strong body odour, just that he has a… Continue Reading
By Scott Weese on Posted in RabiesA recent report about a rabid raccoon in New Brunswick highlights a few different issues regarding rabies exposure, and the marked differences in application and interpretation of various guidelines. The incident occurred in St. Stephen, New Brunswick, where a family came home "to find their 2 dogs excitedly circling around something in the yard. The… Continue Reading
By Scott Weese on Posted in Other animalsThere’s been some controversy in the past regarding allowing pets to sleep in or on the bed. I don’t get too worked up about it, since I think it’s very low-risk in terms of disease transmission for most pets and households, but a variety if reasons for prohibiting this practice have been given. I haven’t… Continue Reading
By Scott Weese on Posted in ParasitesAn article by Dr. Ann Britton of British Columbia’s Animal Health Centre (AHC) on the blog site healthywildlife.ca is another reminder of the perils of raccoon poop. Over a 2 year period, 17 raccoons were submitted to the AHC for necropsy, and 12 (71%) of them were infected with Baylisascaris procyonis, the raccoon roundworm. The… Continue Reading
By Scott Weese on Posted in Other animalsThis time of year, it’s very common around here to see young raccoons wandering about. It’s also still pretty common to hear about people keeping a litter of baby raccoons in their house. I can understand the appeal – they’re cute and entertaining. However, in addition to being illegal in many regions, handling young raccoons… Continue Reading
By Scott Weese on Posted in DogsThere have been various news reports from different parts of North America describing distemper outbreak in raccoons. Distemper is a viral infection caused by canine distemper virus, which is related to the human measles virus (but the canine version can’t infect people). A variety of animal species in addition to dogs can get distemper, most… Continue Reading
By Scott Weese on Posted in DogsMax, a 12-year-old Chihuahua from Greenfield, New Jersey, was euthanized recently after he was exposed to rabies. While far from unusual, the case highlights the ongoing risk of rabies exposure as well as issues with understanding of rabies guidelines and communication. Max was attacked by a rabid raccoon – an ever-present risk for animals that… Continue Reading
