By Scott Weese on Posted in Deworming,Dogs,ParasitesNothing has changed about Echinococcus multilocularis (the fox tapeworm) in the past couple of months, but my phone is ringing off the hook following another round of media reports about this parasite. Here’s a recap of the issues: Echinococcus multilocularis is a small tapeworm normally found in the intestinal tract of wild canids (e.g. coyotes, foxes)… Continue Reading
By Scott Weese on Posted in Cats,DogsA recent presentation at ECCMID (European Congress of Clinical Microbiology and Infectious Diseases) in Amsterdam described a series of linezolid-resistant enterococci in dogs and cats in the UK. I’m only able to get information from media reports, so details are limited (and potentially lost in translation); however, it’s an interesting story. It’s unsurprising in many… Continue Reading
By Scott Weese on Posted in Cats,Dogs,ParasitesI keep saying spring is approaching and I keep getting disappointed by the cold weather. But it’s going to happen soon, so we’ve been gearing up for tick season. There are a few new initiatives underway for tracking ticks and tickborne diseases in Canadian dogs and cats. Check out the recent post at PetsAndTicks.com for more… Continue Reading
By Scott Weese on Posted in Cats,DogsThe snowfall we had on the weekend notwithstanding, spring is here. As the weather warms up in Ontario (and other regions), we have to once again think more about ticks. Once the temperature reaches ~4C, hungry ticks that didn’t feed in the fall will come out, looking for food. Accordingly, tick prevention for people and… Continue Reading
By Scott Weese on Posted in Cats,DogsRaw diets have been in the news a lot lately because of Salmonella contamination. It’s not surprising at all since bacteria like Salmonella, E. coli, Campylobacter and Listeria are expected to be found in raw meat (that’s why we cook it). We know that dogs and cats fed raw meat are at increased risk of… Continue Reading
By Scott Weese on Posted in DogsI guess we’re not the only ones dealing with Brucella canis issues lately. In February, we were dealing with B. canis in dogs imported into Ontario from South Korea. Currently, we’re dealing with a larger issue in commercial dog breeding facilities in Ontario. Imported Brucella canis also appears to be an issue in the US… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationRabies vaccination of dogs is legally required in many areas. In most of those, it must be given by a veterinarian, unlike some other vaccines that can be purchased from a veterinarian or supplier and administered by owners. Why does a veterinarian have to administer rabies vaccines? There are a few reasons. One is that… Continue Reading
By Scott Weese on Posted in Dogs,Other diseases,VaccinationI’ve had a few discussions with people over the past week about geographic variation in disease risk. It’s a great subject because it’s an important and often overlooked issue. Whether it’s animals being imported, animals moving with their owners, animals accompanying owners on vacation or animals being moved between regions within the county, movement between… Continue Reading
By Scott Weese on Posted in Other animalsAnd now for something completely different. We’ve studied Clostridium difficile in my lab for years and we probably have one of the world’s most diverse collections of this important bacterium. We have thousands of isolates from people, pets, livestock and many different wildlife species (as well as from meat, vegetables and water). Most of the… Continue Reading
By Scott Weese on Posted in Dogs,RabiesI’m taking a Brucella break to post a few interesting rabies stories. More rabies in Nunavut A rabies warning was issued to residents of Taloyoak, Nunavut in response to identification of rabies in “a number” of dogs and foxes (I’m not sure what that number is). This isn’t really new, as Arctic fox rabies is… Continue Reading
By Scott Weese on Posted in Dogs,Other diseasesThis is another one of those “I can’t say much specific because of privacy laws, but there’s so much social media paranoia that I have to say something.” Is there concern about Brucella canis in Ontario? Yes. We have been concerned about this bacterium for a while, particularly in imported dogs and commercial breeders (including… Continue Reading
By Scott Weese on Posted in Deworming,Dogs,ParasitesEchinococcus multilocularis (EM) is an important zoonotic tapeworm. The situation with this parasite in Canada (and probably the US) is unclear and evolving. It’s increasingly clear that EM is present in a high percentage of wild canids (e.g. coyotes, foxes) in some regions. What this means for human health isn’t clear yet. This tiny tapeworm lives… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationWe often talk about rabies in the context of high GDP countries, focusing on wildlife rabies and exposure during travel. However, in many parts of the world, exposure to canine rabies is an ever-present risk, and there can be substantial barriers to getting proper post-exposure prophylaxis (PEP) when needed. That’s part of the reason tens… Continue Reading

To download the infographics in pdf format, visit oahn.ca at these links: Treatment… Continue Reading
By Scott Weese on Posted in DogsI’ve been holding off on this post because the situation is still evolving, but there’s enough of a rumour mill developing (and I’m getting enough emails from concerned people) that I thought I should respond. A little background: Brucella canis is a bacterium that can cause a variety of issues in dogs (particularly reproductive issues),… Continue Reading
By Scott Weese on Posted in Cats,DogsHot off the press… the newest edition of the International Society for Companion Animal Infectious Diseases (ISCAID) guidelines for the diagnosis and management of bacterial urinary tract infections in dogs and cats has been published in The Veterinary Journal. These are updated and expanded clinical guidelines that have been in the works for the past… Continue Reading
By Scott Weese on Posted in Dogs,Other diseases,VaccinationHere’s a report from Cornell University’s Animal Health Diagnostic Center, describing importation of a canine distemper strain that hasn’t been found before in North America: 02/05/2019: (N. America) In early October of 2018, a 12-week old “Sheltie” arrived from Korea. Approximately 12 days later, the dog began with a cough and lethargy with blood work indicating… Continue Reading
By Scott Weese on Posted in Cats,DogsWe’re getting ready to launch the Canadian Pet Tick Study, with funding from the OVC Pet Trust. We’ve had great response from veterinarians in Ontario, but need more clinics from other provinces, so please share this link with out-of-province veterinary colleagues who may be interested! Details are available here: https://www.petsandticks.com/news/calling-all-veterinary-clinics-join-the-canadian-pet-tick-survey… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationIt’s easy to get complacent about rabies, even when you live in an endemic region. While we have ample bat rabies, Arctic fox rabies and raccoon rabies in Ontario, spillover into domestic animals is relatively rare. Success can breed complacency, though. When control measures work, it’s easy to forget why they are so important. That’s… Continue Reading
By Scott Weese on Posted in HorsesA common limitation of studies or case reports of zoonotic pathogens or infections is that they are one sided – they often just discuss the human case(s), or they just report carriage of a pathogen in animals. Case reports of human infections often only go as far as saying something along the lines of “this… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Rabies,VaccinationHere are some more leftover questions from the talk I did a talk recently for Third Age Learning in Guelph: As West Nile virus seems to be spreading, is there a vaccine becoming available for the general population? Probably not, but that’s just a guess. While it should be possible to make an effective human… Continue Reading
By Scott Weese on Posted in Cats,Dogs,RabiesI did a talk recently for Third Age Learning in Guelph, and there was an abundance of questions. I didn’t get through them all at the time, so I figured I’d address some of them here: Do mice carry rabies? Mice aren’t rabies reservoirs like raccoons, skunks or bats, as they don’t have a rabies… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Rabies,VaccinationBefore the emails start rolling in… yes, it’s from a satire site. See Dr. Sarah Boston (veterinary cancer surgeon extraordinaire)’s take on how veterinarians are misleading people into protecting people. EXPOSED – Vaccination of Pets Found to be Part of Larger Plot to Prevent Rabies in Humans… Continue Reading
By Scott Weese on Posted in Dogs,SalmonellaThe Minnesota Department of Agriculture has recalled some lots of raw pet food from Woody’s Pet Food Deli, after linking them to a human infection. The link isn’t definite, but was obviously enough to prompt a recall. The situation involves a person who developed salmonellosis and, as is typical, an investigation of possible sources ensued.… Continue Reading
