More Turtle-Associated Salmonellosis

Posted in Reptiles, Salmonella
In what shouldn’t come as a surprise, I guess, another pet turtle-associated multistate outbreak of Salmonella infection in people has been identified in the US. Despite the fact that the sale of small (<4 inch shell length) turtles has been banned in the US for decades, the law is widely ignored, and kids get sick… Continue Reading

Public Health Agency of Canada: Healthy Pets, Healthy People

Posted in Other animals, Pocket pets, Reptiles
The Public Health Agency of Canada, along with various partners (including the Worms&Germs team), has developed a set of informational postcards and a poster targeting pet owners and prospective pet owners.  They emphasize five critical steps for safe pet ownership and provide a visual reminder using infographic icons: WASH (your hands) DISINFECT (contaminated surfaces and… Continue Reading

According to an alert from the College of Veterinarians of British Columbia: The BC Centre for Disease Control is collaborating with BC health authorities, the Public Health Agency of Canada, and Health Canada to investigate an outbreak of Salmonella infections in British Columbia likely related to raw pet food. Raw pet food is food served… Continue Reading

“Show Me the Evidence”….Maybe

Posted in Dogs
When we’re faced with making decisions about treatments, “show me the evidence” is a common refrain. There are a lot of products being sold as “cures” but with little or no evidence to back up their claims. So, looking for any scientific backing is important.  One of the highest levels of evidence would be a… Continue Reading

Vaccine Apathy

Posted in Cats, Dogs, Other animals, Rabies, Vaccination
Success 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

Hermit Crab Zoonoses

Posted in Other animals
It seems like s a bit of an oddball question, but it’s come up a couple times in the past few weeks: Are there any human health risks posed by hermit crabs? My standard line is that there is no such thing as a zero-risk animal. That’s not an anti-pet sentiment, it’s just life. The… Continue Reading

More Canine H3N2 Influenza in Cats

Posted in Cats, Dogs
Perhaps unsurprisingly, canine H3N2 influenza has been found in a group of cats in the US. Canine H3N2 influenza is the strain that emerged in the US last year. It was likely imported (in a dog) from South Korea, and then spread through many parts of the country. As with H3N8 canine flu, we’ve been… Continue Reading

Cache Valley Virus in Dogs (and People)

Posted in Dogs, Other animals
Cache Valley Virus (CVV)has been in the news around here lately. This mosquito-borne virus can be found in various parts of North America, particularly in the southeastern US. It’s been present in Ontario for a while, but has hit the news recently because of a recent outbreak in sheep flocks in the province. CVV infection in… Continue Reading

Blastomycosis Screening in Dogs

Posted in Dogs
I had an interesting question the other day about blastomycosis screening. Blastomycosis is a nasty fungal disease caused by Blastomyces dermatitidis. The infectious form of this fungus (spores) lives in the environment, and dogs (and other species, including people) can develop serious disease after inhaling fungal spores (or being otherwise inoculated with spores, e.g. through… Continue Reading

Maybe Your Cat Isn’t Making You Crazy

Posted in Cats, Parasites
Headline writers have had a lot of fun over the past few years writing about toxoplasmosis and potential associations with neurological and behavioural disorders in people. Cats are the main natural host of Toxoplasma gondii, so “crazy cat lady” and other predictable headlines have ensued. But, what is the real risk? The answer is still… Continue Reading

Babesiosis in a Puppy: Ontario

Posted in Dogs
While it’s unlikely that any given patient will have a rare disease, we need to remain vigilant for such conditions because they’re easy to miss. That’s just common sense – if we rarely see something, it doesn’t jump to mind when examining a patient. Babesiosis is one such disease. It’s seen commonly in some regions, but it’s really rare… Continue Reading

Lungworm in Ontario dogs

Posted in Dogs, Parasites
Another emerging disease we’ve been paying attention to lately is canine lungworm. Lungworm is a generic name for infection caused by one of a few different parasites that live in the respiratory tract. A variety of different lungworms can cause disease in different species, and there tends to be a lot of regional variation. Recently,… Continue Reading

Zika virus and animals

Posted in Other animals
I’ve been getting a lot of questions about Zika virus and animals. It’s great to see that people are thinking more broadly about infectious diseases (but it isn’t doing much for my productivity this week). To recap, Zika virus is a mosquito-borne virus related to West Nile virus and dengue virus. Most people that are… Continue Reading

10 More Rabid Raccoons in Hamilton

Posted in Cats, Dogs, Horses, Rabies
It 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

More on urban chickens: Part II

Posted in Birds, Salmonella
A reasonable question, expanding on the recent discussion about urban chickens and disease risks, is: why don’t we know how often people get sick from urban chickens? To answer the question, we need to think about how diseases are diagnosed and reported. Let’s say I decide to raise some chickens in my backyard. (Very hypothetical since… Continue Reading

More on urban chickens: Part I

Posted in Birds, Salmonella
Urban chickens continue to be in the news, with debate about instituting (or enforcing) bylaws banning or restricting the raising of chickens in backyards running next to articles on how to raise your own backyard flock. People have various concerns, including: Noise Attracting wildlife, including predators such as coyotes Smell Infectious diseases Animal welfare But,… Continue Reading

Rabies in a horse

Posted in Horses, Rabies, Vaccination
A horse in South Carolina was recently diagnosed with rabies. While rabies is common in some animal species in some regions, it’s a pretty rare disease in horses, so it’s a noteworthy event. This case has a couple of important takeaway messages. Rabies can be sneaky. Rabies (especially in horses and cattle) isn’t always obvious… Continue Reading

Rabies in a calf: Ontario

Posted in Other animals, Rabies, Vaccination
In a rather unusual development, a calf in Ellice Ward, Ontario has been diagnosed with rabies. It’s the first case of rabies in any animal species in Perth County since 2012, and looking at the Canadian Food Inspection Agency surveillance records, it’s the first rabid bovine in Ontario since 2011. Rabies has been in the… Continue Reading

Rabies baits and feral cats

Posted in Cats, Dogs, Rabies, Vaccination
The 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

Imported canine rabies…US

Posted in Dogs, Rabies, Vaccination
Rabies is a hot topic around here lately, with the recent identification of raccoon rabies in the province. The virus probably inadvertently arrived in Hamilton via a raccoon hitching a ride across the border. Intentional importation can also lead to introduction of rabies to different areas – I don’t mean intentionally importing rabies (people do… Continue Reading
