Canine heartworm (Dirofilara immitis) is a nasty parasitic infection of dogs that’s relatively rare in Canada, but it’s still a concern because of how severe it can be and because treatment isn’t easy. It’s transmitted by mosquitos (we have lots of those), but transmission is also influenced by temperature (which varies a lot
H5N1 Influenza in a Sheep
When it comes to food safety risks with H5N1 influenza, we know it’s a problem with raw (unpasteurized) milk from cattle, so I often get asked if it’s a concern with milk from other animals, such as goat’s milk. It’s a good question. My typical response has been that we really don’t know. There haven’t
Sorting Out H5N1 “Non-Negative” Raw Pet Food
It’s fair to say that raw pet foods have clearly been source of H5N1 influenza infections in cats, some of which have been fatal – even though sometimes it’s impossible to make a definitive link between the food and infection because of when and how the infection occurred, and what could or could not be
H5N1 Flu and Pet Food Safety
A recent opinion article in the Washington Post about how to protect cats from H5N1 influenza includes some good considerations, but alongside some bad information. It’s prompted me to write a bit about pet food preparation and how it does (and does not) affect the presence of infectious pathogens (but please keep in mind while
Reminder: Canine Culture Interpretation Changes and Guidance
Over a year ago, I wrote a few posts about changes to Clinical and Laboratory Standards Institute (CLSI) veterinary antimicrobial susceptibility testing guidelines. When a bacterium is grown in a lab and tested for susceptibility to different drugs, the lab looks to these CLSI guidelines to determine whether they should consider the bug susceptible
Dientamoeba fragilis in Dogs and Cats
I get variations of this question not uncommonly from veterinarians:
A client just came in and said they/their kid was diagnosed with Dientamoeba fragilis infection and their physician said to test/treat their dog. What should I do?
On one hand, it’s nice to see physicians thinking about animal exposures. On the other hand, it sometimes
Antiviral Resistance in Cats, Part 1: FIP Drugs
We don’t talk a lot about antiviral resistance in animals, particularly compared to antibacterial resistance, primarily because we don’t use antivirals a lot in animals – but we do use some.
When we use any anti-infective medication, we have to think about the risks of resistance developing to that medication, and how we can try
Cats and H5N1 Flu: More on Household Transmission Concerns
Details have now been released about the information that was briefly posted then removed from the US CDC website a couple weeks ago regarding suspected household transmission of H5N1 flu to and from cats. It’s great to have more details, but (as is common with emerging diseases) the full story probably raises more
Antimicrobial Prophylaxis in Animals: A Primer
If I asked 100 random people on the street “should we be giving antibiotics to healthy animals?” I’m pretty sure most or all of them would say “no.“
That makes sense in a lot of ways. We should save antimicrobials to treat sick individuals (especially people), and we shouldn’t use antimicrobials in
Another Raw Pet Food Recall for H5N1 Influenza After More Cat Deaths
The Washington State Department of Agriculture and the Oregon Department of Agriculture have issued a public health alert because of H5N1 influenza virus contamination of another brand of raw pet food, following the deaths of two more indoor cats from separate households linked to consumption of the pet food.
Details are sparse, but
