Imagine you’re a vet doing an exploratory abdominal surgery in a dog. You’re poking around in the belly and feel something abnormal. You grab it and as you pull it out of the abdomen to have a look, you see it’s a red tubular structure. As you continue to pull (and pull, and pull), it
International Canine Infectious Disease Map
A few times a week, I get questions like this from veterinarians:
- I have a canine patient from [name your country] and it’s sick. What diseases should I be aware of?
- I have healthy canine patient that was just imported from [name your country]. What diseases should I be aware of?
Or I get
Leishmaniasis in a Dog from California
Around here, infection in dogs caused by Leishmania infantum typically comes up in the context of imported dogs, particularly those from countries around the Mediterranean (e.g. Greece, Israel, Spain). This parasite is usually transmitted between a variety of mammalian species, including dogs and humans, by certain species of sandflies. We’re quite lucky here in Ontario
An Unusual Case of Echinococcus multilocularis in Manitoba
Last spring, we posted about a report of alveolar echinococcosis (AE) in a child in Quebec from 2018. This very serious parasitic infection is caused by the intermediate stage of the fox tapeworm, Echinococcus multilocularis (EM), which despite its common name is often also found in coyotes (including right here in southern Ontario
Oddball hookworm infection in a person
People sometimes get frustrated when I won’t say “absolutely, positively that cannot happen.” It’s not that I don’t understand or am afraid to make a decision, it’s biology. I can say something is “exceedingly unlikely to happen,” “not something I’d be concerned about” or
“there’s no evidence that’s a concern
Asian Longhorned tick and the role of canine (and feline) surveillance
As the Asian Longhorned tick (Haemophysalis longicornis) continues to spread in the US, we wait for it to make an appearance in Canada. This “exotic tick” was introduced to the US from Asia possibly a while ago, but was only first detected in 2017 in New Jersey. It has since clearly established itself
Resistant hookworms: An emerging problem?
In a presentation yesterday at the 2019 ACVIM Forum in Phoenix AZ, Dr. Ray Kaplan from the University of Georgia gave a somewhat scary talk about the emergence of multidrug-resistance in the hookworm Ancylostoma caninum.
Resistant parasites don’t tend to get as much attention as resistant bacteria, but they can present similar challenges.
Echinococcus multilocularis back in the news
Nothing 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.
PetsAndTicks… New for 2019
I 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
Echinococcus multilocularis in a child: Quebec
Echinococcus 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.
