New World Screwworm (NSW) is a nasty parasitic infestation (with a very high ick factor) that’s back on the radar in North America, re-emerging after several decades of highly successful control and eradication efforts that had pushed its northern reach back as far as Panama. It has now made to back as far as northern
The other day, I did a half-hearted tick drag while walking Ozzie in our back field (yes, I know that’s strange, but let’s move on…). It was far from a professional job – just me dragging a blanket through the field as we walked, but it did the job. It quickly picked up a tick
I remember the first case of fly myiasis (aka fly strike, maggot infestation) in general practice. I was a very new grad called to look at a lamb owned by someone who had a few sheep. The complaint was that the lamb wasn’t doing well. It was laying down when I arrived and I grabbed
Tritrichomonas blagburni (formerly T. foetus) is a frustrating cause of diarrhea in cats. This parasite causes chronic diarrhea that will most often ultimately resolve on its own, but it can take months (or longer). During that time, most cats are largely healthy but with very messy feces (and they’re infectious). Some cats do feel
A couple of days ago, I mentioned that Jason Stull and I have done a scoping review of human Baylisascaris procyonis (raccoon roundworm) infections. The paper is published in the Canadian Veterinary Journal, but won’t be open access until October, so I’ll provide a preview of some of the findings here. Here’s a
Our emerging concerns about Rocky Mountain Spotted Fever (RMSF) in Long Point, Ontario, have led to a variety of questions from veterinarians and dog owners. (It’s also led to a lot of rumours, and sorting out what’s real illness vs internet chatter and hype is tough – but that’s another story.)
We’re still trying
I’ve heard of a few possible cases of Rocky Mountain Spotted Fever (RMSF) in dogs in Ontario in the past week. It’s pretty preliminary information, but it’s relevant to both dog and human health so it’s worth getting some information out about it now. At least one case was a pretty solid diagnosis: Rickettsia rickettsii
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
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
