In the first two parts of this series, I explained a lot of the changes that have been made to the CLSI veterinary antimicrobial susceptibility testing guidelines, specifically those related to staphylococci and Enterobacterales (which includes E. coli and friends). There’s less to say about Pseudomonas, but these changes will impact our

New CLSI Breakpoints For Veterinary Medicine: How to Interpret Results While Labs Are Updating Their Protocols, Part 2: Staph, Enterobacterales and Fluoroquinolones in Dogs
The Clinical and Laboratory Standards Institute (CLSI) has updated their main veterinary testing standards document: VET01SEd7E Performance Standards for Antimicrobial Disk and Dilution Susceptibility Tests for Bacteria Isolated From Animals, 7th Edition. Check out earlier posts for an overview of the relevant changes, and more specifics about the standards for staphylococci and chloramphenicol…
New CLSI Breakpoints For Veterinary Medicine: How to Interpret Results While Labs Are Updating Their Protocols, Part 1: Staph and Chloramphenicol
Yesterday, I wrote a post about a new version of CLSI’s Performance Standards for Antimicrobial Disk and Dilution Susceptibility Tests for Bacteria Isolated From Animals. There are some major changes in this update, and I sympathize with the diagnostic labs that now have to update their testing and reporting. It won’t happen overnight, because…
Updated CLSI Veterinary Susceptibility Testing Guidance: What Veterinarians Need to Know (Spoiler… This One Has Lots of Relevant Changes!)
Diagnostic testing is a cornerstone of veterinary medicine that helps us optimize patient care, but there’s a lot of science behind it that people often forget. We collect a sample, send it off for testing and magically get the results, often without putting a lot of thought into what happens at the lab. Labs (should)…
Let Doxycycline Off the Leash: No Need to Avoid It in Young Growing Animals
I spend a lot of time talking about antimicrobial misconceptions and dogmas. They are a big issue, because they often lead to unnecessary or excessive duration of antimicrobial use, use of more invasive routes of administration (e.g. intravenous over oral), or use of higher-tier antimicrobials than necessary.
I’ll just address one of these misconceptions today:…
Update: Canine Infectious Respiratory Disease (January 10)
This may be my last update on this topic in the short term (unless things change, of course).
The good news:
- Cases of canine infectious respiratory disease complex (CIRDC) around most of the US and Canada seem to be waning, if not back to normal. Since we have no formal surveillance, we have to rely
Bluetongue In a Dog
I’ll take a break from writing about widespread canine infectious respiratory disease complex (CIRDC) in North America to talk about a single case of a rare disease in a dog. Wageningen Veterinary Research has reported a case of Bluetongue infection in a dog in the Netherlands, a disease of significant consequence to livestock that’s…
Your Dog’s Social Network: Why It Matters
No, I’m not talking about a need for Facebook for Dogs. I’m talking about the interaction and contact networks that dogs have, which are important for understanding and mitigating infectious disease risks. Let’s use my dogs as an example.

Update: Canine Infectious Respiratory Disease (December 21)
There’s still not really a lot to report with the current canine infectious respiratory disease situation in North America, which is probably good news. As ever, we’re largely flying blind because we have no coordinated surveillance for canine infectious respiratory disease, so we’re try to figure out as much as we can through a…
Update: Canine Infectious Respiratory Disease (December 8)
Spoiler alert: there’s not a lot new to say about the ongoing situation with canine infectious respiratory disease in North America. Most of this I’ve said before. Talk seems to be dying down in a lot of areas, but whether that’s because there are fewer cases or people are just getting bored of talking…
