Capnocytophaga questions keep coming in. I guess that’s good in some ways, because I usually get a lot of blank stares when I mention that bacterium. A recent article about the risks of Capnocytophaga and exposure to dog saliva includes some good information about the topic, but the statements below highlight some issues:
It’s important
Every couple of months there’s a news report about a person with infection caused by the dog-associated bacterium Capnocytophaga canimorsus. Most of these reports don’t get too much attention, but every once in a while they get picked up pretty widely, resulting in another round of questions about this strange bacterium. It’s a bit
A few sentences into a Washington Post article entitled “A dog bite sent him to the ER. A cascade of missteps nearly killed him”, I was thinking, “This sounds like a pretty typical Capnocytophaga canimorsus infection. I wonder if this guy lost his spleen earlier in life.”
It turns out that was true.
Every year or so, there’s a new wave of publicity/paranoia about the risks associated with dogs licking people. Often, it follows a study of bacteria that can be found in the mouths of dogs. It leads to a combination of balanced reports, sensational reports and defensive responses.
What is the concern?
Dog’s mouths are
Capnocytophaga canimorsus is a bit of an obscure bacterium. When I talk about it to veterinary or physician audiences, I’m usually met with blank stares – not surprising, since it’s not really mentioned in veterinary or medical school, from what I can tell. It’s a rare cause of infection, but a nasty one. The fact
OK…time to get back to work writing. A couple weeks of conference organizing and uncountable Ebola calls are hopefully winding down, so back to the neglected blog.
This bug is an obscure one that I write about regularly: Capnocytophaga canimorus. It’s found in the mouth of most dogs, so people are commonly exposed to
“Animal-loving grandmother died from rare infection after her pet dog licked her hand and bacteria spread into her bloodstream.” For me, the first thing I think of when I hear that is Capnocytophaga canimorsus (to which most people respond “Capno-whata cani-whatsis?”).
It’s a tragic but textbook example of what this common dog-associated bacterium
That’s a great title that I can’t take credit for. A colleague (and regular supplier of papers for blog posts) Dr. Stephen Page send me a paper from the Journal of Clinical Microbiology with a more convoluted title “The Capnocytophaga canimosus isolate that caused sepsis in an immunosufficient man was transmitted by the large pine
I write about Capnocytophaga canimorsus regularly… disproportionately so, since it’s a rare cause of disease in people. However, though rare, when disease does happen it’s usually serious, and cases illustrate some important basic concepts that apply more broadly to other zoonotic diseases from pets.
The title of this post is from the latest edition of
I’m not a big fan of the title of a paper in the latest edition of the Canadian Journal of Infectious Diseases and Medical Microbiology…”Pets are ‘risky business’ for patients undergoing continuous ambulatory peritoneal dialysis” (Yahya et al 2013), even though it’s an interesting paper that actually takes a reasonable
