More Pasteurella in the news

Posted in Cats, Dogs
The Canadian Journal of Infectious Diseases and Medical Microbiology has been good, recently, for a zoonotic disease article or two. The latest edition has a report of Pasteurella multocida infections of prosthetic joints (Lam et al. 2015). Pasteurella multocida is a bacterium that’s commonly found in the mouths of dogs and cats, and can cause… Continue Reading

Miscellaneous dog bite studies

Posted in Dogs
Dog bites continue to be a major cause of injury, especially in kids. Here are a few recent papers with some interesting information on this topic. A review of hospitalizations from dog bites in Ireland (O Suilleabhain et al. The Veterinary Journal 2015) had a few noteworthy findings: There were 3164 hospitalizations during the study… Continue Reading

Out of bounds, out of luck

Posted in Dogs
From CTVnews.ca "A Brazilian [soccer] player was taken to a hospital for an anti-rabies shot after being bitten by a police dog during a match. The incident happened in the second half of a first-division game between Democrata and Tupi on Sunday in the Minas Gerais state regional championship. Democrata striker Joao Paulo was bit… Continue Reading

Groundhog zoonoses?

Posted in Other animals
According to Groundhog Day lore, if the groundhog sees its shadow, you’re in for six more weeks of winter. If it doesn’t spring is around the corner. So, what does it mean when the critter draws blood? Sun Prairie, Wisconsin residents will find out this year, after Jimmy the Groundhog bit the town’s mayor. After… Continue Reading

Skunk + late vaccine + inflexibility = dead dog

Posted in Dogs
A Brockton, MA dog was euthanized after being bitten by a rabid skunk, because of a combination of the skunk’s rabies diagnosis, a relatively minor lapse in the dog’s vaccinations, and regulatory inflexibility. The ten-year-old Schnauzer cross was bitten in its own yard, and the skunk was subsequently caught, tested and diagnosed as rabid. Clearly,… Continue Reading

Another Capnocytophaga infection in a healthy person

Posted in Dogs
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 it.… Continue Reading

Casual cat causality

Posted in Cats
The credit (or blame) for the alliteration goes to colleague and frequent blog material supplier Dr. Stephen Page. It relates to an article in the prestigious medical journal Lancet (Kagihara et al. 2014) entitled “A fatal pasteurella empyema.” The article describes the case of a 60-year-old man from Honolulu who was admitted to hospital in… Continue Reading

Monkey bites and rabies quarantine

Posted in Other animals
"A monkey was placed under a six-month quarantine on Tuesday after it reportedly bit a woman at a Beaumont restaurant on Sunday…" Oh, where to start… Why do people feel the need to have monkeys as pets? I realize that they’re fascinating critters, but is it in the best interests of the monkey and the… Continue Reading

Attack of the marauding pine weevil

Posted in Other animals
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… Continue Reading

Boo Boo gets pardoned, but so much for stress relief

Posted in Other animals
Let’s put this one in the "smart people doing stupid things" file. Some well-intentioned people at Washington University in St. Louis thought they’d help relieve stress during exam time by bringing in a petting zoo – that unfortunately included "Boo Boo" the biting bear. As you can likely guess, problems ensued. 18 students sustained skin-breaking… Continue Reading

Raccoons in the bed

Posted in Other animals
There’s been some controversy in the past regarding allowing pets to sleep in or on the bed. I don’t get too worked up about it, since I think it’s very low-risk in terms of disease transmission for most pets and households, but a variety if reasons for prohibiting this practice have been given. I haven’t… Continue Reading

Rat bite fever…who’s to blame?

Posted in Pocket pets
A couple months ago, I wrote about a family suing PetsMart over a case of rat bite fever in a child. Now, a San Diego family is suing PetCo after their ten-year-old son died of the same infection.  Rat bite fever is a bacterial infection caused by Streptobacillus moniliformis, and it is almost always associated… Continue Reading

Cat bite infections (and dumb headlines)

Posted in Cats
It’s a scary sounding headline: “Cat Bites Pose Risk Of Infection As 1 In 3 Patients Bitten Hospitalized; Teeth Inject Bacteria Into Joints, Tissue” and it cites a research article from the Mayo Clinic in the Journal of Hand Surgery (Babovic et al 2014). Cat bites are nasty. The mouth of any cat harbours thousands… Continue Reading

Dog bite deaths, US, 2000-2009

Posted in Dogs
A recent high profile dog-bite death in the US has refocused discussion on bites and their causes. Co-incidentally, a paper in a recent edition of the Journal of the American Veterinary Medical Association (Patronek et al 2013, Co-occurrence of potentially preventable factors in 256 dog bite-related fatalities in the United States (2000-2009)) also addresses this… Continue Reading

Rat bite fever…who’s liable?

Posted in Pocket pets
A Colorado family is suing PetsMart and a rat supplier after their son developed rat bite fever (RBF), following a bite from a newly acquired rat. Lawsuits seem to be increasingly common after zoonotic infections, which is probably more of a reflection of an increasing tendency for people to sue, not an increasing occurrence of… Continue Reading

“An unwanted gift from man’s best friend”

Posted in Dogs
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… Continue Reading

Capnocytophaga Info Sheet

Posted in Dogs
We’ve just posted a new info sheet about Capnocytophaga.  One member of this bacterial group in particular, Capnocytophaga canimorsus, makes the news periodically because it can cause devastating infection in some individuals, like the Ottawa woman who lost three limbs after one of her own dogs accidentally bit her.  This kind of severe infection, which… Continue Reading

Keeping kids safe around pets

Posted in Dogs
One of our most frequent pieces of advice on W&GB when it comes to kids is to always make sure they are supervised when they are around pets.  This is important for at least two major reasons, one being avoiding potential high-risk contacts when it comes to infectious disease transmission (e.g. face-to-mouth, hand-to-bum), and the… Continue Reading

New bugs, same story

Posted in Dogs
A colleague recently let me know about an article in the journal Infection Ecology and Epidemiology entitled “Human wound infectious caused by Nesseria animaloris and Neisseria zoodegmatis, former CDC Group EF-4a and EF-4b" (Heydecke et al 2013). These are new bugs to me… The article outlines an effort to characterize these bacteria from people with… Continue Reading

US Rabies update

Posted in Dogs
ProMed-mail usually posts a monthly recap of rabies cases in the US. The most recent one (like most of them) doesn’t have anything too astounding, but it provides some good reminders. Skunk attacks baby A five-month-old baby that was outside in a car seat was bitten in the face several times by a skunk. The… Continue Reading

Dogs aren’t always the biters….

Posted in Dogs
Dogs have had some bad PR lately because of some high-profile bites and bite infections in people. So, in the spirit of fairness, I’ll write about a dog as a victim of an attack… from a cat. A paper in a recent edition of Veterinary Dermatology (Banovic et al 2013) describes necrotizing cellulitis in a… Continue Reading

Another dog-eats-toe story

Posted in Dogs
It’s maybe a sad statement that reading about someone whose diseased toes were gnawed off by their dog doesn’t shock me anymore. It’s not an everyday event but it’s far from rare. An Indiana man learned about this the hard way when he woke up thinking his dog was licking his toes, when in fact,… Continue Reading

Beware the mongoose

Posted in Other animals
I’ve been bitten lots of times, some on the job (including the last dog I saw when I was in general practice) and some off (including a dog down the road a couple of years ago). Fortunately, I haven’t suffered any serious consequences. That’s what happens most of the time. However, bad things can and do… Continue Reading
