Carbapenemase-producing E coli in a veterinary hospital

Posted in Cats, Dogs
New antimicrobial resistance challenges continue to emerge. In the veterinary field (especially in small animals), we have the advantage of seeing what’s happening in human medicine first, since that’s often an early warning system for what we’re going to encounter. We’ve seen a variety of resistant bacteria first became a problem in people, and then… Continue Reading

Raw diets and multidrug-resistant bacteria

Posted in Cats, Dogs
Back in 2008, we reported an association between feeding raw diets to dogs and shedding of cephalosporin-resistant bacteria in dogs (that makes me feel old… one of many things that does these days, I guess). It didn’t get too much attention at the time, since the main focus of the study was on Salmonella, the… Continue Reading

High pressure pasteurization of raw pet food diets

Posted in Cats, Dogs
Raw diets have been in the news a lot lately because of Salmonella contamination. It’s not surprising at all since bacteria like Salmonella, E. coli, Campylobacter and Listeria are expected to be found in raw meat (that’s why we cook it). We know that dogs and cats fed raw meat are at increased risk of… Continue Reading

Raw pet food and human illness

Posted in Cats, Dogs
Human health risks from raw pet food (either from exposure to pathogens in the food or in the feces of pets eating the food) are known to exist but they’re not well characterized. We know that dogs fed raw meat-based diets clearly have increased risk of shedding various pathogens, particularly Salmonella and multidrug resistant E.… Continue Reading

Move Over mcr-1. You’re Old News.

Posted in Other animals, Other diseases
Recent identification of mcr-1, a gene that makes bacteria resistant to colistin (an antibiotic of last resort) raised a lot of concern. Now, there’s another one to be worried about, as a related gene, mcr-2 has been identified (Xavier et al, Eurosurveillance, July 2016). In this study, 105 colistin-resistant E. coli from calves and piglets… Continue Reading

Cat hoarding and E. coli

Posted in Cats
Cat hoarding has been in the news in the Toronto area a few times lately. Multiple incidents of serious cat hoarding have been identified in the past month, involving large numbers of cats being kept in horrible conditions. It’s not hard to see how cat hoarding can create infectious disease challenges. I can’t see how… Continue Reading

Petting zoo pathogens

Posted in Other animals
The 15 cm of snow that fell last night is as good of an indicator as any that agricultural fair season is over in this region. But, planning ahead is important (and often not done well with fair petting zoos), so it’s never to early to make a plan for next season. Petting zoos can… Continue Reading

E coli outbreak and dog risks

Posted in Dogs
I’ve had a few (well… more than a few) calls about potential risks to animals from the large Canadian E. coli O157 beef recall. The main concern is for dogs that are fed potentially contaminated raw meat that has been recalled, but there is also potential for exposure through cross-contamination if people in the household… Continue Reading

Petting zoo E coli: Wales

Posted in Other diseases
It’s perhaps a good sign for public health when I don’t tend to come home from a local fair and write a rant about the sorry state of the petting zoo. Around here, things seem to have improved at most events over the past few years, probably largely because of the efforts of local public… Continue Reading

NDM-1 in a cat

Posted in Cats
When bacteria containing NDM-1 (New Delhi metallobetalactamase 1) were first identified a few years ago, I talked about it during presentations as something bad that’s coming our way. NDM-1 is an enzyme that gives the bacteria that possesses it resistance to a huge range of antibiotics, to the point that few or no viable treatment… Continue Reading

Petting Zoo E coli outbreak

Posted in Other animals
It’s been a while since I wrote about petting zoos. Part of the reason is that the state of petting zoos in this area has improved quite a bit over the past few years, so I haven’t been coming home from fairs or other events with a need to vent. However, improvements are not universal, and… Continue Reading

Pet food (beef) recall: Canada

Posted in Dogs
The Canadian Food Inspection Agency (CFIA) and the Public Health Agency of Canada (PHAC) have issued warnings about frozen beef pet food made by Surrey Meat Packers of Cloverdale, BC. The Beef Pet Food consisted of frozen 500 g blocks of beef (presumably raw) sold between October 8 and 23, that may contain E. coli… Continue Reading

Seagulls, beaches and bad bugs

Posted in Other diseases
Just as I’m getting ready to go on vacation (that will hopefully involve some time on the beach), I read an article in the latest edition of Emerging Infectious Diseases about seagulls and beaches as reservoirs of multidrug-resistant E. coli (Simoes et al 2010). In this study, the researchers collected seagull poop from beaches in… Continue Reading

Boil water advisories: What to do with dogs?

Posted in Dogs
Here’s a reader’s question: "Our local water authority here on the East Bay of RI has issued a "boil water" alert because of the presence of e-coli as found in a routine test. My question is:  Do we need to boil dogs’ and cats’ drinking water as well? Seems that they eat the worst stuff… Continue Reading

Petting zoo outbreak investigation continues

Posted in Other animals
The investigation into a large E. coli O157 outbreak linked to a UK petting zoo continues, and the number of potentially exposed people is astounding. There are a couple of reasons that I write a fair bit about petting zoos, and they are highlighted here: the potential for exposure of a large number of people and the… Continue Reading

Testing petting zoo animals

Posted in Other animals
I received the following comment in response to a recent E. coli O157 and petting zoos post, and thought that it merited a post of its own. "Why doesn’t the petting zoo owners have a fecal swab sample taken from each animal in the petting zoo and submitted for STx PCR screen testing.  If a… Continue Reading

Verotoxigenic E. coli in petting zoo animals: UK

Posted in Other animals
I’ve written several posts about petting zoos, mainly about the potential negative aspects, although I still think they’re valuable if run properly. A major concern with these events is exposure of people to zoonotic infectious diseases, particularly harmful bacteria that can be carried by healthy animals. One of the more common pathogens that causes disease… Continue Reading

E. coli outbreak at a petting zoo

Posted in Other animals
The latest edition of the CDC’s Morbidity and Mortality Weekly Reports describes an E. coli O157:H7 outbreak associated with a petting zoo. The outbreak, which occurred at a day camp in Florida in 2007, involved 7 infected individuals. Two children were hospitalized. The same E. coli strain affecting the people was found in the stool… Continue Reading

Possible E. coli O157 infections from dogs

Posted in Dogs, Other diseases
Escherichia coli (E. coli) O157 is a particularly important bacterium that can cause very serious disease in people, including diarrhea and a severe kidney disorder called hemolytic uremic syndrome (HUS). Infection in people typically results from ingesting the bacterium from contaminated food products.  The main reservoir of E. coli O157 is in the intestinal tract… Continue Reading

Sharing E. coli with your dog

Posted in Dogs
A recent study, published in the American Journal of Veterinary Research, investigated the relationship of E. coli bacteria in people and their pets. This study reported a number of interesting findings: When they compared the molecular fingerprints of E. coli from people and pets, they were the same 10% of the time. This means that E. coli is… Continue Reading

Raw meat feeding revisited: what are the risks and benefits of raw diets for dogs?

Posted in Dogs, Salmonella
Feeding raw meat diets to dogs is a very controversial issue. Some proponents passionately advocate these diets (e.g. the BARF diet) based on vague and unproven recommendations. Opponents cite various studies showing that pets fed raw meat (not surprisingly) have high carriage rates of potentially harmful bacteria such as Salmonella, and reports of diarrhea or nutritional… Continue Reading
