Petland Campylobacter Outbreak Update

Posted in Dogs, Other diseases
The CDC has posted an update on the outbreak of Campylobacter infections in the US linked to puppies from Petland, a pet store chain. Here are the highlights: The case count is now up to 67, in 15 states (see map and graph of case occurrence below). The true number of infected people is unknown, since it’s reasonable… Continue Reading

Infections From Backyard Poultry

Posted in Birds, Salmonella
Hardly a week goes by that I don’t get a question (or a dozen) about backyard poultry. As more cities consider or enact laws allowing urban poultry, the debates about and around this issue increase. It’s also becoming a big business, with ample options for people to buy chicken coops (or high end chicken condos),… Continue Reading

Petland Puppy Campylobacter Update

Posted in Dogs
Here’s some follow up information from the recent (and probably ongoing) outbreak of Campylobacter infections linked to puppies purchased at Petland stores in the US: 55 infected people have been identified now. That’s probably just a fraction of the people who were truly infected, because of the number of steps that need to happen to… Continue Reading

More on H7H2 influenza in cats (and now a person)

Posted in Cats
A press release by the New York Department of Health and Mental Hygiene has provided some interesting new information about the recent H7N2 influenza outbreak in cats. This avian influenza strain is causing an ongoing outbreak in cats in shelters in New York, and human surveillance has been underway. Three-hundred fifty (350) people have been screened… Continue Reading

Raccoon Rabies – 1 Year Later

Posted in Rabies
It has been just over 1 year since the discovery of the first rabid raccoon in Ontario in over a decade, and the first rabid wildlife in the Hamilton area in over two decades.  Since then well over 4500 abnormal or “found dead” wildlife have been tested, and 253 animals carrying raccoon-variant rabies have been… Continue Reading

Vague Disease Warning in Dogs (and Cats?) in New Jersey

Posted in Cats, Dogs
A vague but potentially interesting report from New Jersey outlines a request for information about pet deaths in the area. The Cumberland County [New Jersey] Health Department is asking for the public’s help in collecting data on reports of what it calls “sudden and unusual illness” among dogs in the county. Perhaps the most interesting and… Continue Reading

Canine flu strikes again – Illinois

Posted in Dogs, Vaccination
Canine influenza has once again reared its ugly head in fairly spectacular fashion, this time in Bloomington, IL.  Apparently there have been numerous laboratory-confirmed cases, and also many suspected cases, and likely still more cases that have gone completely unreported.  It’s estimated that “hundreds” of dogs may have been affected already – it’s very difficult… Continue Reading

Rabies baits and feral cats

Posted in Cats, Dogs, Rabies, Vaccination
The incursion of raccoon rabies in the Hamilton ON area reached a total of 10 confirmed cases as of last week.  A map of the current MNRF control zone is available on the OMAFRA website.  This is the area where the Ministry of Natural Resources and Forestry (MNRF) has spread oral rabies vaccine (ORV) baits… Continue Reading

3 More Rabid Raccoons in Hamilton

Posted in Rabies
As they say, when you look you find. After a sick raccoon in Hamilton had an altercation with two dogs last week and subsequently tested positive for rabies, the Ministry of Natural Resources and Forestry (MNRF) tested an additional 14 raccoons and three skunks that were picked up by Hamilton Animal Services since then.  These… Continue Reading

Rabid Raccoon in Hamilton ON

Posted in Dogs, Rabies
Last week, a sick raccoon in Hamilton, Ontario got into an altercation with two bull mastiffs in the back of an animal services van.  The story quickly hit the media (and social media).  Because the raccoon was not acting normally (and was actually reportedly very aggressive), it was euthanized.  Because it also had direct contact with… Continue Reading

Ontario canine respiratory disease update

Posted in Dogs
Disease status Things seem to be slowing down. Whether that’s because of a true decrease in disease or “reporting fatigue” is a good question. However, I’m pretty certain that the outbreak is burning itself out in the areas that were most affected. Sporadic reports of sick dogs are still coming in from a few areas, but… Continue Reading

Ontario canine respiratory disease update

Posted in Dogs
Here’s a quick update about what we know… which really isn’t a lot more than yesterday. Case reports continue to roll in from different areas. I suspect the outbreak is burning itself out in Orangeville, but a few new cases are still being reported there. A few other clusters seem to be ongoing in different towns such… Continue Reading

Canine respiratory disease outbreak update

Posted in Dogs
As I’ve written about a couple times over the past few days, we seem to have increased canine respiratory disease activity in a few areas of Ontario. The first reports came from Orangeville (incidentally, the town where I worked as a veterinarian in general practice when I first graduated), based on information provided by an astute… Continue Reading

Canine respiratory disease precautions

Posted in Dogs, Vaccination
If you’re one of the many (many) people asking about what to do in the midst of a canine respiratory disease outbreak, or someone who just wants to know what to do to reduce everyday risk of CIRDC, here are some basic pointers: The microbes that cause respiratory disease in dogs are primarily spread by… Continue Reading

Increased canine infectious respiratory disease: Ontario

Posted in Dogs
Infectious respiratory disease isn’t exactly rare in dogs. A variety of viruses, bacteria and Mycoplasma can cause what we generically call canine infectious respiratory disease complex (CIRDC, formerly and still commonly called “kennel cough”). We see clusters of disease periodically and hear rumours of larger outbreaks, but usually there’s not a lot of additional information… Continue Reading

Small flocks, urban chickens and bird flu

Posted in Birds
Three poultry flocks in Ontario have been found to be infected with H5N2 highly pathogenic avian influenza (HPAI).  Under the direction of the Canadian Food Inspection Agency (CFIA), the lead agency when it comes to responding to federally reportable diseases like this, disease control zones have been established around the affected flocks, and movement of… Continue Reading

More on canine H3N2 flu

Posted in Dogs
Not surprisingly, I’ve been inundated with emails and calls about the H3N2 canine influenza outbreak that’s ongoing in the US. How far will it spread? Who knows? It’s always hard to predict what will happen with influenza viruses. The spread of the H3N8 canine flu virus was surprisingly slow and sporadic, and it has yet… Continue Reading

Vet clinics: Dealing with a canine flu outbreak

Posted in Dogs
Infection control in veterinary clinics has come a long way in the past few years. However, there are still many challenges, and new situations like the large H3N2 canine flu outbreak in the US Midwest raise more issues. Just like human hospitals, vet clinics need to be proactive to reduce the risk of flu virus… Continue Reading

Chicago canine flu strain shocker

Posted in Dogs
Cornell University, the Wisconsin Veterinary Diagnostic Laboratory and the National Veterinary Services Laboratory has indicated that the large, ongoing canine flu outbreak in the midwest US is being caused by an H3N2 influenza strain, not the expected H3N8 canine flu strain. Molecularly, the strain is closely related to H3N2 strains that are circulating in dogs in… Continue Reading

Equine outbreaks…EHV-1, glanders

Posted in Horses
Two cases of fatal equine herpesvirus type I (EHV-1) neurological disease have been confirmed in the Dickinson, Texas, area. Three more recent deaths are suspected to be associated with the virus as well. The horses were from two boarding stables that are currently under quarantine, as is a veterinary clinic. As always, there’s a need… Continue Reading

More hatching chick associated salmonellosis

Posted in Other animals
The salmonellosis outbreak in the US associated with hatching chicks continues to expand. The outbreak, ironically associated with Mt. Healthy Hatcheries in Ohio, has now sickened at least 344 people in 42 US states and Puerto Rico with a variety of Salmonella serotypes (S. Infants, S. Newport and S. Hadar). The outbreak shows no sign… Continue Reading

Never a simple story: West Nile in California

Posted in Other diseases
Orange County CA is currently experiencing a major outbreak of West Nile infection in people. Since January 94 cases have been confirmed, three of which were fatal, representing nearly a quarter of the 400 cases reported across the country so far this year. The number of cases of infection with a mosquito-borne virus like West… Continue Reading

Strangles and psychology

Posted in Horses
A couple days ago, I was talking to a vet who’s trying to manage a strangles outbreak on a farm. In many outbreaks, the biggest hassles are dealing with horse owners, not the disease itself. Strangles, infection by the bacterium Streptococcus equi subsp. equi, is a highly contagious disease but one that is relatively easy to… Continue Reading

Salmonella from bearded dragons…Canadian style

Posted in Reptiles
Not surprisingly (since bacteria don’t respect borders), the Salmonella Cotham outbreak in the US associated with bearded dragons has also affected people in Canada. Nine cases of human salmonellosis associated with this rare Salmonella strain have been identified, many with a link to bearded dragons. It’s not particularly remarkable, but should be yet another reminder… Continue Reading
