By Scott Weese on Posted in Deworming,Dogs,ParasitesEchinococcus multilocularis, a small tapeworm with a big name, is causing big concerns in Ontario, an area that was until recently considered free of this parasite. This tapeworm is normally found in the intestinal tract of wild canids (e.g. coyotes, foxes) and can also infect dogs. That itself isn’t a problem, since the intestinal form… Continue Reading
By Scott Weese on Posted in Cats,Dogs,RabiesI spend a lot of time answering questions about rabies exposures, and sometimes trying to clear up misinformation. Rabies is a very important infectious disease but in many regions (like here) it’s fortunately rare in domestic animals and people. However, rarity can breed complacency or lack of (or loss of) knowledge. That creates problems when… Continue Reading
By Scott Weese on Posted in DogsTularemia is a nasty bacterial disease. The bug that causes it, Francisella tularensis, is a category A bioterrorism agent (along with things like anthrax, botulism, plague, smallpox and Ebola virus). It’s classified as that because it’s highly transmissible and causes serious disease, so it’s something you definitely don’t want. The bacterium circulates in the wild,… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Other animals,Rabies,VaccinationAs is typical for this time of year, the annual US rabies report has been published in the Journal of the American Veterinary Medical Association (Ma et al, 2018). Here are some highlights: 4454 rabid animals were identified across the country. This is certainly a marked underestimate of the actual number since most rabid animals… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationNo, we haven’t changed to a cooking blog, I’m talking about bites of the canine variety. I can’t think of any specific data that would show it, but I wonder whether bites are more common around the holidays, with disrupted schedules and more visitors (and a potential midnight intruder in a red suit). The rabies-related… Continue Reading
By Scott Weese on Posted in Dogs,Other diseasesI’m once again prepared to call Ontario (and Canada) canine influenza-free… for now, at least. The latest cluster, associated with another importation of the virus from China, seems to have been contained. The last new positive case was identified October 30, with the likely date of exposure being October 23. We are now beyond the… Continue Reading
By Scott Weese on Posted in DogsI’ve been behind on posts so here’s a quick update: things seem to be going well in the latest Canadian H3N2 canine influenza outbreak. Here’s the rundown: After eradicating the last outbreak in the spring, cases were identified again in mid-October, associated with more importation of dogs from Asia. The last new positive dog was… Continue Reading
By Scott Weese on Posted in DogsThings have been quiet over the past few days. That’s good news (but always makes me a bit antsy, because I want to be sure it’s because there are no new cases vs we’re just not finding them). Documented infections have been confined to one region, with the exception of a dog that travelled out… Continue Reading
By Scott Weese on Posted in Cats,Dogs,SalmonellaWe’ve known for some time that there are human health risks from feeding pets raw meat-based diets. Most of the evidence of this has been anecdotal, as published reports have been sparse. A few better documented reports have started to appear, including the fatal E. coli O157 infection I wrote about recently. A few days… Continue Reading
By Scott Weese on Posted in DogsAs expected, a few more cases have been identified in the most recent cluster of canine influenza virus (CIV) identified in Ontario. So far, there are about 20 confirmed or suspected cases. To date, we’re still only finding cases that have a link to another infected dog or facility. That’s good news. If we start… Continue Reading
By Scott Weese on Posted in DogsClick here for an article from TheConversation.com by Dr. Katie Clow (of petsandticks.com fame… well maybe not “fame” quite yet, but the site’s getting more and more attention) about “How to avoid Lyme disease while ticks are hungry in the fall.”… Continue Reading
By Scott Weese on Posted in Cats,DogsHuman 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
By Scott Weese on Posted in DogsWhile we’re still working on sorting out and containing our latest Canadian outbreak of H3N2 canine influenza, we can look to the south to see the problems this virus is still causing. Flu is still active in a variety of locations in the US. The numbers reported are presumably a marked under-estimate, since it’s based… Continue Reading
By Scott Weese on Posted in DogsMore cases of H3N2 canine influenza have been identified in the province since the virus was re-introduction to central Ontario in the last week. That’s not surprising, since the start of any outbreak investigation is dedicated to figuring out the extent of the problem. Cases identified in the first few days or week reflect things… Continue Reading
By Scott Weese on Posted in DogsCanine influenza virus (CIV) has been re-introduced to Ontario, again in the Muskoka region. Variant typing for the latest case should be available shortly, but in all likelihood this is once again H3N2 CIV. More details will follow; however, dog owners and veterinarians in this region should be aware of the return of this highly… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,ParasitesHere’s a post by Dr. Katie Clow from our sister site, PetsAndTicks.com: Today, we received our 400th tick submission (actually, 401 to be exact). Does that sound like a large or a small number? Although there’s no real answer to that question, to me it seems like a pretty small number. At this time last… Continue Reading
By Scott Weese on Posted in Dogs,MRSA/MRSPMy email and phone have been lighting up over the past few days about news reports describing a study presented at a recent scientific meeting in San Francisco. I wasn’t there and the results aren’t published, so I don’t have a lot to go on, but here are some highlights from the news article on… Continue Reading
By Scott Weese on Posted in DogsThis week’s edition of the CDC’s Morbidity and Mortality Weekly Report has a summary of the 2016-2018 campylobacterosis outbreak linked to pet store puppies. Nothing is particularly surprising, but that doesn’t mean it’s not disappointing (or depressing). Click here for the complete article. Here’s a (relatively) brief summary: It all started when sequencing of Campylobacter jejuni… Continue Reading
By Scott Weese on Posted in Dogs,Other diseasesIt’s probably not actually a “new” bacterium but rather recognition of a species that we’ve been mixing up with something else, but regardless, a paper in the International Journal of Systematic and Evolutionary Microbiology (yes, that’s an actual journal) describes a new Staphylococcus species, Staphylococcus cornubiensis (Murray et al. 2018). Here’s what we know: The… Continue Reading
By Scott Weese on Posted in Cats,DogsNo, it’s not pets freaking out and killing people. It’s people staying in harm’s way during natural disasters because they can’t take their pets with them. I saw some data about this from Hurricane Katrina years ago, and while I can’t remember the exact number, an astounding number of deaths were associated with people who… Continue Reading
By Scott Weese on Posted in Dogs,Other animals,RabiesI realize headline writers are trying to attract attention, and sometimes they don’t know much about the content. As a result, some headlines are quite over the top, and that can freak people out. Here are some examples from the past couple of days: 4 year old girl catches life-threatening infection by trying on shoes… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other animals,Rabies,VaccinationHuman deaths from rabies are common in some developing countries (where tens of thousands die from canine rabies every year) but rare in developed countries. It’s an almost invariably fatal disease, but at the same time it’s almost completely preventable because of the quality of vaccines and post-exposure prophylaxis available. Getting those treatments to the… Continue Reading
By Scott Weese on Posted in Cats,DogsWhile ticks don’t care about political boundaries, researchers often do (or practical aspects dictate that we must). That doesn’t mean we can’t work together, though. A recent post at our related site petsandticks.com talks about the differences between US and Canadian tick submissions, and how US residents can submit ticks to the Show Us Your… Continue Reading
By Scott Weese on Posted in DogsCapnocytophaga 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 to… Continue Reading
