By Scott Weese on Posted in Cats,Dogs,Horses,Other animalsDr. Theresa Tam, Canada’s Chief Public Health Officer, has issued a spotlight report: Handle with Care: Preserving Antibiotics Now and Into the Future. There’s nothing too surprising in it, which in a lot of ways is the point. Addressing antimicrobial use and resistance isn’t rocket science, it’s application of a lot of basic, common sense measures.… Continue Reading
By Scott Weese on Posted in HorsesA common limitation of studies or case reports of zoonotic pathogens or infections is that they are one sided – they often just discuss the human case(s), or they just report carriage of a pathogen in animals. Case reports of human infections often only go as far as saying something along the lines of “this… 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 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 HorsesIt’s that time of year. Mosquitoes have been annoying me for months (I get bitten multiple times a day where I live, even with repellent), but now they’re becoming a bigger issue. While mosquitoes bite all season, some of the diseases they transmit are only a significant risk at certain times of year. One high… Continue Reading
By Scott Weese on Posted in Cats,Dogs,HorsesHere are some pictures of the latest tick maps from PetsAndTicks.com. As expected, tick reports are down this time of year, but they’re likely to increase a lot in September as we see the next big wave of ticks come out looking for food.… Continue Reading
By Scott Weese on Posted in Horses,Other diseases,VaccinationBeing an equine vet in some parts of Australia (namely Queensland) is scary… to the point that people are leaving equine practice or refusing to treat certain cases. That’s because of Hendra virus, a bat-associated virus that infects horses and which can spill over into people. It hasn’t infected many people, but it is most… Continue Reading
By Scott Weese on Posted in Birds,HorsesWhen I talk about infection control (or infectious diseases, in general), I emphasize the need to avoid tunnel vision. Sometimes, we run into situations where someone says “that animal tested negative for [name your bug], so we don’t have anything to worry about.” Well, no. It means you (probably) don’t have to worry about that… Continue Reading
By Scott Weese on Posted in Cats,Dogs,HorsesAs part of our recently launched PetsAndTick.com information and tick-tracker website, we are offering a pilot tick identification program. We will be offering identification of ticks that are removed from animals (non-human animals, to be specific). The program will complement our tick-tracking efforts and help gather more information about expanding tick ranges and incursions of… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Other animalsAfter a particularly miserable spring here (to put it mildly), it’s finally warming up, and the snow’s almost gone. That’s the good news. The bad news is that ticks are also going to start coming out and looking for food – that means looking for animals (including us). I assume there will be lots of… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,RabiesHere are updated versions of the US rabies maps from yesterday’s post, with the addition of some more data. Pennsylvania’s looking more biohazardous now but that’s because we got a lot more data for that state. If we get more data from other areas, the maps will be updated accordingly.… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Rabies,VaccinationWe track a few different diseases, both for research and for general education, including rabies. The maps below provide an overview of rabies in dogs, cats and horses in the US in 2017. It’s not a complete representation of cases, since we don’t have access to everyone’s surveillance data. It’s compiled through monitoring various reports… Continue Reading
By Scott Weese on Posted in Animals,Birds,Cats,Dogs,Horses,Other animals,Other diseases,Pocket petsThe post below is reproduced from CANresist.blog. It applies equally for veterinary medicine. I think most people buy into the concept of fossil fuels being finite resources. Someday, they’ll run out or logistics and cost of extraction will make them impractical. Accordingly, we’re thinking about ways to reduce and improve use (to delay the end of the… Continue Reading

By Scott Weese on Posted in HorsesTwo Ontario horses have recently been diagnosed with West Nile virus infection, prompting the equine health advisory below from the Ontario Ministry of Agriculture Food and Rural Affairs. That’s not too surprising, as now is the typical time of year that we start seeing this mosquito-borne infection in Ontario. West Nile numbers in both humans and… Continue Reading
By Scott Weese on Posted in Horses,Other diseasesI’ve had this paper from One Health (Chan et al 2017) on my “to blog” pile for a while, since it’s an interesting story. Like any case report, it’s a bit of an oddball infection, and not likely indicative of a major or new risk. However, there are often a few good general take-home messages from… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Other animalsIt’s commonly been stated that it’s important to finish your course of antibiotics (whether “your” refers to a person or animal), as a means of reducing the risk of developing antibiotic resistance. That’s never made much sense to me, since more antibiotic exposure is more likely to lead to a risk of resistance emerging. However,… Continue Reading
By Scott Weese on Posted in Dogs,Horses,Other diseases,ParasitesGuest Blog by Dr. Michelle Evason DVM DipACVIM, and current PhD student researching Lyme disease in dogs Recently, an interesting article on pet ownership and human tick risk was published (Jones et al, Zoonoses and Public Health 2017). The study looked at risk factors for “tick encounters” in people living in Lyme disease endemic states in the… Continue Reading
By Scott Weese on Posted in Horses,Rabies,VaccinationIf a horse comes into the hospital at this time of year and has some difficulty standing, incoordination and mild fever, the first thing on my list of likely causes is probably equine herpesvirus type I (EHV-1) infection. Next would be West Nile virus encephalitis. However, we consider all sudden onset neurological disease cases in… Continue Reading
By Scott Weese on Posted in Dogs,HorsesGuest blog by Dr. Michelle Evason, DVM DipACVIM (as well as current PhD student and coordinator of our Lifetime Lyme Study) In 2014, the Public Health Agency of Canada (PHAC) initiated a 3-year marketing campaign (news, advertisements, social media, collaboration with Parks Canada to post signage, etc.) to try to raise the general public’s awareness and… Continue Reading
By Scott Weese on Posted in Cats,Dogs,HorsesTo continue the map-posting binge that I’ve been on lately, Public Health Ontario has just posted their updated Lyme Disease Risk Areas map for 2017. For comparison, you can still also access the 2016 map too, and you can see that the risk areas have indeed expanded somewhat, particularly in Eastern Ontario. The estimated risk… Continue Reading
By Scott Weese on Posted in Cats,Dogs,HorsesOur online Pet Tick Tracker continues to receive lots of submissions, so here are some interesting maps showing some of the preliminary information compiled so far. The maps show where the ticks are being reported, but remember that they’re not necessarily reflective of the true overall picture, since it depends on who is reporting and who isn’t reporting.… Continue Reading
By Scott Weese on Posted in Cats,Dogs,HorsesOver the years, we’ve tried a variety of new approaches to promote awareness (among the public, veterinarians and others) and to collect relevant research information. Some (like this blog) have taken on a life of their own and exceeded our expectations. Some didn’t go very far. Our most recent initiative is the PetTickTracker, a website designed… Continue Reading
