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,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 Cats,Dogs,ParasitesA post from guest blogger Dr. Katie Clow, reproduced from our sister site www.petsandticks.com. It’s summertime, and for most Canadians that means we’re taking some time off work to enjoy a little rest and relaxation. Maybe that’s a week at the cottage, or an adventure in another county. And if it’s a family trip, there’s… Continue Reading
By Scott Weese on Posted in Cats,Dogs,ParasitesNegotiating the world of antiparasitics for dogs and cats can be daunting. With the wide range of products, similarly named products with different ingredients and differently named products with the same ingredients, it’s hard to keep up. The Ontario Animal Health Network as put together some useful tables that outline antiparasitic products available in Canada… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Parasites,Salmonella,ToxoplasmosisI think I’ve covered this before (probably a few times), but the question keeps coming up so it can’t hurt to talk about it again: “Is freeze-dried raw pet food any different than fresh or frozen raw diets, from a microbiological standpoint?” We don’t have much pet food-specific research, but there’s little reason to believe… Continue Reading
By Scott Weese on Posted in Dogs,ParasitesIf you’d asked me a few years ago, I wouldn’t have said that’s a question I’d expect to get (daily). However, we’re in a different world tick-wise now, so it’s a common and understandable question, particularly because of our tick tracking efforts. The answer is no/possibly/maybe later. How’s that for a straight answer? We are… Continue Reading
By Scott Weese on Posted in Cats,Deworming,Other diseases,Parasites,ToxoplasmosisI’m not sure I wrote about it at the time, but last spring we adopted Rumple (technically Rumpelstiltskin, pictured below… rough life) from the Guelph Humane Society as part of their Barn Cat Adoption program. He quickly migrated from the barn and set up shop as a garage and deck cat (which also lead to… 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 Dogs,ParasitesSeveral news articles have been written lately about the recently-described cases of Echinococcus multilocularis infection in four people in Alberta. The cases of alveolar echinococcosis have occurred over the past 4 years, and raise significant concerns. Echinococcus multilocularis is a small tapeworm but it causes big problems. Why? It’s a potentially nasty parasitic disease that can act a lot… Continue Reading
By Scott Weese on Posted in Parasites,Rabies1) Pick up baby raccoons and take them away Rarely does this end well. It’s illegal in many areas (including Ontario). Raccoons don’t do well long-term in households for various reasons (their curious and destructive nature being a big one). And, they are potential sources of a number of zoonotic diseases (rabies being a big one but not… Continue Reading
By Scott Weese on Posted in Other animals,ParasitesI think petting zoos can be great. I’ve taken my kids to many and think they’re a great way for people to see and interact with animals they would not normally encounter. However, there’s always some risk, and petting zoos range from exceptionally well run to horrible. It seems like there’s been steady improvement over… Continue Reading
By Scott Weese on Posted in Dogs,ParasitesThe fox lungworm, Crenosoma vulpis, continues to be identified in dogs in Ontario. The attached map from WormsAndGermsMap shows the cases we know about. There aren’t many, but the issue of “rare vs rarely diagnosed” is important. As a relatively new (or newly identified) problem that requires specific testing, it’s easy for it to be… Continue Reading
By Scott Weese on Posted in Other animals,ParasitesThe US Geological Service isn’t the first thing that comes to mind when I think about publishers of zoonotic disease information (but what do I know?). If you’re looking for some holiday reading, the USGS has published a comprehensive overview of Baylisascaris larva migrans, a serious disease caused by Baylisascaris procyonis, the raccoon roundworm. This parasite… Continue Reading
By Scott Weese on Posted in Other animals,ParasitesThe August edition of Emerging Infectious Diseases has an interesting case report of Baylisascaris procyonis infection in a California man (Langelier et al. 2016). Baylisascaris procyonis, commonly known as the raccoon roundworm, is a parasite that is very commonly found in the intestinal tracts of raccoons. Massive numbers of parasite eggs can be found in… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Parasites,RabiesA few years ago, we launched WormsAndGermsMap to help track certain emerging and endemic diseases. Data are entered by participating veterinary clinics, surveillance programs and the WormsAndGerms team. While we certainly can’t capture every case, we do collect some interesting information about the presence of certain diseases. Using the “Report Filter” bar on the left, you can… Continue Reading
By Scott Weese on Posted in Cats,ParasitesHeadline writers have had a lot of fun over the past few years writing about toxoplasmosis and potential associations with neurological and behavioural disorders in people. Cats are the main natural host of Toxoplasma gondii, so “crazy cat lady” and other predictable headlines have ensued. But, what is the real risk? The answer is still… Continue Reading
By Scott Weese on Posted in Dogs,ParasitesAnother emerging disease we’ve been paying attention to lately is canine lungworm. Lungworm is a generic name for infection caused by one of a few different parasites that live in the respiratory tract. A variety of different lungworms can cause disease in different species, and there tends to be a lot of regional variation. Recently,… Continue Reading
By Scott Weese on Posted in MRSA/MRSP,Parasites,Salmonella,ToxoplasmosisPresentations from the 2015 Centre for Public Health and Zoonoses (CPHAZ) Symposium are now on YouTube on the Worms & Germs Blog channel. There is a wide range of talks, including topics such as West Nile virus, Lyme disease, salmonellosis, MRSA, Toxoplasma and various other zoonotic diseases.… Continue Reading
By Scott Weese on Posted in ParasitesI had a question the other day about roundworms in feral cats. Specifically, how do you deworm a group of cats that you don’t handle and may not be able to catch? There are a few possible approaches, from trapping and treating (oral or topical) to trying to get a dewormer into them via food.… Continue Reading
By Scott Weese on Posted in ParasitesAn article by Dr. Ann Britton of British Columbia’s Animal Health Centre (AHC) on the blog site healthywildlife.ca is another reminder of the perils of raccoon poop. Over a 2 year period, 17 raccoons were submitted to the AHC for necropsy, and 12 (71%) of them were infected with Baylisascaris procyonis, the raccoon roundworm. The… Continue Reading
By Maureen Anderson on Posted in ParasitesThe latest Worms & Germs infosheets are all about some common and not-so-common members of a particular group of parasites: tapeworms. There are a number of different groups and species of tapeworms that can infect pets, people, and other domestic animals, and sorting through which is which can be tricky, so we created a Tapeworms… Continue Reading
By Scott Weese on Posted in ParasitesHere is another guest blog, this time from the "worm-guy" Dr. Martin Nielsen of the Gluck Equine Research Center at the University of Kentucky. At the recent 9th International Conference on Equine Infectious Diseases (EIDC) in Lexington, Kentucky several sessions were focused on parasite control of horses. Drug resistant parasites are a world-wide problem in… Continue Reading
By Scott Weese on Posted in ParasitesDeworming has become a controversial subject. There are numerous opposing views, strong opinions and conflicts of interest that drive a lot of debate on the subject. There’s no argument that parasites can be bad for pets and some can pose a risk to people. There’s no argument that we want to reduce parasite burdens in… Continue Reading
By Maureen Anderson on Posted in ParasitesThere was another paper published in the August issue of the Canadian Veterinary Journal about Baylisascaris procyonis (roundworms) in raccoons, this time in Winnipeg, Manitoba (Sexsmith et al 2009). The study was actually undertaken after infection with B. procyonis larvae was identifed as the cause of death of several animals in the collection at the… Continue Reading
