The 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

Deworming wild and feral animals

Posted in Parasites
I 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

Raccoon roundworm reminder

An 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

Infection from raccoon to parrot

An article in the May/June edition of Canadian Vet Newsmagazine (a magazine, not to be confused with Canadian Veterinary Journal, a scientific journal), described an interesting case of an indoor pet bird acquiring an infection from a wild raccoon, despite no direct contact. The bird was an African Grey Parrot that was admitted to the… Continue Reading

Reducing risks with raccoon latrines

Posted in Other animals
An interesting paper in the journal Emerging Infectious Diseases (Page et al. 2011) describes an impressively large effort to study the effect of anthelmintic (dewormer) baiting on parasite contamination at raccoon latrines sites in Indiana. Raccoon latrines can be highly contaminated with various parasites, because raccoons congregate at these sites and use them as "communal… Continue Reading

Baylisascaris and dogs

Posted in Dogs
Recently, I was speaking with a physician who mentioned that a colleague has recommended that people with raccoons in their yard get rid of their dogs because of the risk of Baylisascaris procyonis. This parasite, also known as the raccoon roundworm, can cause severe neurological disease in people that ingest infective parasite eggs from the environment.… Continue Reading

Baylisascaris in Winnipeg

Posted in Parasites
There 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

Raccoon deterrents

Posted in Other animals, Parasites
We’ve written various posts about raccoons, raccoon latrines and concerns about the raccoon roundworm (Baylisascaris procyonis). I received a question today about how to keep raccoons from coming back after a latrine has been identified and cleaned. It’s a good question, and one without a simple answer.  I’ve looked through various sources and have found… Continue Reading

Raccoon latrines in Chicago

Posted in Other animals, Parasites
If you live in the suburbs of Chicago (or probably many other cities as well), chances are pretty good that you live close to a raccoon latrine. Raccoons like to defecate in specific areas (raccoon latrines) which can become highly contaminated with eggs of Baylisascaris procyonis, the raccoon roundworm. Human disease caused by this parasite… Continue Reading

Cleaning up raccoon latrines

Posted in Other animals, Parasites
Raccoon latrines are a major source of eggs of the raccoon roundworm, Baylisascaris procyonis.  Accidental ingestion of large numbers of eggs from these latrines can lead to a disease known as visceral larval migrans.  The most severe forms of this condition are known as ocular or neural larval migrans, which are damage to the eyes… Continue Reading
