Infection with Baylisascaris procyonis roundworms is rare but often fatal and typically affects children. Baylisascaris procyonis, common name raccoon roundworm, is a roundworm nematode, found ubiquitously in raccoons, the definitive hosts.It is named after H. A.

They can survive hot or freezing weather and certain chemicals, remaining viable for several years. [ 46 ]: Prevalence (%), number of bears infected with B. transfuga eggs excreted in faecal samples divided by total number of bears examined. Disease risk is driven by environmental egg contamination which increases with raccoon density, worm intensity, and worm prevalence. Baylisascaris procyonis, the raccoon roundworm, inhabits the small intestine of raccoon, often in large numbers as in this case. The paratenic hosts often show significant signs of disease due to the larva that grows during its migration. The prevalence of eggs decreased at latrines, and larval infections decreased among intermediate hosts, indicating that baiting is effective. The adult worms are white to tan in color and range from about 10 to 20 cm (4-8 in) in length. Baylisascaris eggs are passed in feces and become active within a month.

Infection with Baylisascaris procyonis roundworms is rare but often fatal and typically affects children. Raccoons are the primary host. To develop a management technique for parasite eggs, we tested anthelmintic baiting. They can then be ingested by, and infest, a variety of other animals (including humans) that serve as paratenic hosts.
