Baylisascaris procyonis roundworms are ubiquitous ascarid parasites of raccoons; prevalence of infection can reach 82% (3).
Their large population sizes and ubiquitous distribution make raccoons an important vector for parasites and diseases including distemper, rabies, and the roundworm
Baylisascaris procyonis (Mitchell et al.
Necrosis with microscopic lesions typical of
Baylisascaris species neural larva migrans was in the brain.
Nervous system diseases (n = 58) were caused by parasite migration (presumptive
Baylisascaris species), listeriosis, aspergillosis, West Nile virus, bornavirus, peripheral neuropathy and congenital malformation.
Raccoons were infected with the nematodes Arthrocephalus lotoris,
Baylisascaris procyonis, and Capillaria plica, the trematode Fibricola cratera, and the tapeworm Atriotaenia procyonis.

Contaminative potential, egg prevalence and intensity of

The most common nematodes to consider include Strongyloides stercoralis as part of a hyperinfection syndrome, Toxocara species or less commonly
Baylisascaris species as agents of visceral larva migrans, or other nematode worms that may involve the CNS such as Angiostrongylus and Gnathostoma species.
A slightly different test is used for diagnosing raccoon roundworm, called
Baylisascaris procyonis.
The threat I was telling you about was in raccoon feces containing the eggs of
Baylisascaris procyonis (a small intestine nematode parasite of raccoons).
Both species have been implicated in woodrat declines in the northeast United States from increased predation or exposure to
Baylisascaris procyonis (Balcom 1994; Balcom & Yahner 1996; McGowan 1993).
To the Editor:
Baylisascaris procyonis, an intestinal roundworm that infects raccoons (Procyon lotor), causes fatal or severe neural larva migrans in animals and humans (1,2).
