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 Baylisascaris
pricyonis-infected raccoons (Procyon lotor) in Florida.
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
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).
