The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. At least the other squirrels seem afraid of him and leave him alone to eat. Prevalence in raccoons is extremely high in the Northeast, Midwest, and on the West Coast, sometimes in excess of 80%. Baylisascaris procyonis is a common species-adapted ascarid (roundworm) found in the small intestinal tract of racoons in parts of North America, Europe, and Japan, and less commonly in South America. The adult worms are white to tan in color and range from about 10 to 20 cm (4-8 in) in length. Baylisascaris procyonis is considered to be an emerging helminthic zoonosis. What is Baylisascaris?. Heddergott M, Steinbach P, Schwarz S, et al. SUMMARY The raccoon roundworm, Baylisascaris procyonis , is the most common and widespread cause of clinical larva migrans in animals. This parasite also is zoonotic and has resulted in over 30 severe or fatal cases of larva migrans over the past 35 yr ( Kazacos 2001 ; Gavin et al. It typically results in fatal disease or severe sequelae, as in other animals. Historical invasion records can be misleading: genetic evidence for multiple introductions of invasive raccoons (. In other words, the parasite was not detected in the areas covered by the Luxembourg, Brandenburg, and Saxony genetic populations (Figure, panels B, C).
