The diagnosis was confirmed by 2 sequential enzyme-linked immunosorbent assay studies positive for B procyonis serum immunoglobulin G and by Western blot. Albendazole Albendazole (with or without corticosteroids) has been used in humans, but with no patients recovering and remaining neurologically intact. Baylisascaris procyonis, common name raccoon roundworm, is a roundworm nematode, found ubiquitously in raccoons, the definitive hosts.It is named after H. A. Baylis, who studied them in the 1920sâ30s, and Greek askaris (intestinal worm). When infective eggs of this roundworm are ingested by humans, Baylisascaris larvae hatch in the intestine and travel through the organs and muscles. Baylisascaris procyonis is a common and widespread parasite of raccoons in the United States and Canada. Baylisascaris procyonis, the raccoon roundworm, infects a wide range of vertebrate animals, including humans, in which it causes a particularly severe type of larva migrans. Baylisascaris larvae in paratenic ⦠The adult worms shed millions of microscopic eggs that are passed in the raccoonâs feces. The raccoon roundworm, Baylisascaris procyonis, is increasingly recognized as a cause of zoonotic visceral, ocular, and neural larva migrans and, in particular, of devastating encephalitis in young children. Skunks carry Baylisascaris columnaris, a similar species to B. procyonis. Baylisascaris infection in humans is uncommon but can be severe. Baylisascaris procyonis completes its life cycle in raccoons, with humans acquiring the infection as accidental hosts (dogs serve as alternate definitive hosts, as they can harbor adult worms and shed eggs). OVERVIEW: What every practitioner needs to know Baylisascariasis in humans is caused by infection with the raccoon roundworm, Baylisascaris procyonis. This is the larva migrans syndrome. It is an important cause of severe neurologic disease (neural larva migrans [NLM]) but also ⦠Baylisascaris procyonis is a roundworm of raccoons. Baylisascaris procyonis roundworms, a parasite of raccoons, can infect humans, sometimes fatally. With large raccoon populations occurring in many areas, the potential risk of human infection with B procyonis is high. Baylisascaris larvae in paratenic hosts can migrate, causing visceral larva migrans (VLM). Baylisascaris procyonis is found in the intestines of raccoons in North America, Japan and Germany.
