Baylisascariasis T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=7030900 RD 2024/04/19 AB Baylisascariasis is a potentially serious form of larva migrans that is caused by larvae of the raccoon ascarid, Baylisascaris procyonis, a nematode found in 50% to 80% of raccoons in North America. It also occurs in raccoons in other countries, including Germany and Japan. B procyonis is a well-known cause of larva migrans in animals and is usually associated with central nervous system disease. Larvae of B procyonis have produced fatal or severe central nervous system disease in over 100 species of mammals and birds. Other Baylisascaris species, including B melis of badgers and B columnaris of skunks, are also potential causes of human disease.1
