Raccoon Roundworm Infection (Baylisascariasis): a Zoonosis of Pediatric and Public Health Concern

摘要: The extraordinary heteroxenosity (ability to use many hosts in its life cycle) of Baylisascaris procyonis is particular concern not only wildlife biologists but also public health professionals and medical practitioners. To understand why there an increasing human risk for infection with B. procyonis, a discussion the biology behavior raccoons prerequisite subsequent discussions epidemiology, pathogenesis, clinical features, diagnosis, treatment. large ascarid parasite raccoons. biology, morphology, ecology are similar those other parasites carnivores, such as common canine roundworm, Toxocara canis. Humans become infected just these do accidental following inadvertent ingestion eggs containing infective larvae. Without question, biggest contributing factor poor response neural larva migrans (NLM) therapy treatment delay due failure add this zoonosis list differential diagnoses. problem urbanized exemplifies growing disconnect between public's conceptions about reality risks that uncontrolled can pose. Accurate assessment prevalence exposure would be significant value begin answer numerous questions remain epidemiology baylisascariasis.
