Description
Summary:Snakes of the genus Bothrops inhabit tropical forests in Central and South America and are important for the biomedical and pharmaceutical industries because of the chemical properties of their venom. They serve as either definitive or intermediate hosts for many parasitic helminths. The Marajó Island (Brazil) is the natural habitat of venomous snakes, Bothrops atrox and Bothrops marajoensis, which are often found around rural and peri-urban areas and are known to bite humans. Samples of helminths parasitizing the oral cavity, subcutaneous tissues, coelomic cavity, and intestine of four B. atrox from Marajó Island (Pará-Brazil) were collected. The specimens studied were taxonomically classified as trematodes of the species Stycholecitha serpentis, nematodes of the genera Eustrongylides and Camallanus and cystacanths of an acanthocephalan of the genus Centrorhynchus. The aims of the present study were: to record helminths found in B. atrox from the Marajó Island; to discuss their role as definitive, intermediate, or paratenic hosts; and to compile a list of helminths that have been recorded in snakes of the genus Bothrops of the Neotropical region. •New records of helminths in B. atrox were identified: S. serpentis, Eustrongylides sp., Camallanus sp. and Centrorhynchus sp.•Bothrops spp. can serve as definitive, intermediate, paratenic, and accidental hosts of different helminths.•Among the 47 described Bothrops species, helminthological data are available for only 14 species.
