Aspectos ecológicos dos nematóides parasitos de Crotalus durissus terrificus Laurenti, 1768 (Ophidia, Viperidae), em Juiz de Fora, Minas Gerais, Brasil

Resumo

The aim of this work was to evaluate the qualitative and quantitative aspects of the nematode populations and community parasitizing Crotalus durissus terrificus maintained in semi-extensive breeding system, in Juiz de Fora, Minas Gerais, Brazil. For this 12 snakes were sacrificed and their intestine, stomach, lung, heart, liver and kidneys were examined. Among the examined snakes, 66% were found parasitized by at least one nematode species. The recovered nematodes were Kalicephalus costatus costatus and Kalicephalus inermis inermis in the stomach and intestine, Ascaridia sp., Travassoascaris sp., Hexametra sp., Ophidascaris sp. in the intestine and Rhabdias labiata in the lung. In accordance with the prevalence of each species Kalicephalus inermis inermis (58,3%), Kalicephalus costatus costatus (33,3%) and Rhabdias labiata (33,3%) were considerate secondary species, while Ophidascaris sp. (25%), Ascaridia sp. (16,6%), Hexametra sp. (8,3%), Travassoascaris sp. (8,3%), were considerate satellite species.
