Helmintos oxiuridae parasitos de Iguana iguana (Squamata, Lacertilia, Iguanidae) procedentes do Brasil

Abstract

The results of a study on nematode fauna occurring in wild iguanas (Iguana iguana) from Brazilian Northeast (Alagoas and Maranhão) and Central-west (Goiás and Mato Grosso) areas were presented. Six adult iguanas, three males and three females, were necropsied and the digestive system removed to examination. All the iguana specimens were heavily parasitized. The helminths diagnosed were: Ozolaimus cirratus in the cecum and colon of five iguanas; Ozolaimus megatyphlon in cecum, colon and rectum of three iguanas; and Alaeuris vogelsangi in the small intestine, cecum, colon and rectum of five animals. Two larvae of Ozolaimus sp. were recovered from the pyloric region of the stomach of one iguana. The three diagnosed species of nematodes were reported for the first time in the Brazilian Central-West region.
