PARASITOS GASTROINTESTINAIS DE Iguana iguana LINNAEUS, 1758 (SQUAMATA: IGUANIDAE) DA ZONA URBANA DE TERESINA, PIAUÍ, BRASIL

Studies on host-parasite relationships are one of the factors responsible for understanding the variations that occur in the population dynamics of vertebrate community structures. Infections by parasites influence the control of the population of their hosts. The objective of the present work was to identify the parasitic fauna in Iguana-verde ( Iguana iguana ) of the urban zone in Teresina-PI. In total, 15 iguanas were captured, 06 on Maranhao Avenue and 09 in the UESPI regions. Oxyurid eggs were found by the method of Hoffmann and modified Willis-Mollay technique. The helminths found were the oxyurids: Ozolaimus cirratus in the large and small intestine of the parasitized iguanas and Ozolaimus megatyphlon only in the large intestine. In this work we report for the first time the occurrence of the genus Ozolaimus in iguanas piauienses. Maranhao Avenue is a highly anthropogenic place, consequently alters the native habitat of the animal, revealing the importance of these animals in their natural or less anthropogenic environment.
