RESUMO

The intestinal helminthes of the otter Lontra longicaudis (CARNIVORA, MUSTELIDAE) were studied. The fecal samples were collected in a creek (Ribeirão Cachoeira) situated in a forest fragment of Atlantic forest, and in a pond located in the Notredame house complex, both in the municipality of Campinas, Sousas district, São Paulo state, Brazil. The aim of the present study was to associate, through the intestinal parasites survey, trophic and behavioral aspects of L. longicaudis with the acquisition of parasites. The Faecal samples from each place was processed and analyzed individually, using the qualitative routine faecal methods: spontaneous sedimentation (HOFFMAN et al,. 1934) and Willis (WILLIS, 1921). From total 39 samples collected in Ribeirão Cachoeira creek, 22 were positive for eggs and /or larvae of helminthes (56,4%). In the Notredame house complex pond, samples from 29 total faecal samples collected, 13 showed positive results for eggs and /or larvae of helminthes (44,8%). Seven morphological types of helminthes eggs and two types of Nematode larvae were observed. Among the eggs, the most prevalent in the creek (54,5% trematode; 22,7% Strongyloides) and in the pond (46,2% trematode; 46,2% Strongyloides) were trematode egg and Strongyloides sp. egg. One of larvae found was of Strongyloides sp, type which was the most prevalent one (54,5% creek and 15,4% pond). This is the first occurrence of Strongyloides sp in neotropical otters.
