Impacto da urbanização sobre a fauna helmíntica em Alouatta, em 2 reservas biológicas, na região metropolitana de Porto Alegre - RS

Abstract

The fragmentation of howler monkeys (Alouatta) habitat to make room for the urban environment, allows the spread of zoonotic diseases. The objective of this study was to verify the occurrence of helminth eggs in the feces of Alouatta guariba clamitans in 2 biological reserves located in Porto Alegre - RS. Lami and São Pedro, respectively, presented eggs of gastrointestinal parasites of the superfamilies Strongyloidea; Oxyuroidea, Trichuroidea and Rhabdiasoidea. The results demonstrate that in the more fragmented habitat there is a greater risk of parasitic infection together with multiparasitism, since the samples from the Lami neighborhood showed greater variability of parasites.
