ARTÍCULO ORIGINAL/ORIGINAL ARTICLE PREVALENCIA DE HELMINTOS INTESTINALES DE UNA POBLACIÓN DE MONOS MAQUISAPAS SILVESTRES ATELES BELZEBUTH CHAMEK EN EL PARQUE NACIONAL DE MANU, PERÚ PREVALENCE OF INTESTINAL HELMINTHS FROM A POPULATION OF WILD SPIDER MONKEYS ATELES BELZEBUTH CHAMEK IN MANU NATIONAL PARK, PERU

The purpose of the present study is to establish the prevalence of intestinal parasites in a protected population of Ateles belzebuth chamek. Fecal samples were collected from 34 individuals in three social groups from one population at the Cocha Cashu Biological Station in Manu National Park, Peru. The samples were fixed in formalin (10%, 60 oC) and analyzed by the Direct method and the Ritchie test for helminths. For protozoans, the samples were preserved in polyvinyl alcohol fixative (PVA) and were smeared and then stained with Tricromica de Gomori. Laboratory analysis revealed that 76,4% (26/34) sampled individuals had parasites. Results included the identification of larvae or eggs of Strongyloides, Trichuris, Trypanoxyuris, strongyloid type, and one trematode of the Dicrocoeliidae, but not one species of protozoan.
