The Waraos indigenous populations of the Lower Delta suffer from lack of optimal health services that allow them to diagnose and prevent enteroparasitosis. Objetive: to determine the prevalence of intestinal parasites (PPI), frequency and diversity of species, with emphasis on commensal flagellates. Methods: we studied 51 patients of the Warao ethnic group (21 females and 30 males) aged between 2 months and 68 years, who underwent coproparasitological examinations, with the techniques of 0.85% saline solution, Lugol and Kato’s technique. Results: a 100% PPI was obtained, where the diagnosed protozoa were: Endolimax nana (58.8% of the samples analyzed), Blastocystis sp. (56.9%), Entamoeba histolytica / Entamoeba dispar (41.2%), Entamoeba coli (29.4%), Iodamoeba butschlii (25.5%), Pentatrichomonas hominis /Trichomonas hominis (17.6%), Giardia lamblia /Giardia intestinalis (15.7%), Chilomastix mesnili (11.8%), Balantidium coli (2%) and Entamoeba hartmani (2%). The helminths found were: Ascaris lumbricoides (25.5%), Trichuris trichiura (5.9%) and Uncinarias sp. (2%). Conclusion: the PPI and the frequency of Pentatrichomonas hominis and Chilomastix mesnili are among the highest reported for Venezuela in recent years, indicators of the difficult health situation of this ethnic group.
