ABSTRACT

Intestinal parasitism is caused by helminth and protozoan species and, depending on the pathogenicity of the etiological agent, can cause the death of the infected one. High rates of parasitism are often related to the pollution of water, soil and food. This research had the objective to perform a parasitological survey on the Xerente indigenous population of the Salto village in the city of Tocantínia, Province of Tocantins, Brazil. A total of 104 fecal samples were examined from volunteers of both genders and different age groups. For the parasitological diagnosis, the samples were submitted to the techniques of Hoffman, Pons and Janer, Ritchie and Kinyoun. The overall prevalence for parasites was 89.42%. The prevalence by species were: Ascaris lumbricoides (63,46%), Hymenolepis nana (20,19%), Ancylostomatidae (13,46%), Strongyloides stercoralis (7,69%), Trichuris trichiura (7,69%), Entamoeba coli (31,73%), Entamoeba histolytica/dispar (14,42%), Giardia lamblia (8,65%), Endolimax nana (7,69%) and Iodamoeba butschlii (4,81%). This research contributed to know the identity of the parasites incident among the Xerente population and guided the appropriate drug intervention.
