Abstract: A total of 1528 stool samples were examined during a survey of intestinal parasites in 542 members of the Tapirapé ethnic group (279 females and 263 males), who live in the Brazilian Amazon region of Mato Grosso. Overall, 542 individuals from six indigenous villages were enrolled of whom 45 (8.3%) were positive for Hymenolepis nana based on analysis by microscopy of fecal concentrates. H. nana was more prevalent in male individuals (77.8%) as compared to females (22.2%). Moreover, males aged under 15 years have been associated with positivity for H. nana (P = 0.02). This study is the first report of the prevalence of H. nana in members of the indigenous Tapirapé ethnic group from the Brazilian Amazon.
