ABSTRACT: Trypanosoma spp. infection is a problem in many tropical countries, infecting several animal species, including humans. The aim of the present study was to identify the Trypanosoma species in Neotropical primates from Rio de Janeiro state and compare the results with other reports both phylogenetically and geographically. Molecular detection was based on the 18 SSU gene. The sequences obtained in the PCR were sequenced and compared with others previously deposited in GenBank. These sequences were used to perform phylogenetic analysis and make a distribution map of primate species infected by Trypanosoma species in Brazil. Among 34 monkeys, five capuchin monkeys (Sapajus spp.) and one marmoset (Callithrix spp.) showed Trypanosoma spp. sequences in the same clade of Trypanosoma minasense and three capuchin monkeys’ sequences were in the same clade of Trypanosoma cruzi. The Atlantic Forest and the Brazilian Amazon are the regions with the highest frequency of studies about Trypanosoma spp. and variety of Neotropical primate hosts. These are areas that deserve attention regarding the conservation of biodiversity, but it also makes evident the lack of studies with Neotropical primates in other regions of the country, as well as multidisciplinary studies to better understand the host pathogen relationships.
