“…Several studies have reported Sarcocystis spp. cysts found in primates (Hernández-Jáuregui et al 1983, Mandour 1969, Karr & Wong 1975, Mehlhorn & Heydorn 1978, Kan et al 1979, Kimura et al 1987, Lane et al 1998, Yang et al 2005) however, to the best of our knowledge, this is the first report of Sarcocystis spp. infection in primates in Brazil.…”

The brown howler monkey (Alouatta guariba clamitans) is a primate species widely distributed in South America. Infections by protozoa are common in primates. However, studies on protozoa in primates in Brazil are scarce, so the goal of this study was to investigate DNA from the apicomplexan protozoa Neospora caninum, Sarcocystis spp. and Toxoplasma gondii in tissues of A. guariba clamitans. DNA extraction was performed on tissue samples from the heart, brain, liver, spleen, lung and intestine of six A. guariba clamitans from Santa Maria, Central Region of Rio Grande do Sul, Brazil. Conventional PCR was performed using 18S rRNA gene general primers for Apicomplexa and also specific primers to amplify Neosporaspp. and Toxoplasma gondii DNA. All animals were positive in the 18S PCR and the genetic sequencing confirmed the presence of Sarcocystis spp. DNA in the tissues of four animals belonging to at least two species (S. neurona and S. gigantea) and T. gondii DNA in the other two animals. One positive sample for T. gondii was genotypically characterized as atypical by the restriction fragment length polymorphism technique. N. caninum DNA was not detected in the tested samples. The presence of Apicomplexa protozoan DNA in the tissues of the six animals tested in this study highlights the importance of howler monkeys as maintainers of these pathogens in nature.
