     The Sulawesi black macaque (Macaca nigra) is an endangered species endemic to North Sulawesi, Indonesia, where populations are limited to fragmented areas of protected forest. As part of an ongoing study to evaluate potential threats to its health and survival, we conducted a survey of intestinal parasites in the population of black macaques at the Tangkoko Nature Reserve. Two hundred sixty-five fecal samples were collected from three known social groups between May and September of 2004 and 2005. Samples were preserved in 10% formalin and modified polyvinyl alcohol (PVA) and analyzed by ethyl acetate concentration and trichrome staining to identify parasites. Preliminary findings indicate the presence of Balantidium sp., Entamoeba sp., Ascaris sp., and Trichostrongylus sp. These parasite taxa are not species specific and are found in both human and nonhuman primates. In combination with the results of an evaluation of human samples collected in the local community, these data will be used to compare parasitic infection among macaque social groups that differ in their level of contact with the human population.
