We detected protozoans including Blastocystis sp., Entamoeba coli, E. We examined 119 fresh fecal samples using standard coproscopical methods. We studied the parasites of savanna chimpanzees ( Pan troglodytes schweinfurthii) living in the Issa Valley, Ugalla (Tanzania). Gastrointestinal parasites of chimpanzees ( Pan troglodytes) have been studied extensively at several forested sites, but the parasite fauna of chimpanzees living in dry, open habitats is less well known. Understanding variability in patterns of parasite infections requires studies of multiple populations inhabiting a variety of habitats.
