Cryptosporidiosis is a rapidly emerging disease in the tropics. This is the first report of and other protozoan infections ( spp., and spp.) in wild primates that inhabit the natural forest of Sri Lanka. It is unclear if non-human primates serve as a reservoir for these parasites under certain conditions. A cross-sectional coprologic survey among 125 monkeys (89 toque macaques, 21 gray langurs, and 15 purple-faced langurs) indicated that was detected in all three primate species and was most common among monkeys using areas and water that had been heavily soiled by human feces and livestock. Most macaques (96%) shedding oocysts were co-infected with other protozoans and important anthropozoonotic gastrointestinal parasites (e.g., and ). The transmission of these parasites among primates in the wild may have important implications for public health as well as wildlife conservation management.
