Prevalence of metazoan parasite infections in five species of Asian macaques.

Necropsy examination was performed on a total of 697 wild-caught macaques of five species. Helminthic parasites were found to be prevalent among these macaques, with species of Strongyloides, Oesophagostomum, Anatrichosoma, Trichostrongylus, and Gongylonema being the most common patent infections. Some of the larval stages of nematodes (ascarids, spirurids), cestodes (hydatid, Sparganum), and pentastomids grew into adults in appropriate definitive hosts upon experimental feeding, enabling species identification.
