A coprological survey of parasites in white-faced capuchins (Cebus capucinus) from Sector Santa Rosa, ACG, Costa Rica.

Neotropical primate parasitology has been dominated by studies of howler monkeys (Alouatta spp.), whereas the literature on the parasites of other platyrrhines is relatively sparse. We analysed the faeces of white-faced capuchins (Cebus capucinus) in a Costa Rican tropical dry forest and recovered 8 parasite taxa (Filariopsis barretoi,Giardia duodenalis, Strongyloides sp., Prosthenorchis sp., a spirurid nematode, a subulurid nematode, a strongylid nematode and a cestode). F. barretoi and Strongyloides sp. were the most prevalent parasites and were recovered from 84 and 76% of the sampled individuals, respectively. Individual capuchins were infected with an average of 1.89 parasite species. Capuchins host a diverse suite of parasites belonging to several taxonomic groups (Nematoda, Cestoda, Acanthocephala, Protozoa) and including species with direct and indirect life cycles. Many capuchin parasites are transmitted through the consumption of invertebrate intermediate hosts making diet a critical component of capuchin-parasite ecology. This study represents the most intensive parasitological survey of wild capuchin monkeys to date.
