title: Patterns of infection by intestinal parasites in sympatric howler monkey (Alouatta palliata) and spider monkey (Ateles geoffroyi) populations in a tropical dry forest in Costa Rica.
abstract: In primate populations, endoparasite species richness and prevalence are associated with host traits such as reproductive and social status, age, sex, host population density, and environmental factors such as humidity. We analyzed the species richness and prevalence of intestinal parasites in two sympatric primate populations, one of Alouatta palliata and one of Ateles geoffroyi, found in a tropical dry forest in Costa Rica. We identified three species of intestinal parasites (Controrchis sp., Trypanoxyuris sp., and Strongyloides sp.) in these two primate species. We did not find any differences in species richness between the primate species. However, the prevalences of Controrchis sp. and Trypanoxyuris sp. were higher in Alouatta palliata. Similarly, males and lactating females of Alouatta palliata showed higher Controrchis sp. prevalences. We did not observe any differences in parasite richness and prevalence between seasons. Infectious diseases in endangered primate populations must be considered in conservation strategies, especially when defining protected areas.
