Our objective was to determine the occurrence of intestinal parasites in Azuero howler monkeys (Alouatta coibensis trabeata) in the high area of the Province of Herrera. Howler monkeys have a high number and diversity of parasites, however, information on parasitosis has not been characterized. 43 samples of fecal matter were collected, which were preserved in 10% formalin, and subsequently analyzed by direct observation coprological methods and the Ritchie and Willis-Molloy techniques, to determine the presence of intestinal parasites from monkeys in the area of study, during the months of October 2019 to January 2020. The intestinal parasites found were Strongyloides sp. (34%), Entamoeba sp. (22%), Ascaris sp. (18%), Trypanoxyuris sp. (16%) and Controlchis sp. (11%). No significant differences were observed in terms of parasite prevalence during the months of monitoring. The results suggest that the parasitic loads are determined by particular conditions of the habitat, feeding and behavior of the monkeys within the reserve.
