Abstract
A coprological survey of gastrointestinal parasites in wild Japanese macaques (Macaca fuscata), from 14 natural habitats was done. Ova of five nematode species (Trichuris trichiura, Strongyloides fuelleborni, Streptopharagus pigmentatus, Oesophagostomum aculeatum, andGongylonema species) and a worm of the cestode species,Bertiella studieri, were detected. Some differences found in rates of infection by sex were observed in the 14 areas. Differences based on age were found in only troops in which the infection rates ofStrongyloides fuelleborni, Streptopharagus pigmentatus, andTrichuris trichiura were higher in the juvenile monkeys. The number of parasite species was related to the geographical and climatic conditions of the habitat of the troop: troops living in areas cold in winter were infected by fewer parasite species than those in southern warmer areas.
