Nematode parasites generally found around the world. Research on intestinal parasitic nematodes in long-tailed monkeys ( Macaca fascicularis ) has been carried out in Cikakak Village, Banyumas Regency. The aims of the research was to find out the diversity and prevalence of Nematodes parasite on long tail monkey.

The results of the study found five types of intestinal parasitic nematodes classified as " Soil Transmitted Helminths " namely Strongyloides sp. Ascaris sp. Trichuris sp. Ancylostoma sp.

Parasitic nematodes in adolescent long-tailed monkeys are relatively similar to adult monkeys. The prevalence of long-tailed monkeys infected with parasitic nematodes is quite high at 40.5 ± 13.5. The prevalence of long-tailed monkeys in adolescence is higher than the prevalence of adult long-tailed monkeys, nematode infections in long-tailed monkeys in Cikakak Village are more single infections.
