Prevalence of Intestinal Helminthparasites in Rhesus Monkey(Macaca Mulatta) of Swoyambhu And Nilbarahi Area of Kathmandu Valley

Abstract

Thepresent study provides a base line data on faecal helminth parasites of Rhesusmonkey from Swoyambhu and Nilbarahi area. As a whole 200 samples werecollected. The faecal samples were examined by direct smear and concentrationmethods. In both the area the overall parasitization rate was 62%. Parasitization ratewas found higher in Swoyambhu (67%) than that of Nilbarahi (58%). The result ofthe microscopic examination of faecal samples of Rhesus monkeydemonstrated thepresence of Nematode (85.82%), Trematode (93.14%), Cestode (7.08%) andAcanthocephala (3.93%). Out of the total positive samples, single infection ofhelminth parasite was found to be 65.3%, double infection 24.40% and multipleinfections7.08%. Prevalence rate of zoonotically infective gastro-intestinal helminthwas found to be 83.46% and zoonotically non infective (16.53%). The species wiseprevalence rate of gastrointestinal helminth parasites were as follows: Starting fromthe highest prevalence percentage of Srongyloides fulleborni(42.5%), followed byDictyocaulus sp (7.87%), Taenia sp (7.08%), Oesophagostomum sp (6.29%),Trichuris ovis(4.72%),Capillaria sp (3.93%),Ostertagia sp (3.93%),Cooperiasp(3.93%), Prosthenorchis elegans (3.93%), Dicrocoelium sp ( 3.14%),Trichostrongylus sp (3.14%), Oxyuris sp (3.14%), Toxascaries leonina(3.14%),Trichuris trichura(2.36%),Ascaries lumbricoides(1.57%),Toxocara canis(1.57%)andChabertiasp(1.57%). All the genus and species of intestinal parasites are reported here for the first timefrom Rhesus monkey (Macaca mulatta) from Nepal whereasProsthenorchis elegansis reported for the first time in Nepal. This is not even reported from any other host.
