    Abstract:
    A total of 59 faecal samples from ranging Papio anubis (baboons) and another 41 from Cercopithecus aethiops (vervet) from the Rift Valley areas of Ethiopia were microscopically examined to determine the prevalence and species of major gastro-intestinal parasites of zoonotic importance. Faecal smears were prepared from fresh faecal samples, stained using modified Ziehl-Neelsen method and microscopically examined. About 3 gm of the dropping was also preserved separately in clean and properly labelled containers containing 10% formalin. The specimens were microscopically examined after formalin-ether concentration for ova, larvae, cysts and oocyst of intestinal parasites. The results of microscopic examination of faecal samples of baboons demonstrated the presence of Trichuris sp. (27.1%), Strongyloides sp. (37.3%), Trichostrongylus sp. (8.5%), Oesophagostomum sp. (10.2%), Schistosoma mansoni (20.3%), Entamoeba coli (83.1%), Entamoeba histolytica/dispar (16.9%), Blastocystis hominis (3.3%), Cyclospora sp. (13.3%) and Cryptosporidium sp. (11.9%). Likewise, the results of microscopic examination of faecal samples of vervets demonstrated the presence of Trichuris sp. (36.6%), Oesophagostomum sp. (4.9%), E. coli (61.0%), E. histolytica/dispar (24.4%), B. hominis (34.2%), Cyclospora sp. (22.0%) and Cryptosporidium sp. (29.3%). The presence of parasitic protozoa and helminths in baboons and vervets in the study areas is a high risk to human welfare because these non-human primates use the same water sources as humans and range freely in human habitats. An implication of such parasitic infection for the control programme is discussed.
