Some gastro-intestinal tract parasites in wild De Brazza’s monkeys (Cercopithecus neglectus) in Kenya

Abstract

Fresh faecal droppings of wild group of De Brazza's monkeys (Cercopithecus neglectus), earmarked for translocation, were collected between January and July 1998. The samples were analysed using direct smears, ether-sedimentation and the Harada-Mori culture techniques for gastro-intestinal tract parasites (GIT). Two species of helminths and three of protozoa were detected. Entamoeba coli was found in all 40 samples screened from 11 monkeys. Entamoeba histolytica was detected in 71.8% of the total samples screened, Streptopharagus spp. in 12.8% and Strongyloides spp. and Balantidium coli each in 7.7% of the samples. E. histolytica and Streptopharagus spp. were most prevalent in faecal samples of juveniles while Strongyloides spp. and B. coli were mostly found in adult females. This, to our knowledge, is the first report of GIT parasites in a wild population of De Brazza's monkeys and our results are baseline. Copyright 2002 Elsevier Science B.V.
