The keeping of small ruminants is a common practice in most urban and peri-urban areas in Africa, despite its illegality. This study was undertaken to determine the prevalence of endoparasites in sheep and goats kept by farmers in Kisumu Municipality, Kenya. Faecal samples were collected from 66 sheep and 60 goats, from different areas in the municipality. The helminth and coccidia species were identified and the level of infection compared between age, sex, body condition and area of origin. The prevalence of various types of parasites in sheep and goats were respectively: strongyles 80%, 90%; Strongyloides spp 5%, 13%; Trichuris spp 0%, 2%; Fasciola spp 37%, 36%; Paramphistomum spp 30%, 12%; Moniezia spp 21%, 16%; Coccidia 35%, 48%; Entamoeba spp 87%, 77%; Balantidium coli 2%, 3%; and Giardia spp 10%, 10%. Majority of animals excreted either 2 or 3 parasite types, while only a few sheep had 4 different parasite types. A relatively higher number of animals had heavy infections with strongyles (mean EPGs of 1253 and 1108 in sheep and goats, respectively), while for other helminths and coccidia most animals had light infections. Although the adults had higher levels of infections with trematodes, young animals had higher infections of the other types of parasites. Apart from trematodes and coccidia, male animals had higher prevalence and intensity of the other parasites. Sheep with poor body condition were significantly associated with higher mean EPGs of strongyles while in goats it was Moniezia spp. The association between the prevalence and intensity of the parasites and the independent factors are discussed. The occurrence of parasites with zoonotic significance (Fasciola spp, Entamoeba spp, Balantidium coli, and Giardia spp) is also discussed in the light of livestock farming in urban areas.
