Parasitism is the most serious constraint causing continuous ill-health and lowered productivity in livestock in Tanzania and sub-Saharan Africa as a whole. This study was carried out in urban and peri-urban areas ofMwanza city and aimed to determine the prevalence ofparasitic infections in pigs kept by small holder livestock keepers. A random sample of14 urban farmers with a total of213 pigs and 14 peri-urban farmers with a total of155 pigs were selected. Faecal samples were collected from each pig. Ectoparasites were examined and their morphological characteristics recorded. Direct smear floatation and sedimentation methods were employed to detect endoparasites in the faeces. The prevalence of different types ofendoparasites in urban Mwanza city pigs were: Strongylid nematodes (11.7%) Entomoeba ssp (27.2%), Ascaris suum (1.8%) Balntidium coli (3.8%) and Coccidia spp (3.3%) and the only ectoparasites found was sarcoptic mange (1.4%). In the peri -urban area the endoparasites found were Entomoeba spp (51.6%), Strongylid nematodes (9.7%), Coccidia spp (5.8%). Ascaris suum (12.9%) Balantidium coli 20.6%) and Trichurus suis (3.8%) and the ectoparasites was sarcoptic mange (21.9%). Every piggery where samples were taken, the management system was assessed. The difference in the livestock management systems in the two areas clearly explains the observed high prevalence ofparasite infection in the peri-uban compared to the urban areas ofMwanza city. The negative impact ofthese parasites on livestock production and their public health importance -since some ofthem are zoonotic in nature- cannot be underestimated. The present study validates the need to bring awareness to the farmers and the public at large so that they may embark on cost effective development ofparasite control strategies.
