The aim of this study was to collect information on trypanosomiasis as government and international donors funding for area wide survey has decreased. It is also to determine the prevalence of Trypanosomosis in slaughtered animals at different periods at the beginning (May), peak(August) and after (November) the rainy season. A total of 634 samples were collected and parasitologic ally examined using standard Trypanosome detection technique (STD) and concentration methods (HCT and BCM) for parasite detection. Physical examination of animals was carried out at slaughter. The overall infection rate was 2.2% while infection rate in males (2.7%) appeared higher than females (1.5%). The trypanosome species observed were T. congolense (50%), T. brucei (21.4%), T. vivax (14.2%) as single infections and T. congolense/T. brucei (7.1%,) and T. congolense/T. vivax (7.1%) as a mixed infections. The infection rates at the beginning (3.8%) appeared higher than the infection rates after (2.5%) and the peak (0.4%) of the rainy season. The packed cell volume of the infected (23.1±1.9) appeared significantly (p<0.05) lower than the packed cell volume of control (36.5±1.1). Also, it was noted that 142 (22%) of sampled animals were grossly emaciated and 57% of the animals found positive were emaciated and weak. This survey does not reflect the true prevalence but rather it provides significant information on the upsurge of tryp anosomosis. © 2011 Knowledgia Review, Malaysia.
