Abstract
293 blood samples collected randomly from I101 cattle (34.5%), 87 Sheep(29.8%) and 105 goat (35.8) from 12 villages in 3 districts (Bachit, Ganawuri and Riyom) of Riyom LGA were examined. The total number of male animals was 113 (38.5%) while female were 180 (61.4%) for Trypanosoma infections. 39(34. 51%) of the males were cattle, 32(28.3%) sheep and 42 (37.17%) goat. While 62(34.4% of the Cattle were female, 55(30.5%) sheep and 63(35.0%) goats. The blood samples were analyzed for parasitaemia using a combination of blood (Thin, Thick and wet) film techniques and concentration methods. (Haematocrit centrifugation technique [HCT] and Buffy Coat method [BCM]). 21 (7.2%) of the total blood screened from the three districts were positive for both Trypanosoma vivax, T. congolense and T. theileri. The average packed cell volume (PCV %) for infected males and non-infected males is 21.4 ± 4.4 and 25.7 ± 5.0 while that of female is 18.6 ± 4.7 and 26.4 ± 11.6, respectively. T. vivax is higher 17(81%) in occurrence than T. congolense 3(14.3%) and T. theileri 1 (4.8%). An incidental low infection of microfilaria was found in cattle, sheep and goats in Bachit 7(6.3%) and Riyom 2(6.7%). Other details are discussed.
