PINBOARD SUMMARY

A cross-sectional study was conducted from November 2010 to April 2011 to determine the prevalence of trypanosomosis and to identify the prevailing species of trypanosomes in cattle present in and around Nekemte. Blood sample were collected from ear vein of 400 cattle and examined using thin and thick smear method followed by Buffy coat examination. Anemic status was determined by Packed Cell Volume (PCV). Out of 400 samples examined, 36(9%) were positive, out of which 26(0.065%) had Trypanosoma vivax and 10(0.025) had T.congolense.Trypanosomosis was mostly observed in adult animals 30 (0.075%), out of which 23 (0.0575%) are T.vivax and 7(0.0175%) are T.congolense, but with lower rate in younger animals 4(0.01), out of which 3(0.0075%) are T.congolense and 1(0.0025%) is T.viavax. When observing in the sex categories the disease is frequently seen in female animals 22(0.055%),out of which 16(0.04) are T.vivax and 6(0.015%) are T.congolense. In male animals seen at lower rate of 14(0.035%), out of which 10(0.025%) are T.vivax and 4(0.01%) are T.congolense. The mean PCV of the infected animal is 19.36 and that of non infected animal is 27.54, which indicate a significant difference between these animals. Trypanosomosis is an economically devastating disease. Therefore, it is necessary to have a better strategy like avoidance of animals from tsetse-infested areas, prophylactic use of trypanocidal drugs and good husbandry practice for the prevention of the disease.
