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 then 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 were examined, 36 (9%)
were positive, out of which 26 (0.065%) had Trypanosoma
vivax and10 (0.025%)had T. congolense. The mean PCV of the infected animal is 19.36 and that of non
infected animal is 27.54, which indicates a significant difference between
these animals. Trypanosomosis is a fatal and economically devastating disease and
the major constraint to production by causing loss of the livestock. Therefore,
the better strategies to prevent this disease includes: avoidance of animals
from tsetse-infested areas, tsetse fly control by using different scientific
methods (such as, sterile insect technique, use of accaricides), prophylactic
use of trypanocidal drugs, keeping of trypanoresistant breeds and good
husbandry practice for the prevention of the disease.
