Prevalence of Bovine Trypanosomosis and Distribution of Vectors in Hawa Gelan District, Oromia Region, Ethiopia

Abstract

A study was conducted in tse tse controled ''Mada Talila'' and non- controlled (''Gudina Wacho'') of ''Hawa Gelan'' district commencing September 2011 to December 2011. The objectives of the study were to determine the prevalence of Bovine Trypanosomosis and to assess distribution and apparent density of vectors. The Buffy coat technique was used for the detection of parasites and deployed traps for the detection of vectors of Trypanosomosis were used. 388 blood samples from cattle (176 in control and 212 in non-control kebeles) were examined. Parasitological findings revealed that prevalence of Trypanosomosis was 9.1% in ''Mada Talila'' whereas 15.1% in ''Gudina Wacho'' though statistically significant difference was not observed ( =3.197, p=0.07). The overall prevalence was 12.4%. Of the total infected cattle, 45.85% and 33.33% was 2
