Prevalence of Bovine Trypanosomosis and Distribution of Vectors in Hawa Gelan District, Oromia Region, Ethiopia
Journal Title: Journal of Veterinary Advances - Year 2013, Vol 3, Issue 8
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. Buffy coat examination for parasitological study and deployed traps for the detection of vectors of Trypanosomosis were used. A total of 388 blood samples (176 in control and 212 in non-control kebeles) were examined. Parasitological findings revealed that the prevalence of Trypanosomosis was 9.1% in ‘’Mada Talila’’ whereas 15.1% in ‘’Gudina Wacho’’ though statistically significant difference was not observed (χ2 =3.197, p=0.07). The overall prevalence was 12.4%. Of the total infected cattle, 45.85% and 33.33% was T. vivax and T. congolence respectively (χ2=17.54; p=0.016). The mean PCV values of parasitaemic and aparasitaemic animals were 23.3 + 3.7 SD and 25.95 +3.9SD respectively (χ2 =0.932, p=0.007). About 20 mono-conical traps (8 in control site and 12 for non- control site) were deployed for 72 hours. A total of 1,428 flies were collected (11.9 fly/trap/day) tse tse and (10.2 fly/trap/day) Stomoxys, (0.9 fly/trap/day) Tabanus and (0.8 fly/trap/day) others which had significant difference (χ2=348.4; p=0.00). Finally, implementing control of trypanosomosis with an integrated approach is essential components for sustainable development and strengthens the settlement programs of people from drought vulnerable areas.
