Abstract: A cross sectional study on camel trypanosomosis was conducted in Dello-Mena and Sawena districts of Bale Zone Oromyia Region, Ethiopia from September 2007 to June 2008. The study was carried out to determine the serological and parasitological prevalence of surra and to compare them in two areas of different ecological characteristics (wet and dry). Blood samples were collected from 619 camels and examined for the presence of agglutinating antibodies against T evansi using card agglutination test for trypanosomiasis (CATT/T. evansi), and a parasite detection buffy-coat method (BCM). The overall parasitological and serological prevalence of camel trypanosomosis was found to be 12.12% and 24.88%, respectively. Camels in Dello-Mena had a significantly higher serological as well as parasitological prevalance of surra than in Sawena district. Thus it was found that camels in riverine areas of Dello-Mena were more at risk of infection than herds in non-riverine areas of Sawena. There was a statistically significant difference (P<0.001) in the mean PCV of parasitologically positive and negative camels. However, the mean PCV of seropositive but parasitologically negative camels did not differ from the mean PCV of sero negative and parasitologically negative camels. More than 1/3 of the positive camels ill BCM were negative in CATT/T. evansi indicating the existance of non RoTat 1.2 T. evansi isolates from camels in Ethiopia. From the results of the present study if can be inferred that camel trypanosomosis is endemic in Dello-Mena and Sawena districts of Oromyia Region, Ethiopia where it demands further study on identification of the principal vector species responsible for transmission and investigating the potential for vector control.
