Abstract

A cross sectional study was conducted in Didesa district of Oromia Regional State from November 2013 to June 2014 to determine the prevalence of trypanosomosis and tsetse density. Simple random sampling was used to select 556 cattle from the purposively selected four PAs for collection of blood sample. Buffy coat technique was used to determine prevalence of bovine trypansomiosis in the study area and trap was deployed for collection of tsetse flies. Blood sample was examined and it was found that 27 (4.86%) were parasitic positive. The prevalence was insignificant (P>0.05) in sex group, age, body condition score and between peasant association. But PCV between parasitemic and aparasitaemic is significant (p< 0.05).In this study the most common trypanosome species identified were T. congolense (17/27, 62.96%) followed by T. vivax (9/27, 33.33% and mixed T. vivax and T. congolense (1/27, 3.70%). The proportional prevalence of T. congolense is significantly higher (P=0.000) than the other trypanosome species. The mean PCV values recorded were 21.52% in parasitaemic and 28.49% in aparasitaemic animals with a statistical significant difference (P<0.05). About 40 traps were deployed for 48 hours (2 days) for collection of tsetse fly. A total of 557 flies were collected from a study area, of which the higher density was for tsetse fly 382 (4.90 flies per trap per day) followed by 137 Stomoxys, 32 Tabanus and 6 haematopta. Generally, this study showed that trypanosomosis is still present and becomes a constraint for livestock production of the study area. So control and prevention mechanisms must be continued to reduce prevalence of the disease and tsetse flies population.

Buffy coat technique was used to determine prevalence of bovine trypansomiosis in the study area and trap was deployed for collection of tsetse flies. Blood sample was examined and it was found that 27 (4.86%) were parasitic positive. The prevalence was insignificant (P>0.05) in sex group, age, body condition score and between peasant association. But PCV between parasitemic and aparasitaemic is significant (p< 0.05).In this study the most common trypanosome species identified were T. congolense (17/27, 62.96%) followed by T. vivax (9/27, 33.33% and mixed T. vivax and T. congolense (1/27, 3.70%). The proportional prevalence of T. congolense is significantly higher (P=0.000) than the other trypanosome species. The mean PCV values recorded were 21.52% in parasitaemic and 28.49% in aparasitaemic animals with a statistical significant difference (P<0.05). About 40 traps were deployed for 48 hours (2 days) for collection of tsetse fly. A total of 557 flies were collected from a study area, of which the higher density was for tsetse fly 382 (4.90 flies per trap per day) followed by 137 Stomoxys, 32 Tabanus and 6 haematopta. Generally, this study showed that trypanosomosis is still present and becomes a constraint for livestock production of the study area. So control and prevention mechanisms must be continued to reduce prevalence of the disease and tsetse flies population.
