Vivax) revealed significant (p=0.000, F=25.8) difference in PCV values were observed. Likewise, the Bonferroni multiple comparisons test indicated the existence of significant difference (p=0.000) in the PCV value between negative group and positive group for T. congolense (p=0.000). From 90 traps deployed for three consecutive days at 6 kebeles in three districts, a total of 328 flies were caught. Of these, 37 (11.28%) belong to Glossina pallidipes, the remaining were 193 (58.84%) Tabanus and 98 (29.87%) Stomoxys. The overall apparent tsetse fly density was 0.14 flies/trap/days (F/T/D).

A cross sectional study was conducted in and around Kemissie, Dawa Cheffa District to estimate the prevalence and identify possible risk factors for the disease in the study area. Animal identification based on age, sex, breed and body condition score and management system of the study animals were taken into account followed by coprological examination for the presence of the developmental stages of parasites or parasite in naturally infected cattle. For this purpose, four hundred and five randomly selected animals were examined during the study period out of which 75 (18.5%) were found positive for schistosomiasis based on fecal examination. Variation together with age and sex of animals did not show statistical significance (P>0.05) in the disease occurrence. However, the prevalence of the disease was highest in young animals (23.14%), followed by adults (17.61%) and least in old animals (15.49%). On the other hand, statistical significant association (P<0.05) was seen with the variation of breeds, body condition score and management systems in the disease occurrence. In conclusion, relatively moderate prevalence (18.5%) was recorded in and around Kemissie and based on the results obtained, recommendations were forwarded.

A cross-sectional study was carried out to determine the prevalence of cattle trypanosomosis and assess the distribution of its vectors in Gimbo and Guraferda districts of Kaffa and Bench Maji zones, respectively, in Southern Nations, Nationalities and Peoples' Regional State (SNNPRS), Ethiopia from November 2011 to March 2012. Simple random sampling technique was used to select 490 local zebu cattle from purposively selected three peasant associations in Gimbo and four peasant associations in Gurafereda districts. Blood samples were examined for trypanosmes by the buffy coat technique (BCT) after determining the packed cell volume (PCV) and traps were employed for collection of tsetse. The overall prevalence of cattle trypansomosis was 14.5%. The prevalence varied between the two districts, that is, Gimbo (9.2%) and Guraferda (19.6%). Trypanosoma congolense was the predominant species in the area (62%) followed by T. vivax (28.2%). Statistically significant (P<0.05) difference was observed in infection rate for the different trypanosome species, and in prevalence among animals of different body condition scores (p<0.001). However, no significant (P>0.05) difference was noted in prevalence rates among animals of the different age groups, sex and coat colors. The mean PCV per cent value of parasitaemic animals (21.31±5.070) was significantly (p<0.001) lower than that of aparasitaemic animals (27.00±5.097). Glossina pallidipes and Glossina fuscipes were captured in the study area with an overall apparent density of 3.73 flies/trap/day. In the light of these findings, integrated approaches involving both vector and trypanosome directed measures are suggested for effective management of the problem of cattle trypanosomosis in the study area.
