Contagious bovine pleuro pneumonia is prevalent in almost all areas of Ethiopia and cause reduction to the livestock production and affect livelihood of small scale farmer which caused by MmmSc. Even though Contagious bovine pleuro pneumonia is prevalent in Ethiopia and large numbers of cattle are present in Dawo district there was no information about prevalence and risk factors of disease, there was no research conducted to detected molecules of disease from positive cattle and knowledge, attitude and practice of farmer in Dawo district of south west shewa zone, Oromia, Ethiopia. A cross-sectional study was conducted to determine prevalence and associated risk factor of CBPP, molecular detection of MmmSc from positive cattle and to evaluate knowledge, attitude and practice of farmer on occurrence of disease. Four hundred cattle were randomly selected from five purposively selected peasant associations and serum sample were transported to National animal health diagnostic center for diagnosis the presence of antibody against MmmSc antigen. The collected data were analyzed using SPSS version 20 software. From 400 cattle 72(18%) individual animals and from 144 herds examined 54(37.5%) herds were positive against MmmSc. In present study a statistically significant association were observed in risk factors like adult cattle (OR=2.42, P=0.015), large herd size (OR=2.52, P=0.015), animals with respiratory problems (OR=1.84, P=0.027), cattle with poor body condition (OR=3.1, P=0.005) at an individual animal-level and midland agro ecology (OR=2.45, P=0.014) at herd-level. From 19 seropositive animals’ lung tissue and nasal swabs were tested with PCR and MmmSC was detected in 17(89.5%) samples. Knowledge, attitude and practice gap were observed from study farmers with only 32.6% of respondents aware about the respiratory diseases. Contagious bovine pleuro pneumonia is the important disease of cattle in Dawo district.
