Contagious Bovine Pleuropneumonia (CBPP), a disease contributes significantly to cattle morbidity and mortality, remains the most important infectious disease of cattle in Ethiopia. Hence, a cross-sectional study was carried out in nine districts of Sidama Zone, to estimate animal level seroprevalence of CBPP in cattle, and to assess risk factors associated with its occurrence using competitive enzyme linked immunosorbent assay (c-ELISA). In the investigation, a total of 462 serum samples were collected and tested and the overall animal level sero-prevalence was recorded as 25.3%. Among the host related potential predisposing factors assessed, age and body condition of the animals were not significantly (p>0.05) associated with the occurrence of the disease, whereas sex of cattle was found significantly (χ2=8.447, df=2, p=0.004) associated. There was statistically significant (χ2=21.2, df=8, p=0.006) difference in the occurrence of CBPP among the nine districts of the Zone at individual animal level. Multi-variable logistic regression analysis showed that, males had 2.6 times (OR=2.6; CI=1.3-5.2) the odds of being negative for CBPP than female. Except sex of an animal, the other categorical variables were not significantly associated (p>0.05) with occurrence of CBPP on univariable as well as multivariable logistic regression analysis. It is concluded that, CBPP is moderately prevalent in the study area. Therefore, it is needed to design and implement control measures directed at lowering and preventing further spread of the disease.
