Abstract
Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle caused by Mycoplasma mycoides subsp.mycoides small colony (Mmm SC). A cross-sectional study design was conducted in selected district of East Wollega and West Showa zones of western Ethiopia from December 2016 to April 2017 to assess the knowledge, attitude and practice (KAP) of farmers towards CBPP disease, to estimate seroprevalence and associated risk factors of CBPP, and to detect the causative agent of the disease from seropositive animals. A total of 113 households were purposively selected and interviewed with structured questionnaire. Consecutively, from interviewed households a total of 576 animals were randomly selected and serum samples were collected. The serum samples tested with c-ELISA and for further confirmation from 4 seropositive animals lung tissue were sampled and detection of Mmm SC was made using PCR. The overall animal and herd level seroprevalence of CBPP were 14.6% (95%CI: 11.80-17.73) and 54% (95%CI: 44.35-63.40), respectively. Among the potential risk factors considered, multivariate logistic regression analysis showed district, age, herd size, and history of respiratory disorder were statistically significant(p<0.05). Cattle that found in Ilu Galan district were two times (OR=2.4, P=0.002) more likely to be affected by CBPP than Sibu Sire, adult cattle were two times (OR=2.1, p=0.009) more likely to have CBPP than young, large herd cattle were six times (OR=6.1, P= 0.000) more likely to be affected by CBPP than small herd, and animals that had history of respiratory problems were two times (OR=1.9, P=0.021) more likely to be seropositive than those hadn‟t. Of 4 seropositive animals lung tissue tested with PCR, Mmm SC was detected in all samples (100%), and the presence of the disease was confirmed in the area. However, the KAP questionnaire result indicated there were knowledge and attitude gap among the study farmers related to the disease in general. Besides, majority of farmers were practicing poor animal husbandry that created favorable conditions for the distribution of the disease in the community. Therefore, to deal with CBPP disease further study with large coverage using reliable tools like molecular technique is an essential, plus cattle herders should be made aware of about the disease and its importance through veterinary extension education.
