Sero-prevalence of contagious bovine pleuropneumonia and its potential risk factors in selected sites of Western Oromia, Ethiopia

Abstract

Contagious bovine pleuropneumonia (CBPP) is a disease of cattle caused by Mycoplasma mycoides subsp. Mycoides small colonies and it is one of the most important threats to cattle health and production in Ethiopia, such as at livestock farm of Bako Agricultural Research Center (BARC) an outbreak of contagious bovine pleuropneumonia occurred in May, 2011 and many animals were affected and died before the disease was identified. Therefore, this study was designed to determine the seroprevalence of contagious bovine pleuropneumonia in the selected districts of Western Oromia Zones as well as to assess the risk factors associated with the occurrence of the disease. Therefore, a cross-sectional study design was conducted from November 2013 to March 2014 in three selected districts from three Western Oromia Zones. A total of 386 sera were examined for the presence of specific antibodies of the disease by using competitive enzyme linked immunosorbent assay (cELISA). In this study, districts, peasant associations, age, sex, breed and body conditions were considered as risk factors. Thus, the overall seroprevalence of contagious bovine pleuropneumonia in this study was 28.5%. The seroprevalence of contagious bovine pleuropneumonia at districts level were 40.3%, 19.0 % and 5.7 % in Gobbu-Sayyo, Bako-Tibbe and Horro district, respectively. There was a statistically significant variation (p < 0.05) in prevalence of the disease among the districts. However, age, sex, breed and body condition were not significant (p > 0.05) with the serostatus of the animal. In conclusion, the present study indicated that the overall prevalence of CBPP in Western Oromia Zones was high, This warrants the need of the institute to follow appropriate preventive and control measures to stop further spread of the disease and appropriate controlling and prevention should be designed in general as a country level and further study should be done in the future to know the temporal pattern of the disease.
