Abstract:
Contagious bovine pleuropneumonia (CBPP) is one of the most important threats to cattle
health and production in Ethiopia. At the livestock farm of the Bako Agricultural Research
Center, an outbreak of respiratory disease of cattle occurred in May 2011, and many animals
were affected and died before the disease was diagnosed. Therefore, this study was designed
to determine the seroprevalence of CBPP antibodies in selected districts of Western Oromia
Region and to assess the potential risk factors for the occurrence of the disease. A crosssectional study was conducted from November 2013 to March 2014 in three selected districts
of Western Oromia Region. A total of 386 sera were examined for the presence of specific
antibodies against Mycoplasma mycoidesmycoides small colony (MmmSC), using a competitive
enzyme-linked immunosorbent assay. The risk factors that were evaluated in this study were
geographical location, age, sex, breed and body condition. The overall seroprevalence in this
study was 28.5%. The seroprevalence of Mycoplasma mycoidesmycoides small colony antibodies
at the district level was 40.3%, 19.0% and 5.7% in Gobbu Sayyo, BakoTibbe and Horro districts,
respectively. There was a statistically significant variation ( p < 0.05) in the prevalence of
antibodies amongst the districts. However, animal-related risk factors, such as age, sex, breed
and body condition, were not significantly associated ( p > 0.05) with the serological status of
the animal. This study showed that the overall prevalence of CBPP in Western Oromia Zones
was high. This warrants the implementation of appropriate preventive and control measures
to minimise the economic losses associated with the disease
