Bovine Tuberculosis (BTB) is one of the main diseases caused by Mycobacterium bovis, a member of the Mycobacterium tuberculosis complex. M. bovis can infect wide range of domestic and wild animals including human. In Ethiopia, the endemic nature of bovine tuberculosis in domestic animals has long been reported and recent studies also showed that BTB is endemic mainly in cattle, in large parts of the country with considerable magnitude. The disease found to be less prevalent in rural area with characteristics of small holder farms rearing mainly Zebu cattle. However, on urban and semi-urban areas, market oriented production system leads to farming of high grade dairy cattle over a longer period of time exhibiting high prevalence level of the disease.
