Type: article
Abstract: The aim of this study was to investigate bovine tuberculosis in camels which was conducted in Eastern part of Ethiopia using post mortem examination, Mycobaterium isolation, tuberculin skin test and questionnaire based interview. Tuberculosis (TB) is an important disease for pastoralist, particularly due to prevailing habit of consuming raw milk and sharing house during night time with their animals. This study has showed prevalence rate of 8.3% (33/398) based on the post mortem examination and 6.0% (29/480) at cut off >4 mm based on the tuberculin test. From 33 camels with suspected tuberculosis compatible lesions, 12% (4/33) showed mycobacterial growth on Lowenstein-Jensen (LJ) media supplemented with pyruvate and 18% (6/33) on LJ media supplemented with glycerol. 94.7% (36/38) of the interviewed pastoralists knew about TB while only 50% (19/38) were aware about its zoonotic importance. However, only 18.4% (7/38) of the interviewed camel owners usually boil camel milk before consumption. The result of this study highlights the potential public health risk posed by TB from camels. Hence, prompt measures are required to control the possible zoonotic transmission of the disease-prioritizing on educating the pastoralist to consume camel milk after boiling. Key words: Dromedary camel, tuberculosis-compatible lesions, tuberculin test, zoonotic importance.
