Abstract: The study was carried out to investigate bovine tuberculosis by necropsy inspection in different abattoirs of Meghalaya. Gross visual lesions were found in 26 carcasses. Suspected 39 tissue samples were collected from 26 carcasses. Pre-culture stain revealed 30 (76.92%) and culture growths were from 31 (79.49%) tissue samples. Highest lesions were recorded in lymph nodes (48.71%) followed by lungs (28.20%) and liver (23.07%). Pre-scapular (47.37%) and retropharyngeal (31.58%) contribute more lesions than other lymph nodes. Visual inspection may serve as good screening method for tuberculosis infected carcasses although pre culture staining and culture of bacteria from suspected lesion samples is necessary to have a concluding remark about the infection. The study also confirms the endemic status of bovine tuberculosis in these areas.
