A case of 6-year-old died cow of military dairy farm was submitted to the Division of Pathology, IVRI for necropsy examination. Grossly, variable sized tubercles were present on vital organs as well as the classical histopathological lesions strongly suggested the case of bovine tuberculosis.  Furthermore, the bacterial isolation, various biochemical tests and a 12.7 kb fragment based multiplex PCR confirmed the involvement of Mycobacterium tuberculosis in cow.
