Perspective Study on Tuberculosis in Pigs - Postmortem Findings

The prevalence of tuberculosis among pigs caused by Mycobacterium spp is described in this paper. The period between May 2008 to February 2010, a total of 108 pigs/piglets were subjected to postmortem examination showed gross pathological lesions indicative of tuberculosis in nine pigs. Amongst this, 3(2.8%) pigs belonging to three way crosses and 6(5.6%) were 75% crossbred pigs were found positive for Acid Fast Staining (AFS) technique based on the retention of primary stain by the bacilli. The infected pigs with primary tuberculous lesions in the parenchymatous organs were demonstrated with typical reproducible AF bacilli. The sources of infection might have been either concentrate feed to the pigs or cow's milk that was provided as supplement.
