The present study was undertaken to assess the prevalence of bovine tuberculosis among buffaloes in Belgaum, Dharwad and Bagalkote districts of North Karnataka, for a period of eight years (2002 to 2009). A total of 2184 buffaloes belonging to 30 organized farms were screened by single intradermal tuberculin test using bovine tuberculin Purified protein derivative. Overall prevalence of tuberculosis among buffaloes was found to be 0.96 per cent. Prevalence was higher in females (0.97%) than males (0.84%) and in Murrah (1.02 %) than Surthi (0.85 %). Analysis of the temporal pattern revealed a gradual declining trend over a period of eight years.
