Bovine tuberculosis is of great zonootic importance. The present project was designed to study the prevalence of bovine tuberculosis (TB) in cattle and buffaloes. Suspected population of live animals were screened out by intradermal tuberculin (IDT) test. Lungs suspected of tuberculosis were collected from the Lahore Slaughter House, for isolating the TB organism. Dogs brought to the Dog Hospital, CVS, Lahore were also checked for the presence of TB. A total of 344 cattle and buffaloes were tested by IDT test. Twenty five (7%) animals were observed as positive to IDT test and seven (2%) animals were tested as doubtful. Milk and faecal samples were collected from the positive animals however, none of the samples was positive for mycobacterium by microscopic or cultural examinations. On microscopic examination of 20 lung samples, only four (20%) lungs indicated the presences of acid-fast bacilli. While on culture examination, 14 strains were detected. All the 14 s trains were inoculated into rabbits intravenously to study the pathogenicity. Thirteen isolates were found to be pathogenic for rabbits. On postmortem examination there were typical tubercles on the lungs of rabbits. Twenty five dogs were tested by IDT test. Two dogs i.e. 8% were found to be positive for tuberculosis. From the study, it was concluded that tuberculosis is quite common in animals. Strong measures should be taken by government and private authorities to eradicate disease from animals.
