| Abstract: | Specimens of lung, liver and mesenteric lymph node from cows and buffaloes slaughtered in the Lahore area were cultured to investigate the type of mycobacteria involved in bovine tuberculosis. Employing the concentration method, 56 out of 530 cattle were found to be culture positive for acid-fast bacteria, 48 being Mycobacterium bovis and eight atypical mycobacteria. No M tuberculosis or M avium was isolated. Most of the isolated M bovis strains were found to be highly virulent for rabbits. |
