SUMMARY Three strains of Mycobacterium avium complex organisms, serotypes 6, 14 and 18 isolated from typical tuberculous lesions in cattle were examined for pathogenicity and ability to sensitise cattle to avian and bovine tuberculin. Each strain caused tuberculoid granulomas at the site of subcutaneous inoculation but no lesions elsewhere. Sensitisation to bovine tuberculin was detected in the caudal fold test in 11 of 18 inoculated animals 8 weeks after injection. In a simultaneous comparative cervical test, reactions to avian tuberculin were much larger than reactions to bovine tuberculin in all inoculated animals.
