| Summary |
From July 1988 to June 1989, 224 diary cows, 18 milk goats and 18 deer which all gave a positive reaction in tuberculin skin test were examined for Mycobacterium spp. infection. Ninety seven strians of M. bovis, 2 strains of M. avium complex and 3 strains of Runyon IV were isolated from 100 cows with gross lesions. Five strains of M. bovis and 4 strains of M. avium complex were isolated from 9 milk goats with gross lesions. Nine strains of M. bovis and 2 strains of M. avium complex were
isolated from 11 deer with gross lesions. The percentage of cows with gross lesions was lower than before. It was attributed to the policy of eradication. However, high occurance of tuberculosis of milk goat and deer needed to be paid more atte-tion on it.
