A total of 8 tissue samples from the goat showing positive tuberculin tests were investigated from 1986 to 1987. Five strains of Corynebacterium pseudotuberculosis (C. pseudotuberculosis) and 2 strains of Mycobacterium bovis have been isolated in this study. 
A total of 265 serum samoles collected from goat during 1987 and 105 sampl!c' sera collected from cattle exhibiting positive tubercu -Jin tests during 1982 were detected by agar gel precipitation test using an antigen prepared from C. pseudotuberculosis exotoxin. The results indicated that 30 goat serum samples and 10 serum samples from these cattle revealed the positive reactions that sugges-ted they were previously infected by C. pseudotuberculosis. 
The patterns of drug susceptibility were found to be similar for all 5 local isolates of C. pseudotuberculosis on the basis of Kirby-Bauer's standard procedures. They were susceptible to ampicillin ( 10 Pg), bacitracin ( 10 µg), chloramphenicol (30 µg), doxycycline (30 µg), erythromycin (15µg), lincomycin (2µg), tetracycline (5 µg) and sulfame-thoxazol-trimethoprim (23.75µg, 1.25µg), respectively.
