Abstract

In this study, homogenized mixture of tubercle and pulmonary lymph node showed up tuberculin(PPD) positive dairy cattle was inoculated in experimental animal, and was cultured on medium(Lowenstein Jensen medium, 3% Ogawa). The results obtained through the survey were sumerized as follows ; 1. In experimental animal, goat and rabbits were decreased body weight(25∼28%) and died in 90 days with severe pathogenicity. Rats are slight pathogenicity. 2. Goat, rabbits and rats showed up severe lesions In lung, rabbits was also lesions other organs (kidney, appendix, ileocecum, and I lymph node). 3. Mycobacterium was grown between 5 weeks and 8 weeks on Lowenstein Jensen medium and 3% Ogawa medium. 4. Biochemical test of Mycobacterium cultured on medium was that niacin, nitrate reduction, tween 80 hydrolysis and catalase test were negative, but that urease test was positive. Therefore it was Mycobacterium bovis (M. bovis).
