Abstract

During the 2^nd week post inoculation of thirteen rabbits with Mycobacterium bovis tuberculosis lesions appeared in the lungs, liver, spleen, kidney, mediastinal and hepatic lymph nodes and in the omentum with an equal distribution in these organs. During the 4^th week post inoculation, these tuberculosis lesions increased in size to become well developed granulomas with caseated centers. These granulomas persisted to the 6^th, 8^th and 10^th weeks post inoculation and became more encapsulated later on. Three rabbits died during the 7^th week post inoculation due to generalized tuberculosis.
