Abstract
Some aspects of the pathogeny of tuberculosis was experimentally investigated by inoculating either an attenuated mycobacteria strain - BCG or a virulent strain - M.tuberculosis H37Rv into the foot pad or the cheek pouch of hamster. The inoculation of these agents determined different
patterns of lesion. The BCG-induced lesions in the foot pad had a tendency to decrease in size. On the other hand, the lesions by H37Rv showed a progressive evolution. The same pattern of evolution was observed with the lesions induced in the cheek pouch. However, the H37Rv disseminated to internal organs and the BCG did not.
