To evaluate the use of swine as a model of human and bovine tuberculosis, eighteen 4-week-old pigs were exposed to Mycobacterium bovis. Groups of 3 pigs were exposed to either 10*4 or 10*8 cells of a recent bovine isolate of M. bovis by IV, intratracheal, or tonsilar routes of inoculation. Pigs were observed for development of clinical signs and were euthanized at 1 or r2 months after challenge or earlier, if severe clinical signs developed. Gross lesions were recorded at necropsy and tissues were collected for histopathology and culture. The nature and extent of lesions produced were compared between different routes of inoculation and doses of M. bovis. These results will be useful for characterization of a swine model of tuberculosis in humans and cattle.
