[Pathomorphologic changes in the internal organs of intact and Mycobacterium leprae-infected 9-banded armadillos]

The internal organs of nine-banded armadillos were examined histologically before and after inoculation of the animals with M. leprae. 3--4 months after the inoculation two animals developed tuberculoid structures in the lungs, liver and skin. A conclusion is made that experimental leprosy infection in nine-banded armadillos may run its course not only in the lepromatous but also in the tuberculoid form of the disease.
