Presence of "difficult to isolate" mycobacteria in armadillos.

ABSTRACT

Contrary to the findings with armadillos from Louisiana and Texas, armadillos from Florida are free of natural leprosy-like infection. Examination of ear clip, nasal, blood buffy coat, liver and spleen of inoculated armadillos from Florida did not reveal the presence of any acid fast bacteria. However, using massive inocula, 6 out of 77 armadillo tissues were found to contain very negligible proportions of cultivable mycobacteria. The significance of these isolates in relation to M. leprae and also to leprosy research is discussed.
