title: Changes in hydrolytic enzyme activities in armadillos infected with Mycobacterium leprae.
abstract: The activities of hydrolytic enzymes in various organs of armadillos infected with Mycobacterium leprae were compared with those in normal armadillos. Except for aspartate aminopeptidase and esterase, the levels of the other enzymes in liver, spleen and inguinal lymph nodes were significantly higher in armadillos infected with M. leprae compared with those in non-infected ones. These enzymes levels were at a maximum when the animals were sacrificed 22 to 30 months post-inoculation, a period when the bacterial load in the animals had also reached a maximum. Animals infected with M. leprae but not showing any signs of disseminated infection behaved similar to those in the non-infected group. The observed changes in enzymatic activities were not due to bacterial enzymes and so can be related to tissue damage caused by M. leprae.
