The 9 banded armadillo and humans have in common that they can both get infected with leprosy, a chronic infectious disease caused by the bacteria Mycobacterium leprae. The armadillo is considered a natural reservoir for the bacteria and can transmit it to humans through contact with its body fluids or tissue. While transmission from armadillos to humans is rare, it is more common in certain parts of the world, including the southern United States, where armadillos are more prevalent.
 The association between 9-banded armadillos and leprosy adds a unique layer to the understanding of zoonotic diseases, which are infections that can be transmitted between animals and humans. Mycobacterium leprae, the bacteria responsible for leprosy, can find a host in armadillos, contributing to the ongoing conversation about the complex dynamics of infectious diseases. While leprosy transmission from armadillos to humans is not widespread, the prevalence in certain regions underscores the importance of studying such interactions to develop effective preventive measures. This intersection of wildlife and human health highlights the intricate web of connections in the natural world.
