Researchers from the University of Tennessee conducted a study on the seroprevalence of leprosy in nine-banded armadillos in Tennessee, USA, from 2021-2022. Despite concerns about the expansion of the armadillo's range increasing human exposure to leprosy, the study found that all 61 armadillos tested were seronegative for Mycobacterium leprae, the causative agent of leprosy. This research, supported by the Alliance of Women Philanthropists and the University of Tennessee at Chattanooga, provides valuable insights into the potential impact of armadillo range expansion on public health.
