  • Leprosy is caused by acid-fast bacilli of the M. leprae complex, which includes M. leprae and M. lepromatosis.
  • Transmission in the U.S. is rare, but has been documented in hunters who handle wild ninebanded armadillo.
  • The origins of M. leprae infection among armadillos, the geographic range of the infected animals, and the potential risks infected armadillos present to people have been topics of concern.
  • The infection originated amongst armadillos decades before they were ever used in leprosy research, and numerous surveys have confirmed that armadillos in the southern United States are a large natural reservoir for M. leprae; its prevalence exceeds 20% in some locales.
