New disease strain shows up in patients and animals in Deep South
People infected with leprosy in the United States often have the same previously unknown strain of the microbe Mycobacterium leprae that is also carried by armadillos. Though it’s been known for decades that armadillos can harbor leprosy, also called Hansen’s disease, the discovery of the overlapping strain strengthens the long-held assumption that armadillos can infect people directly.
