sciencehabit writes "For years, scientists have speculated that armadillos can pass on leprosy to humans, and that they are behind the few dozen cases of the disease that occur in the US every year. Now, they have evidence. A genetic study published in The New England Journal of Medicine shows that US armadillos and human patients share what seems to be a unique strain of the bacterium that causes leprosy. If an armadillo's blood 'got on my tires of my car from running [the animal] over, I would wash it down,' advises one expert. 'And I would not dig in soil that has a lot of armadillo excrement.'"
