Three different types of lepromin response were described, namely the lepromatous, the borderline, and the tuberculoid lepromin reactions. It was found that 10 out of the 11 animals with a lepromatous lepromin reaction and the one animal with a borderline lepromin reaction developed disseminated disease. The two with a tuberculoid lepromin reaction and one of the 11 with a lepromatous lepromin reaction failed to develop leprosy. It is suggested that by using the lepromin response it is possible to assess, to a great extent, the susceptibility of armadillos to infection by M. laprae. The pros and cons of using the armadillo as an animal model for a vaccine trial are briefly discussed.</p>
