O-diphenoloxidase isolated from skin and serum samples of patients with lepromatous leprosy had the specificity of a bacterially derived enzyme and not that of a mammalian-derived enzyme. Only the patients who had lepromatous leprosy for over two years showed enzyme activity in serum, though all showed it in skin tissue. O-diphenoloxidase activity in serum may be a useful diagnostic marker of lepromatous leprosy.</p>  a0007-1447
