Systemic (intravenous or intraperitoneal) treatment with P. acnes failed to significantly alter the growth of M. leprae in the mouse footpad. In contrast, injections of P. acnes directly into the infected footpad markedly inhibited the growth of the leprosy bacilli regardless of whether the local treatments were administered before infection or 3 months after infection with M. leprae. The effects of local treatment with P. acnes appeared to be bactericidal and not merely bacteriostatic. Clearance of the organism from the tissues was not enhanced by P. acnes treatment.</p>  a0019-9567
