Orally Administered Combined Regimens for Treatment of Mycobacterium ulcerans Infection in Mice

Eight weeks of treatment with rifampin-streptomycin sterilizes Mycobacterium ulcerans infection in mice. Because the bactericidal activity against M. ulcerans of the combination rifampin-moxifloxacin, rifampin-clarithromycin, or moxifloxacin-clarithromycin was similar to that of rifampin-streptomycin, these combinations might be considered as alternative, orally administered combined regimens for treatment of Buruli ulcer in humans.
