Susceptibility of Mycobacterium avium and Mycobacterium intracellulare to various antibacterial drugs.
Mycobacterium avium and M. intracellulare of human and natural sources, identified by the Gen-Probe Rapid Diagnostic System for M. avium Complex (MAC) were studied for susceptibility to eight different drugs. In the case of human isolates of MAC, the following was noted. M. avium showed nearly the same susceptibility to streptomycin, kanamycin, ethambutol, and clofazimine as was seen with M. intracellulare. M. avium was much more resistant to rifampicin and rifabutin than was M. intracellulare, and M. avium was more susceptible to quinolones such as ofloxacin and ciprofloxacin. Conversely, in the case of MAC from natural sources, there was no difference between the susceptibility of M. avium and M. intracellulare to these antibacterial agents.
