RESUMO

The mutant prevention concentration (MPC) of a C-8-methoxy fluoroquinolone exhibited a narrow distribution for 14 genetically diverse clinical isolates of Mycobacterium tuberculosis, indicating that results from single-isolate studies are likely to be representative. When one isolate was challenged with a variety of antituberculosis agents, C-8-methoxy fluoroquinolones were exceptional in having MPCs below the maximum concentration attained in serum by use of commonly recommended doses.
