Curator's Comment: Growth of the organisms was determined after reincubation at 37°C for 16 to 24 h by visual determination of a color change from blue to pink. The MIC was defined as the lowest concentration which prevented the color change.
The MICs of cloxyquin for 150 clinical isolates of Mycobacterium tuberculosis ranged from 0.062 to 0.25 g/ml. The MIC50 and MIC90 were 0.125 and 0.25 g/ml, respectively.
