Fig. 1 Growth rates of strains 1 to 5 of M. tuberculosis, expressed as growth indices as a function of time, when tested with four rifaximin concentrations (A, 6 ng/mL; B, 20 ng/mL; C, 90 ng/mL; D, 270 ng/mL), compared with growth indexes of controls (C1 to C5) in the absence of antibiotic. Treated cultures, solid lines; control, dotted lines.
