Vancomycin susceptibility assay. (a) Colony counts (CFU/ml) of WT, the airSR mutant, and the airSR complementary strains on MH agar plates containing vancomycin (0.6 μg/ml). The colonies were counted after incubation at 37°C for 24 hours. (b) The growth of the wild-type, the airSR mutant, and the airSR complementary strains in MH broth at 37°C. Vancomycin concentrations of 0 or 1.0 μg/ml. (**indicates P < 0.01).
