Complemetation of the antibiotic-resistant phenotype of the yddB or lamB mutant. (A) The MICs of novobiocin were examined in 0.01% arabinose-containing agar plates with the agar dilution method according to the Clinical Laboratory Standards Institute guidelines in the wild-type or yddB mutant with or without a pBAD-YbbB plasmid. After incubation at 37°C for 20 h, photographs of the plates were taken with a digital camera. (B) The MICs of vancomycin were examined in 0.01% arabinose-containing agar plates with the agar dilution method in the wild-type or lamB mutant with or without a pBAD-LamB plasmid.
