Persister cells in exponential growth phase in presence of combined antibiotic treatment. The exponentially growing cells (USA300 LAC, msaABCR mutant and the complementation) were treated with combined antibiotics. a. daptomycin/rifampicin (40× MIC), b. vancomycin/rifampicin (20× MIC), c. linezolid/rifampicin (20× MIC), d. daptomycin/gentamicin (20× MIC), e. vancomycin/gentamicin (20× MIC), and f. linezolid/gentamicin (20× MIC). Student’s t-test (OriginPro) was used to compare the results of the wild-type to mutants at respective designated time points (* p-value <0.05, ** p-value <0.005). These results represent the means of three independent experiments. Error bars represent SE
