Persister cells from stationary phase growth using combined antibiotics. The cells from stationary growth phase (USA300 LAC, msaABCR mutant and the complementation) were treated with combinations of antibiotics. a. daptomycin/rifampicin (320× MIC), b. vancomycin/rifampicin (40× MIC), c. linezolid/rifampicin (160× MIC), d. daptomycin/gentamicin (30× MIC), e. vancomycin/gentamicin (20× MIC), and f. linezolid/gentamicin (20× MIC). These results represent the means of three independent experiments. Error bars represent SE. 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)
