Effect of Res on intracellular CPX-accumulation in SPN strains. Fluorometric measurement of intracellular accumulation of CPX in the indicated strains after 5 min incubation with the specified CPX concentrations either in the presence (dark gray bars) or in the absence (white bars) of 20 µg/mL Res. At least three independent replicates were conducted and mean values with and without Res of each strain were statistically compared using Student’s t-test (* p < 0.05; *** p < 0.005; **** p < 0.001).
