a Accumulation kinetics, b efflux kinetics, c fold change in accumulation, and d fold change in efflux of ethidium bromide in E. coli MG1655 and E. coli RPTU54. e Accumulation kinetics, f efflux kinetics, g fold change in accumulation, and h fold change in efflux of ethidium bromide in A. baumannii SDF and A. baumannii AYE. Fold change was calculated from fluorescence reading obtained at the end of 1 h. Solid lines represent mean and shaded regions represents error bars (SD). * denotes a significant difference of p < 0.05, ns denotes not significant; Wilcoxon matched-pairs signed-rank test. Data represents mean and SD from three independent experiments.
