Fig. 6: Difference of accumulation and efflux kinetics of ethidium bromide in quinolone-resistant vs. susceptible bacteria.

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 1āh. Solid lines represent mean and shaded regions represents error bars (SD). * denotes a significant difference of pā<ā0.05, ns denotes not significant; Wilcoxon matched-pairs signed-rank test. Data represents mean and SD from three independent experiments.
