Membrane permeability by using fluorescence dye (Hoechst 33342) accumulation in the absence and presence of the efflux pump inhibitors (EIs) PAβN and CCCP. (a) Fluorescence values of each isolate were detected in the absence of EIs. (b) and (c) Fold changes in each isolate were calculated from the fluorescence values in the presence of individual EIs divided into those in the absence of EIs. The asterisk (*) indicates a significant difference compared to the reference BCRC 10692 (p ≤ 0.05).
