Dansyl-PMB binding affinity in Lab-WT and clinical isolates. CLSM images of Lab-WT, PMBR, and PMBS strains are shown. The fluorescence of the lipophilic dye FM 4-64 (red) was observed in all of the strains, indicating that the membrane was well maintained. The fluorescence of dansyl-PMB (green) was observed in the Lab-WT and PMBS strains but not in the PMBR strains. The FM 4-64 and dansyl-PMB images were merged. Scale bars represent 10 μm.
