Effects of glucose on biofilm formation and resistance in the presence of HoS. (a) Effect of HoS on P. aeruginosa biofilm formation by crystal violet staining. (b) CLSM observation and coverage ratio analysis of glucose‐treated biofilms. Scale bar, 20 μm. (c) Biofilm formation of different clinical isolates in response to HoS treatment as assessed by crystal violet staining. (d) Synergistic biofilm‐promoting effect of HoS plus glucose by crystal violet staining. (e) Synergistic effect of glucose plus HoS on biofilm formation and OFLX resistance of P. aeruginosa determined by XTT staining. These experiments were independently repeated three times in triplicate
