Efficacy of antibiotic treatments against biofilm cells. The cells on mature biofilms (48 h incubation) were treated with 512 μg/mL vancomycin, 128 μg/mL daptomycin, 1024 linezolid, and 256 μg/mL tigecycline. After 24 h of the antibiotic treatments, the cells were stained with Live/Dead kit. 1 indicates the histograms of frequency and intensity of live and dead cells. 2 indicates the acquired 2D view images obtained at 1.4 objective and magnification of ×100; (a) linezolid, (b) vancomycin, (c) tigecycline, (d) daptomycin.
