FIGURE 3

Biofilm structures and biomass of S. aureus strain Newman cultured in trypsin soybean broth (TSB) with 50 μg/ml advanced glycation end product (AGE)-bovine serum albumin (BSA) and other control, measured by confocal laser scanning microscopy (CLSM). (A) Live/Dead staining images. The viable bacteria were stained by SYTO9 (green) and PI stained the dead bacteria (red). The images were showed after merging (green, red, and yellow). (B) Comparison of biofilm thickness (*P < 0.05 compared with TSB group; #P < 0.05 compared with TSB + BSA group).
