Figure 5:

Fluorescence microscopy images of (A) C. albicans cells and (B) C. albicans dead cells in biofilm treated with blue laser alone; (C) C. albicans cells and (D) C. albicans dead cells in biofilm treated with Curcumin, blue laser and KP; scale bar of 250 am, magnification 10×. Panel A and C, staining with calcofluor white; panel B and D, staining with propidium iodide. The absence of candidacidal effect for blue laser alone is visible in panel B as absence of propidium iodide (red) cells.
