DL suppresses the formation and development of C. albicans biofilm. A: C. albicans biofilms formed in the presence of DL were subjected to XTT reduction assay. B: 24-hour old biofilms were treated with different concentrations of DL for another 24 h, followed by XTT assay. **, p < 0.01. C: C. albicans biofilms formed in the absence or presence of DL (16, 32 and 64 µg/mL) were stained with CFW and washed with PBS, then subjected to CLSM for the xyz-mode recording. The three-dimensional pictures shown were built using Imaris 7.2.3 (BitPlane, Switzerland)
