FIG. 4.

(a) Epi-fluorescence contrast-enhanced image of Fig. 3f, showing areas used to evaluate pixel intensities for kinetic data curves presented in Fig. 5. Scale bar, 25 μm. (b) DIC image of corresponding area of C. albicans biofilm, taken 12 min before exposure to CHG, with positions of cellular structures demarcated in the epi-fluorescence image indicated. Black arrows indicate yeast cells, and white arrows indicate filamentous forms. The cell labeled “r” corresponds to the cell indicated by the arrow in Fig. 2.
