Figure 2

In vitro evaluation of antimicrobial activity of ozone (A) and chlorhexidine (B) against C. albicans by flow cytometry. Distribution of fluorescence intensity from yeast cells treated with ozone (A) for 30, 60, 120, and 180 seconds ((b), (c), (d), and (e), resp.), stained with DiBAC4 (A1), FUN-1 (A2), and PI (A3); and cells treated with 0.2 (f) and 2% (g) of chlorhexidine (B) for 3 minutes, stained with DiBAC4 (B1), FUN-1 (B2) and PI (B3). Fluorescence of untreated cells stained with fluorescence marker is represented by (a).
