FIG. 2.
Survival of C. albicans biofilms challenged with amphotericin B and chlorhexidine. Biofilms were treated with 100 μg/ml amphotericin B, 100 μg/ml chlorhexidine, or a combination of the two antifungals for 24 h. The biofilms were washed and sampled for CFU determination before and after antibiotic treatment. The experiment was performed in triplicate, and the error bars indicate standard deviations.
