FIG 1.
Kinetics of biofilm dispersal by TEC against MRSA S. aureus ATCC 33591 biofilms. (A) Log10 CFU counts per coupon. (B) Total biomass assay (expressed as the percentage of time zero control). (C) Pictures of biofilm samples exposed to TEC for the indicated times (C-, negative control [coupon incubated in sterile culture medium]) stained with crystal violet. The values indicate the means of triplicate experiments (± standard error). Statistical analysis, repeated measure ANOVA, followed by paired t tests with Holm correction. *, P < 0.05.
