Mean cell counts from three replicates, with standard deviations (SD) in parentheses.

ATP-based luminescence quantification was assessed in at least three independent experiments and was expressed as the mean value (SD) percent relative light units (RLU) vs. saline-treated biofilms (control).

The data were analyzed by use of 1-way ANOVA, followed by the Dunnett T3 as a post hoc test. All statistical analyses were performed using IBM SPSS version 22 statistical software (IBM SPSS, Chicago, IL, USA).

p < 0.01 vs. control.

p < 0.05 vs. CH-treated biofilms.

p < 0.05 vs. CHX-treated biofilms.
