Oxyclozanide does not induce biofilm dispersal. Twenty-four hour biofilms were treated with oxyclozanide, tobramycin or the combination, in equal molar two-fold dilutions, for 6 h. The effect on biofilm biomass was quantified by staining with crystal violet. The experiment was performed twice in triplicate. The results represent the means plus SEM. A one-way ANOVA followed by Bonferroni’s multiple comparison post hoc test was used to determine statistical significance between tobramycin alone and the untreated control (*P < 0.05) and between the combination and tobramycin alone. NS, not significant.
