Evaluation of Alternative Methods to Assess the Biological Properties of Propolis on Metabolic Activity and Biofilm Formation in Streptococcus mutans

Figure 5

Effect of different concentrations of polyphenol-rich extract of propolis (EP) on biofilm metabolic activity, determined by flow cytometry in S. mutans. The percentage of biofilm living cells was expressed as median ± SD. from the nonparametric Wilcoxon test when compared to untreated cells (control).
