Biofilm formation in mono- and dual-species model. Data presented here were generated from more than ten independent sets of experiments and were further analyzed using a non-parametric Kruskal-Wallis Test and student t-test. This graph shows the average (± standard deviation, in error bars) of CFU in biofilms formed by S. mutans and the other oral bacteria tested when grown in the mono- and dual-species models with S. mutans. A *, # and @ indicates significant difference at P < 0.05, 0.01 and 0.001, respectively, when compared to those grown in mono-species biofilms. All abbreviations are the same as in Figure 1.
