Fig. 5From: Autoinducer-2 regulates Pseudomonas aeruginosa PAO1 biofilm formation and virulence production in a dose-dependent mannerEnumeration of viable bacteria under different concentrations of AI-2. Data represent the means and standard deviations of three independent experiments. Triangles denote a statistically significant difference from the control (P < 0.05). Squares denote a statistically significant difference from the 10nM AI-2 group (P < 0.05)Back to article page
