A–E: Levels of chemokines elicited by challenge of oral epithelial cells with biofilms or planktonic forms of various oral bacteria. Each bar denotes mean level of triplicate determinations for each condition and the vertical brackets signify 1 SD. The asterisk (*) denotes significantly different than controls (Con for planktonic; Lens for biofilms) at least at p < 0.05. The # signifies significantly greater that other stimuli for the particular microorganism at p < 0.05.
