Biofilm formation by P. gingivalis wild-type and mutant strains. Biofilm formation was examined after 34 (A) and 48 (B) hours of culturing in BHI-HM broth. OD492/620 absorbance was measured to determine the biofilm mass. Data shown are representative of three independent assays. The results are expressed as the mean ± SD of a triplicate assay. Similar results were obtained in three independent experiments.
