Adherence of OG1RF and its Δace, ΔebpABC, and ΔaceΔebpABC deletion mutants to the collagen-secreting cell line 3T6. Each bar represents mean percentages ± SD of bacteria adhering to cells coating 9 wells from three independent experiments. Data for each strain were normalized with respective data of OG1RF, which was set to 100%. Mean adherence percentages of different strains were compared using ANOVA and Bonferroni's post test. *, P < 0.001 versus the wild type by post hoc test; **, P < 0.001 versus the wild type and P < 0.01 versus the Δace mutant by post hoc test.
