Figure 1. Cellular adhesion and dextran-binding activities of TW strains and MT8148 (mean ± SD; n = 5). (A) Sucrose-independent cellular adhesion to saliva-coated hydroxyapatite of MT8148, GbpC-defective mutant (C1), and TW strains. (B) Dextran-binding activity of MT8148, C1, and TW strains. There were statistically significant differences between MT8148 and the other strains by Fisher's PLSD analysis. (**P < 0.01, ***P < 0.001).
