| Abstract: | The hydrophobicity and adhesion to saliva-coated hydroxyapatite of Streptococcus salivarius HB and the mutants HB7, HBV5 and HBV51 were measured. The mutants HB7 and HBV51 showed a significant reduction in adhesion to salivacoated hydroxyapatite and hydrophobicity compared with the mutant HBV5 and the parent strain. This supports the view that hydrophobic interactions are important for bacterial attachment in the oral cavity and is in contrast to previous studies on the hydrophobicity of these strains. |
