Ionic interaction of oral streptococcal bacteria studied by partition in an aqueous polymer two-phase system.
The net surface charge of various oral streptococci were assessed by aqueous two-phase partitioning in a dextran-polyethylene glycol system. Great variability was found among individual strains within all species tested. Type 1 strains of Streptococcus sanguis serotypes which have been found to be more adherent, exposed a lower negative net surface charge than Type 2 strains.
