Abstract
Total and insoluble dextransucrase activities of 10 strains of oral streptococci were measured by a modified filter disk assay. Strains that were nonadherent to hard surfaces had only low levels of insoluble dextransucrase activity. A physical rather than metabolic mechanism is suggested to explain the decreased insoluble and increased soluble activities observed when dextran T-10 is added to the media.Keywords
