Abstract
Cell-associated glycosyltranferase of S. mutans serotypes c, e or f producing dental caries was isolated and purified and its characteristics as an enzyme were revealed. Furthermore, an antibody against the enzyme was prepared from eggs of the hens immunized with the enzyme. Since this antibody effectively prevents adherence of the aforementioned S. mutans to tooth surfaces, it is useful as an effective component for a dental caries prophylactic composition.
