Antibody, caries preventive agent containing the same as an active ingredient, and methods for producing the same

摘要

Cell-associated glucosyltransferase 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 said enzyme was prepared from eggs of the hens immunized with said 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.
