    摘要: A method for preparing a vaccine for dental caries comprises the step of culturing a variant which is obtained by integrating a protein antigen (PAc)-expressing gene into the chromosomal gene of a Streptococcus mutans GS-5 strain to obtain the protein antigen, the protein antigen being produced on the surface of cells of oral Streptococcus mutans or it being extracellularly produced by the microorganism and having a molecular weight ranging from about 170,000 to 220,000. Streptococcus mutans GS-5 (K-3), in which a protein antigen-expressing gene is integrated into the chromosomal gene thereof, has an ability of producing the protein antigen on the surface of the cells or extracellularly. A preventive vaccine composition for dental caries for nasal drops comprises the protein antigen thus produced by the strain: Streptcoccus mutans, the vaccine being intranasally administered. The method makes it possible to enhance the yield of PAc and to simplify processes for purifying PAc. The vaccine composition makes it possible to internally easily absorb the protein antigen, PAc, in high efficiency and it also makes it possible to effectively increase the antibody titer observed after the administration thereof. 1
