摘要
本文报道了用直接免疫荧光法和琼脂双向扩散试验,对103株由57名5~6岁患龋儿童的无龋裂沟表面的混合牙菌斑中所分离的变形链球菌菌株进行血清学分型。结果d型为57株,占55.34%;c型22株,占21.36%;g型21株,占20.39%:e型3例,占2.91%。
The serotypes of 103 strains of streptococcus mutans,isolated from the dental plaques of 57 preschool children with caries,were determined by direct immunofluorescent method and agar double immunodiffusion test.The 7 reference strains of the serotypes AHT(a),FA-1(b),Ingbritt(c),OMZ 176(d),LM-7(e),OMZ 175(f)and Kl(g)suggested by Bratthall and Perch were used.Antibodies used for identification were prepared by immunizing rabbits with each of the above organisms.Of the 103 strains isolated,57(55.3%)were of serotype d,22(21.4%)serotype c,21(20.4%)serotypegand 3(2.2%)serotype e.No serotypes a,b or f were isolated.
