Four hundred and sixty-two children, aged 10-14 years, from eight areas were examined for Streptococcus mutans in saliva and for dental caries. Strep. mutans strains from some samples were further characterized by serological and biochemical methods. Strep. mutans was identified in 98 per cent of the children and 40 per cent showed high counts. Serotypes c and d dominated among the strains. The distribution of Strep. mutans among the children varied between the eight areas but was not correlated with the difference in caries prevalence which ranged from 38 to 88 per cent. In individual children, however, there was an association between high counts of Strep. mutans and the presence of dental caries. Thus, Strep. mutans can be widely distributed and occurs in high numbers in a population with a low prevalence of caries.
对来自八个地区的462名10至14岁儿童的唾液进行了变形链球菌检测，并检查了龋齿情况。部分样本中的变形链球菌菌株通过血清学和生化方法作了进一步鉴定。98%的儿童检测出变形链球菌，40%的儿童该菌数量较高。菌株中以c型和d型血清型为主。八个地区儿童中变形链球菌的分布情况有所不同，但与龋齿患病率38%至88%的差异并无关联。然而，在个体儿童中，变形链球菌数量多与患龋齿之间存在关联。因此，变形链球菌可广泛分布，在龋齿患病率较低的人群中也大量存在。
