The aim of the present study was to determine the source and transmission route of Streptococcus mutans. The frequency of this organism in saliva and plaque samples was compared among fifteen pairs of mothers and their children. The results showed that most of the mothers harboured almost equal or greater levels of S. mutans than their children. Similarities of the distribution of various serotypes and mutacin types were observed between these mothers and their offspring. Samples were also collected from plaque and/or carious lesions of the relatives of the subjects who carried one of the serotypes other than serotype c as the dominant S. mutans. The strains of the same serotypes of S. mutans which possessed similar mutacin patterns were predominantly detected in the siblings and mothers of each subject. However, a similar distribution of S. mutans strains was not clearly observed in other relatives including fathers, aunts, uncles and grandparents.
本研究的目的是确定变形链球菌的来源和传播途径。在15对母婴中比较了这种微生物在唾液和菌斑样本中的出现频率。结果显示，大多数母亲口腔中变形链球菌的含量与她们的孩子相当或更高。观察到这些母亲及其后代之间各种血清型和变链菌素类型的分布具有相似性。还从携带除c血清型以外的其他血清型作为优势变形链球菌的受试者亲属的菌斑和/或龋损中采集了样本。在每个受试者的兄弟姐妹和母亲中主要检测到具有相似变链菌素模式的相同血清型的变形链球菌菌株。然而，在包括父亲、姑姑、叔叔和祖父母在内的其他亲属中，未明显观察到变形链球菌菌株的相似分布。
