Abstract

Numerous S. mutans strains isolated from human dental plaque and from that of rats and hamsters were classified by a well-known biochemical differentiation system for the separation of the serotypes "a to e", and by seven different biotypes (I-VII). 182 S. mutans strains from human plaque were assigned to the following serotypes: "c" = 68%, "d" = 19%, and "b" and "e" = 4% each. Serotype "a" was not found at all and 10 strains could not be classified. Out of 60 S. mutans strains from the oral cavity of rats, 85% belonged to serotype "c", while in 25 strains from hamsters serotypes "e" and "d" predominated.

摘要

从人类牙菌斑以及大鼠和仓鼠牙菌斑中分离出的众多变形链球菌菌株，通过一种著名的生化鉴别系统进行分类，以区分“a至e”血清型，并分为七种不同的生物型（I - VII）。来自人类牙菌斑的182株变形链球菌菌株被归为以下血清型：“c” = 68%，“d” = 19%，“b”和“e”各占4%。完全未发现血清型“a”，且有10株无法分类。在从大鼠口腔分离出的60株变形链球菌菌株中，85%属于血清型“c”，而在从仓鼠分离出的25株中，血清型“e”和“d”占主导。
