Abstract
The "mutans-like" streptococci can be separated into five species (Streptococcus mutans, S. rattus, S. sobrinus, S. cricetus, and S. ferus) that belong to the same rRNA homology cluster. New valuable chemical characters for differentiation of the five species--such as peptidoglycan type, presence of cell wall teichoic acid, and cell wall sugar composition--are described. The peptidoglycan type and the cell wall sugar composition can be determined by rapid procedures.
摘要
“变形链球菌样”链球菌可分为五个种（变形链球菌、鼠链球菌、远缘链球菌、仓鼠链球菌和野鼠链球菌），它们属于同一个rRNA同源簇。本文描述了用于区分这五个种的新的重要化学特征，如肽聚糖类型、细胞壁磷壁酸的存在以及细胞壁糖组成。肽聚糖类型和细胞壁糖组成可通过快速方法测定。
