变形链球菌遗传Ⅰ型JBP和Ⅲ型6715表面形态的电镜观察

Electron Microscopic Observation of Cell Surface Forms in Streptococcus mutans and Streptococcus sobrinus

对变形链球菌遗传Ⅰ型Ｓ．ｍｕｔａｎｓＪＢＰ（ｃ）和Ⅲ型Ｓ．ｓｏｂｒｉｎｕｓ６７１５（ｇ）菌体表面形态的电镜观察显示，仅遗传Ⅲ型Ｓ．ｓｏｂｒｉｎｕｓ６７１５（ｇ）菌体表面存在毛状外膜。但此差异形成的机理以及是否影响变形链球菌的粘附尚需进一步探讨。

The authors have observed cell surface forms of Streptococcus mutans JBP(serotype c) and Streptococcus sobrinus 6715(serotype g)by electron microscopy. The results showed that only the cell surface of Streptococcus sobrinus has fuzzy coat. Further studies will be required to prove the differences of their forms and the mechanism affecting both bacterial adhesion.
