变异链球菌耐酸分子机制的研究进展

Research advancement about the molecular mechanism of acid tolerance of Streptococcus mutans

耐酸性是变异链球菌重要的致龋因素之一,虽然其分子机制尚不明了,但目前己分离、测序并克隆了数个相关基因。下面就己发现的影响变异链球菌耐酸性的基因及其结构、功能和可能的作用机制作一综述。

Acid tolerance is one of the main cariogenesis factors of Streptococcus mutans. Although the molecular mechanism is not clear now, several relevance genes have been separated, sequenced and cloned. This is a review about these related genes and their possible mechanism of action.
