Research Abstract

Streptococcus mutans uses two-component signal transduction systems (TCSs) to monitor and respond to changes of various environmental conditions in human oral cavity. However, mechanisms of TCSs in stress tolerance have been still unknown. In this study, we identified 14 components of TCSs involved in resistance to chlorhexidine, a medicated component of tooth powder.
