Quorum sensing is a cell-to-cell communication system that exists widely in the microbiome and is related to cell density. The high-density colony population can generate a sufficient number of small molecule signals, activate a variety of downstream cellular processes including virulence and drug resistance mechanisms, tolerate antibiotics, and harm the host. This article gives a general introduction to the current research status of microbial quorum-sensing systems, focuses on the role of quorum-sensing systems in regulating microbial resistance mechanisms, such as drug efflux pump and microbial biofilm formation regulation, and discusses a new strategy for the treatment of drug-resistant bacteria proposed by using quorum quenching to prevent microbial resistance.
群体感应是一种广泛存在于微生物群落中的细胞间通信系统，与细胞密度相关。高密度的菌落群体能够产生足够数量的小分子信号，激活包括毒力和耐药机制在内的多种下游细胞过程，耐受抗生素，并对宿主造成损害。本文对微生物群体感应系统的当前研究现状进行了概述，重点关注群体感应系统在调节微生物耐药机制中的作用，如药物外排泵和微生物生物膜形成调控，并探讨了利用群体淬灭预防微生物耐药性从而治疗耐药菌的新策略。
