Regulatory Mechanisms and Physiological Impacts of Quorum Sensing in Gram-Negative Bacteria
Xiaobing Chu, Qiwen Yang
Abstract
The Quorum sensing (QS) system is a widely existing communication mechanism, which regulates bacterial community behaviors and the expression of specific genes. The most common pathogenic bacteria in clinical infections are gram-negative bacteria, and QS plays an important regulatory role in the production of virulence factors and development of antibiotic resistance. This article reviews the QS systems of gram-negative bacteria and provides an overview of how they regulate their physiological functions.
