Regulatory Mechanisms between Quorum Sensing and Virulence in .

is a foodborne pathogen that causes enterogastritis among humans, livestock and poultry, and it not only causes huge economic losses for the feed industry but also endangers public health around the world. However, the prevention and treatment of infection has remained poorly developed because of its antibiotic resistance. Bacterial quorum sensing (QS) system is an intercellular cell-cell communication mechanism involving multiple cellular processes, especially bacterial virulence, such as biofilm formation, motility, adherence, and invasion. Therefore, blocking the QS system may be a new strategy for infection independent of antibiotic treatment. Here, we have reviewed the central role of the QS system in virulence regulation of and summarized the most recent advances about quorum quenching (QQ) in virulence attenuation during infection. Unraveling the complex relationship between QS and bacterial virulence may provide new insight into the therapy of pathogen infection.
