Abstract: Quorum sensing (QS) is a microbial cell-to-cell communication mechanism that plays a key regulatory role in bacterial virulence factor expression, bioluminescence, spore formation, and biofilm formation. In recent years, researchers have found that QS also exists in the gastro-intestinal tract of livestock and poultry. In view of the significant role of gastro-intestinal microflora in the digestion, physiological metabolisms, and immune functions of animals, research and regulation of gastro-intestinal bacterial QS is of great significance in guaranteeing health and improving production performance. In this paper, the classifications and effects of bacterial QS, and the research findings of gastro-intestinal bacterial QS in different domestic animals was reviewed, and the relevant regulation and potential mechanisms of QS were also introduced, in order to provide reference for the research and application of bacterial QS in livestock and poultry industry.

Key words: quorum sensing, bacteria, livestock and poultry gastro-intestine, livestock and poultry production
