Quorum sensing (QS) is a common method of communication among bacteria. While previous studies have discovered the mechanisms of QS in a variety of pathogenic bacteria, relatively little research has focused on probiotics, such as Bifidobacteria. Recent studies have detected QS signalling molecules in Bifidobacteria, but it remains unclear whether the probiotic properties of Bifidobacteria are mediated by QS. This review aims to provide an overview of the QS system in Bifidobacteria and its role in promoting the secretion of metabolites such as extracellular vesicles and biofilms. The review further examines the inhibition of virulence gene expression by Bifidobacteria QS through the luxS/AI-2 system, as well as its role in promoting host-microbial interactions. Understanding the QS mechanisms of Bifidobacteria can reveal beneficial interactions with hosts, which may facilitate the control of bacterial infections, including therapeutic strategies for intestinal diseases. This knowledge can also help improve gut health, thereby addressing the opportunities and challenges of enhancing the body's nutritional status.
