Cyanidin inhibits quorum signalling pathway of a food borne opportunistic pathogen.

ABSTRACT: Quorum sensing (QS) is the process of population dependent cell to cell communication used by bacteria to regulate their phenotypic characteristics. Key virulence factors that determine the bacterial pathogenicity and food spoilage were found to be regulated by QS mechanism. Hence, disrupting the QS signaling pathway could be an attractive strategy to manage food borne pathogens. In the current study, QS inhibitory activity of a naturally occurring anthocyanin-cyanidin and its anti-biofilm property were assessed against an opportunistic pathogen Klebsiella pneumoniae, using a bio-sensor strain. Further, QS inhibitory property of a naturally occurring anthocyanin cyanidin was further confirmed using in-silico techniques like molecular docking and molecular dynamics simulation studies. Cyani
