Abstract:Infections of Pseudomonas aeruginosa are of great concern because of its increasing resistance towards conventional antibiotics. Quorum sensing system of P. aeruginosa acts as a global regulator of almost all the virulence factors and majorly its biofilm formation. In the present study, quenching of QS system of P. aeruginosa has been explained with bioactives from bacteria associated with the coral Acropora digitifera. Isolated bioactives inhibited the expression of various virulence traits of P. aeruginosa like biofilm formation, and the production of extracellular enzymes like protease and elastase. This study also emphasises the potential of coral associated bacteria in producing bioactive agents with anti-pathogenic properties.
Keywords:Quorum sensing  Pseudomonas aeruginosa  Coral associated bacteria  Biofilm  Anti-QS  Quorum sensing inhibitor
