REVIEW ON ANTI QUORUM SENSING ACTIVITY IN PSEUDOMONAS AERUGINOSA USING PLANTS EXTRACTS

N. BANU1 AND R. NANCY IMMACULATE MARY

Abstract

Plant research has profited a lot of momentum in the medical field for the discovery of new, safe, and effective remedies. In the context of antimicrobial research, various plant sources have been discovered with the potential to disrupt bacterial quorum sensing (QS), which plays a key role in the regulation of virulence in many Gram positive and Gram negative bacteria. Pseudomonas aeruginosa, a Gram negative bacterium, is known to produce multiple QS systems that control the expression of virulence determinants and biofilm development in this pathogen. Hence, the inhibition of QS has been pursued as a promising therapy for the treatment of drug resistant Pseudomonas infections. A comprehensive review of the research data available for plant products as QS inhibitors of the organism has been presented here, while further suggesting the future prospects for these inhibitors.
