Project title: Modulation of quorum sensing in selected Gram-negative pathogenic bacteria using novel molecules

Summary: The aim of this study is to assess the modulation of quorum sensing Chromobacterium violaceum and Pseudomonas aeruginosa in presence of inhibitors and inducer by time dependent gene regulation mechanism. Further to establish quorum sensing targeted antibiotic therapy using selected antibiotics and novel quorum sensing inhibitors. Cuurently there is high interest in manipulating bacterial quorum sensing signaling systems for diverse applications such as ecological control in agriculture, food industry and antivirulence in medicine. We want to study the modulation of the quorum sensing mediated genes in the presence of inhibitors and inducers at a temporal scale. Hence, this study proposes to determine novel strategies involving quorum sensing mediated targets using certain inhibitory molecules for the improved drug efficacy by identifying the genes regulated in the Gram-negative pathogen system. Naturally derived quorum sensing inhibitors are molecules that agonize or antagonize quorum sensing which can structurally mimic the AHLs/ signalling molecules, and such competitive binding is effective to block activation of AHL-mediated virulence in the opportunistic pathogens. In addition to that, quorum sensing inhibitors can also affect the integrity of biofilms and thus, will make the bacteria more susceptible to conventional antibiotics. This serves as an advantage as it can help to minimize the possibility of the bacteria from becoming resistant. The knowledge generated may be applied in healthcare set up for the management of Chromobacterium violaceumPseudomonas aeruginosaAcinetobacter baumannii and similar bacterial infections.
