This study revealed the antipathogenic potential of natural compounds present in the edible fruits against urinary pathogen Serratia marcescens by using quorum sensing inhibition (QSI). The serum resistance assay was adopted to examine the immunomodulatory effects of QSI compounds to fight against bacterial infections.
Quorum sensing (QS) is a process of cell-cell communication mechanism occurs between the bacterial cells through the secretary signal molecules. This QS mechanism has been shown to control over the expression of various genes responsible for the production of virulence factors in several bacterial pathogens. Hence, the present study was intended to evaluate(More)
Drugs have been discovered in the past mainly either by identification of active components from traditional remedies or by unpredicted discovery. A key motivation for the study of structure based virtual screening is the exploitation of such information to design targeted drugs. In this study, structure based virtual screening was used in search for(More)
BACKGROUND To find out an alternative strategy to antibiotic usage against bacterial infection. MATERIALS AND METHODS The purpose of this study is to describe the quorum-sensing (QS) inhibitory activity of edible plants and fruits against N-acyl-homoserine lactone (AHL)-mediated violacein production in Chromobacterium violaceum and virulence factor(More)
The focal intent of this study was to find out an alternative strategy for the antibiotic usage against bacterial infections. The quorum sensing inhibitory (QSI) activity of marine sponges collected from Palk Bay, India was evaluated against acyl homoserine lactone (AHL) mediated violacein production in Chromobacterium violaceum (ATCC 12472), CV026 and(More)
