Inhibition of quorum sensing-controlled virulence factor production in Pseudomonas aeruginosa by Quercus infectoria gall extracts

BACKGROUND AND OBJECTIVES This study was designed to evaluate the activity of Quercus infectoria galls extract (QIFGE) on virulence factor production and inhibition of quorum sensing (QS) in Pseudomonas aeruginosa. MATERIALS AND METHODS Minimum inhibitory concentration (MIC) of QIFGE against 5 strains of P. aeruginosa was determined. The extract at sub-MIC was used to determine biofilm format...

Low concentrations of local honey modulate ETA expression, and quorum sensing related virulence in drug-resistant Pseudomonas aeruginosa recovered from infected burn wounds

Objective(s): Honey’s ability to kill microorganisms and even eradication of chronic infections with drug-resistant pathogens has been documented by numerous studies. The present study is focused on the action of honey in its sub-inhibitory levels to impact on the pathogens coordinated behaviors rather than killing them. Materials and Methods:</strong...

Effect of Cinnamon Oil on Quorum Sensing-Controlled Virulence Factors and Biofilm Formation in Pseudomonas aeruginosa

Quorum sensing (QS) is a system of stimuli and responses in bacterial cells governed by their population density, through which they regulate genes that control virulence factors and biofilm formation. Despite considerable research on QS and the discovery of new antibiotics, QS-controlled biofilm formation by microorganisms in clinical settings has remained a problem because of nascent drug res...

E!ects of Allicin on the Formation of Pseudomonas aeruginosa Biofilm and the Production of Quorum-Sensing Controlled Virulence Factors

"e Gram-negative Pseudomonas aeruginosa bacterial pathogen is reputed for its resistance to multiple antibiotics, and this property is strongly associated with the development of biofilms. Bacterial biofilms form by aggregation of microorganisms on a solid surface and secretion of an extracellular polysaccharide substances that acts as a physical protection barrier for the encased bacteria. In ...
