Anti-quorum sensing effects of Licochalcone A and Epigallocatechin-3-gallate against Salmonella Typhimurium from poultry sources
Quorum sensing (QS) is a cell density-dependent mechanism used by many pathogenic bacteria for regulating virulence gene expression. Inhibition or interruption of QS by medicinal plant remedies has been suggested as a new strategy for fighting against antibiotic-resistant bacteria. This study aimed to assess the impact of sub-inhibitory concentrations of licochalcone A (LAA) and epigallocatechi...
متن کاملQuorum Sensing in Microbial Virulence
Cell-to cell communication occurs via a signaling pathway referred to as quorum sensing. There are four main types of these systems according to the chemical nature of signal molecules used by microorganisms to elicit expression of target genes in response to environmental stimuli or need of microbial communities. Type I system acts by using acyl homoserine lactones as signals to trigger the ex...
متن کاملLow 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...
متن کاملQuorum Sensing Signal Production and Microbial Interactions in a Polymicrobial Disease of Corals and the Coral Surface Mucopolysaccharide Layer
Black band disease (BBD) of corals is a complex polymicrobial disease considered to be a threat to coral reef health, as it can lead to mortality of massive reef-building corals. The BBD community is dominated by gliding, filamentous cyanobacteria with a highly diverse population of heterotrophic bacteria. Microbial interactions such as quorum sensing (QS) and antimicrobial production may be in...

Abstract Introduction: Bacteria communicate with each other by using molecular chemical signal, which are called autoinducer. By the increase of concentration of these signals, which is the result of increase cellular density, they coordinate gene expression in a microbial community. This process is called Quorum sensing. Considering the importance of urine tract infections prominent role of Qu...
