Journal of Genetic Engineering and Biotechnology, 2018 The present study was intended to optimize the quorum sensing inhibitory action of Solanum torvum root extract against Chromobacterium violaceum. Factors such as bacterial density, frequency of administration and concentration of extract were analysed ...

Quorum-Sensing Inhibition by Gram-Positive Bacteria
Microorganisms, 2022 The modern paradigm assumes that interspecies communication of microorganisms occurs through precise regulatory mechanisms. In particular, antagonism between bacteria or bacteria and fungi can be achieved by direct destruction of the targeted cells ...

High yield expression of an AHL-lactonase from Bacillus sp. B546 in Pichia pastoris and its application to reduce Aeromonas hydrophila mortality in aquaculture [PDF]
, 2010 Background Aeromonas hydrophila is a serious pathogen and can cause hemorrhagic septicemia in fish. To control this disease, antibiotics and chemicals are widely used which can consequently result in "superbugs" and chemical accumulation in the food ...

Engineering quorum quenching enzymes: progress and perspectives [PDF]
Biochemical Society Transactions, 2019 Abstract Quorum sensing is a key contributor to the virulence of many important plant, animal and human pathogens. The disruption of this signalling—a process referred to as ‘quorum quenching’—is a promising new approach for controlling microbial pathogens.

Reviewing Microbial Behaviors in Ecosystems Leading to a Natural Quorum Quenching Occurrence
Brazilian Archives of Biology and Technology, 2017 Quorum sensing is considered one of the most important discoveries in cell-to-cell communication. Although revealed in Bacteria, it has been identified as well as a mechanism present in the other two domains, Eukaryota and Archaea.

Targeting virulence not viability in the search for future antibacterials [PDF]
, 2014 New antibacterials need new approaches to overcome the problem of rapid antibiotic resistance. Here we review the development of potential new antibacterial drugs that do not kill bacteria or inhibit their growth, but combat disease instead by targeting ...

Quorum-quenching microbial infections: mechanisms and implications [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2007 The discovery of antibiotics early in the past century marked the beginning of active control and prevention of infectious microbial diseases. However, extensive use of antibiotics has also unavoidably resulted in the emergence of ‘superbugs’ that resist conventional antibiotics.

Microbial Biotechnology, 2023 Virulence factor modulating (VFM) is a quorum sensing (QS) signal shared by and specific to Dickeya bacteria, regulating the production of plant cell wall degrading enzymes (PCWDEs) and virulence of Dickeya. High polarity and trace of VFM signal increase
