Inhibition of Pseudomonas aeruginosa Quorum Sensing by Curcuma xanthorrhiza Roxb. Extract [PDF]
Journal of Pure and Applied Microbiology, 2019 Microorganisms such as Pseudomonas aeruginosa have always been adaptable in surviving the harsh environment such as antimicrobial agents via the quorum sensing (QS) mechanism.

, 2019 Quorum sensing is the intercellular communication used by a bacterial population, once it reaches a certain threshold, to collectively synchronize the expression of pathogenic traits, such as biofilm formation, swarming motility, and the production of virulence factors. This coordinated behaviour is mediated via small molecules called auto-inducers. In

Quorum Sensing of Periodontal Pathogens
Acta Stomatologica Croatica, 2015 The term ‘quorum sensing’ describes intercellular bacterial communication which regulates bacterial gene expression according to population cell density. Bacteria produce and secrete small molecules, named autoinducers, into the intercellular space.

Proceedings of the National Academy of Sciences, 2013 When the Hawaiian bobtail squid rises from the sand each evening to hunt, it swims cloaked from detection by predators and prey because it casts no moonlight shadow, a trick it owes to compartments full of glowing bacteria on its underside. It tunes these mini-floodlights to the right intensity using light sensors on its back, adjusting a shutter on ...

Quorum Sensing and Phytochemicals [PDF]
International Journal of Molecular Sciences, 2013 Most infectious diseases are caused by bacteria, which proliferate within quorum sensing (QS)-mediated biofilms. Efforts to block QS in bacteria and disrupt biofilms have enabled the identification of bioactive molecules that are also produced by plants.

Quorum Sensing and Quorum Quenching with a Focus on Cariogenic and Periodontopathic Oral Biofilms
Microorganisms, 2022 Numerous in vitro studies highlight the role of quorum sensing in the pathogenicity and virulence of biofilms. This narrative review discusses general principles in quorum sensing, including Gram-positive and Gram-negative models and the influence of ...

Quorum sensing in group A Streptococcus [PDF]
Frontiers in Cellular and Infection Microbiology, 2014 Quorum sensing (QS) is a widespread phenomenon in the microbial world that has important implications in the coordination of population-wide responses in several bacterial pathogens. In Group A Streptococcus (GAS), many questions surrounding QS systems remain to be solved pertaining to their function and their contribution to the GAS lifestyle in the ...
