Autoinducers Act as Biological Timers in Vibrio harveyi [PDF]
PLoS ONE, 2012 Quorum sensing regulates cell density-dependent phenotypes and involves the synthesis, excretion and detection of so-called autoinducers. Vibrio harveyi strain ATCC BAA-1116 (recently reclassified as Vibrio campbellii), one of the best-characterized ...

PLoS Biology, 2019 Vibrio cholerae possesses multiple quorum-sensing (QS) systems that control virulence and biofilm formation among other traits. At low cell densities, when QS autoinducers are absent, V. cholerae forms biofilms.

Microbead-Encapsulated Luminescent Bioreporter Screening of P. aeruginosa via Its Secreted Quorum-Sensing Molecules [PDF]
BiosensorsPseudomonas aeruginosa is an opportunistic Gram-negative bacterium that remains a prevalent clinical and environmental challenge. Quorum-sensing (QS) molecules are effective biomarkers in pinpointing the presence of P. aeruginosa.

Quorum regulated latent environmental cells of toxigenic Vibrio cholerae and their role in cholera outbreaks [PDF]
Gut PathogensBackground Diverse bacterial group behaviors are controlled by quorum sensing, a regulatory network of bacterial gene expression based on cell density, and involving communication through chemical signal molecules called autoinducers.

Black Queen Hypothesis, partial privatization, and quorum sensing evolution.
PLoS ONE, 2022 Microorganisms produce costly cooperative goods whose benefit is partially shared with nonproducers, called 'mixed' goods. The Black Queen Hypothesis predicts that partial privatization has two major evolutionary implications.

Pharmaceuticals, 2023 Autoinducers AI-1 and AI-2 play an important role in bacterial quorum sensing (QS), a form of chemical communication between bacteria. The autoinducer N-octanoyl-L-Homoserinehomoserine lactone (C8-HSL) serves as a major inter- and intraspecies ...

Journal of Pure and Applied Microbiology, 2022 Quorum sensing (QS) is a type of cell-to-cell communication that is influenced by an increase in signaling molecules known as autoinducers, which is correlated to the increase in the density of microbial communities. In this review, we aim to discuss and

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 ...

Attenuation of Pseudomonas aeruginosa Virulence by Pomegranate Peel Extract
Microorganisms, 2022 Pseudomonas aeruginosa is an opportunistic pathogen often responsible for biofilm-associated infections. The high adhesion of bacterial cells onto biotic/abiotic surfaces is followed by production of an extracellular polysaccharidic matrix and formation ...
