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 ...

Specific quorum sensing-disrupting activity (A(QSI)) of thiophenones and their therapeutic potential [PDF]
, 2015 Disease caused by antibiotic resistant pathogens is becoming a serious problem, both in human and veterinary medicine. The inhibition of quorum sensing, bacterial cell-to-cell communication, is a promising alternative strategy to control disease. In this

Biofilm dispersion and quorum sensing [PDF]
Current Opinion in Microbiology, 2014 Biofilm development and quorum sensing (QS) are closely interconnected processes. Biofilm formation is a cooperative group behaviour that involves bacterial populations living embedded in a self-produced extracellular matrix. QS is a cell-cell communication mechanism that synchronizes gene expression in response to population cell density. Intuitively,
