Background
Pulmonary P. aeruginosa infection is associated with poor outcomes in cystic fibrosis (CF) and early diagnosis is challenging, particularly in those who are unable to expectorate sputum. Specific P. aeruginosa 2-alkyl-4-quinolones are det... Read More about Diagnostic and prognostic significance of systemic alkyl quinolones for P. aeruginosa in cystic fibrosis: a longitudinal study.

The fitness burden imposed by synthesising quorum sensing signals (2016)
Journal Article
Ruparell, A., Dubern, J.-F., Ortori, C. A., Harrison, F., Halliday, N., Emtage, A., Ashawesh, M., Laughton, C. A., Diggle, S. P., Williams, P., Barrett, D. A., & Hardie, K. R. (2016). The fitness burden imposed by synthesising quorum sensing signals. Scientific Reports, 6, Article 33101. https://doi.org/10.1038/srep33101

It is now well established that bacterial populations utilize cell-to-cell signaling (quorum-sensing, QS) to control the production of public goods and other co-operative behaviours. Evolutionary theory predicts that both the cost of signal productio... Read More about The fitness burden imposed by synthesising quorum sensing signals.

In Pseudomonas aeruginosa, quorum sensing (QS) regulates the production of secondary metabolites, many of which are antimicrobials that impact on polymicrobial community composition. Consequently, quenching QS modulates the environmental impact of P.... Read More about Biotic inactivation of the Pseudomonas aeruginosa quinolone signal molecule.

Bacteria clustering by polymers induces the expression of quorum sense controlled phenotypes. Nature Chemistry, 5(12), https://doi.org/10.1038/nchem.1793

Bacteria deploy a range of chemistries to regulate their behaviour and respond to their environment. Quorum sensing is one mean by which bacteria use chemical reactions to modulate pre-infection behaviour such as surface attachment. Polymers that can...
