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., Ortori, C. A., Harrison, F., Halliday, N., Emtage, 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.
