Porphyromonas pasteri and Prevotella nanceiensis in the sputum microbiota are associated with increased decline in lung function in individuals with cystic fibrosis (2022)
Journal Article
Webb, K., Zain, N. M. M., Stewart, I., Fogarty, A., Nash, E. F., Whitehouse, J. L., …Barr, H. L. (2022). Porphyromonas pasteri and Prevotella nanceiensis in the sputum microbiota are associated with increased decline in lung function in individuals with cystic fibrosis. Journal of Medical Microbiology, 71(2), Article 001481. https://doi.org/10.1099/jmm.0.001481

Although anaerobic bacteria exist in abundance in cystic fibrosis (CF) airways, their role in disease progression is poorly understood. We hypothesized that the presence and relative abundance of the most prevalent, live, anaerobic bacteria in sputum...

(2021). 2-Alkyl-4-quinolone quorum sensing molecules are biomarkers for culture-independent Pseudomonas aeruginosa burden in adults with cystic fibrosis. Journal of Medical Microbiology, 70(10), https://doi.org/10.1099/jmm.0.001420

Introduction. Pseudomonas aeruginosa produces quorum sensing signalling molecules including 2-alkyl-4-quinolones (AQs), which regulate virulence factor production in the cystic fibrosis (CF) airways. Hypothesis/Gap statement. Culture can lead to cond...

Novel detection of specific bacterial quorum sensing molecules in saliva: Potential non-invasive biomarkers for pulmonary Pseudomonas aeruginosa in cystic fibrosis (2021)
Journal Article
Webb, K., Cámara, M., Zain, N. M. M., Halliday, N., Bruce, K. D., Nash, E. F., …Barr, H. L. (2022). Novel detection of specific bacterial quorum sensing molecules in saliva: Potential non-invasive biomarkers for pulmonary Pseudomonas aeruginosa in cystic fibrosis. Journal of Cystic Fibrosis, 21(4), 626-629. https://doi.org/10.1016/j.jcf.2021.08.030

Pseudomonas aeruginosa produces specific signalling molecules, 2-alkyl-4-quinolones (AQs) that are detectable in the sputum of adults with cystic fibrosis (CF) and who have pulmonary infection with this opportunistic pathogen. This study aimed to det...

Introduction : Pseudomonas aeruginosa is an important respiratory pathogen in cystic fibrosis (CF), which is associated with an accelerated decline in lung function, frequent pulmonary exacerbations and increased mortality. P. aeruginosa produces in...

Diagnostic and prognostic significance of systemic alkyl quinolones for P. aeruginosa in cystic fibrosis: a longitudinal study (2016)
Journal Article
Barr, H. L., Halliday, N., Barrett, D. A., Williams, P., Forrester, D. L., Peckham, D., …Fogarty, A. W. (2017). Diagnostic and prognostic significance of systemic alkyl quinolones for P. aeruginosa in cystic fibrosis: a longitudinal study. Journal of Cystic Fibrosis, 16(2), 230-238. https://doi.org/10.1016/j.jcf.2016.10.005

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.

Scientific Reports, 5, Article 7649. https://doi.org/10.1038/srep07649

The Cystic Fibrosis (CF) lung harbors a complex, polymicrobial ecosystem, in which Pseudomonas aeruginosa is capable of sustaining chronic infections, which are highly resistant to multiple antibiotics. Here, we investigate the phenotypic and genotyp...
