MetabolomicsThe patatin-like protein PlpD forms novel structurally dynamic homodimers in the Pseudomonas aeruginosa outer membrane

Members of the Omp85 superfamily of outer membrane proteins (OMPs) found in Gram-negative bacteria, mitochondria and chloroplasts are characterized by a distinctive 16-stranded β-barrel transmembrane domain and at least one periplasmic POTRA domain. All previously studied Omp85 proteins promote c...

MetabolomicsThe influence of Pseudomonas aeruginosa infection on the airway metabolome
Pseudomonas aeruginosa is an environmentally resilient bacterium and an important cause of both acute and chronic infections in people with impaired natural barriers or immunological defences. Chronic respiratory infection with P. aeruginosa is a major cause of morbidity and mortality in people with...

MetabolomicsGenome-scale metabolic modelling of responses to polymyxins in Pseudomonas aeruginosa
Background: Pseudomonas aeruginosa often causes multidrug-resistant infections in immunocompromised patients and polymyxins are often used as the last-line therapy. Alarmingly, resistance to polymyxins has been increasingly reported worldwide recently. To rescue this last-resort class of antibiotics...

MetabolomicsTranscriptomic and Metabolomics Profiling of Phage–Host Interactions between Phage PaP1 and Pseudomonas aeruginosa
The basic biology of bacteriophage–host interactions has attracted increasing attention due to a renewed interest in the therapeutic potential of bacteriophages. In addition, knowledge of the host pathways inhibited by phage may provide clues to novel drug targets. However, the effect of phage on ba...

TranscriptomicsTranscription profiling of Pseudomonas aeruginosa response to low oxygen
In order to understand how Pseudomonas aeruginosa responds to low oxygen we grew strain PAO1 with 3 different oxygen concentrations: 2%, 0.4% and 0% supplemented with nitrate as an electron acceptor. Gene expression under these conditions was compared to that of cells grown with 20% oxygen. Experim...

MetabolomicsUntargeted metabolomics reveals species-specific metabolite production and shared nutrient consumption by Pseudomonas aeruginosa and Staphylococcus aureus

While bacterial metabolism is known to impact antibiotic efficacy and virulence, the metabolic capacities of individual microbes in cystic fibrosis lung infections are difficult to disentangle from sputum samples. Here, we show that untargeted metabolomic profiling of supernatants of multiple str...

TranscriptomicsPseudomonas aeruginosa two-component regulator BfmR controls bacteriophage lysis and DNA release during biofilm development through PhdA
Biofilms are surface-adhered bacterial communities encased in an extracellular matrix composed of polysaccharides, proteins, and extracelluar (e)DNA, with eDNA being required for the formation and integrity of biofilms. Here we demonstrate that the spatial and temporal release of eDNA is regulated b...

MetabolomicsStaphylococcus aureus coagulases increase survival of Pseudomonas aeruginosa during coinfection

Polymicrobial infections involving Staphylococcus aureus are often more severe than single-species infections. S. aureus typically initiates the infection, creating conditions that allow secondary pathogens like Pseudomonas aeruginosa to establish. In this study, we investigate how coagulase prod...

MetabolomicsMetabolic Phenotyping and Strain Characterisation of Pseudomonas aeruginosa Isolates from Cystic Fibrosis Patients Using Rapid Evaporative Ionisation Mass Spectrometry
Rapid evaporative ionisation mass spectrometry (REIMS) is a novel technique for the real-time analysis of biological material. It works by conducting an electrical current through a sample, causing it to rapidly heat and evaporate, with the analyte containing vapour channelled to a mass spectrometer...
