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...

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...

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...

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...

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...

TranscriptomicsIdentify genes regulated by zip-2 in absence and presence of P. aeruginosa PA14 infection at 4h
Very little is known about how animals discriminate pathogens from innocuous microbes. To address this question, we examined infection-response gene induction in the nematode Caenorhabditis elegans. We focused on genes that are induced in C. elegans by infection with the bacterial pathogen Pseudomon...

TranscriptomicsDefinition of the Pseudomonas aeruginosa Anr and Dnr Regulons
The anaerobic metabolism of the opportunistic pathogen Pseudomonas aeruginosa is important for growth and survival during persistent infections. The two Fnr-type transcription factors Anr and Dnr regulate different parts of the underlying network. Both are proposed to bind to a non-distinguishable D...

TranscriptomicsTranscriptional and proteomic response of Pseudomonas aeruginosa PAO1 to spaceflight conditions involves Hfq regulation and reveals a role for oxygen
Characterization of bacterial behavior in the microgravity environment of spaceflight is of importance towards risk assessment and prevention of infectious disease during long-term missions. Further, this research field unveils new insights into connections between low fluid-shear regions encountere...

TranscriptomicsThe effect of IAN on P. aeruginosa virulence
Intercellular signal indole and its derivative hydroxyindoles inhibit Escherichia coli biofilm and diminish Pseudomonas aeruginosa virulence. However, indole and bacterial indole derivatives were unstable in microbial community due to the widespread of diverse oxygenases that could quickly degrade ...
