MetabolomicsBurkholderia cenocepacia-mediated inhibition of Staphylococcus aureus growth and biofilm formation

Staphylococcus aureus asymptomatically colonizes the nasal cavity and pharynx of up to 60% of the human population and, as an opportunistic pathogen, can breach its normal habitat, resulting in life-threatening infections. S. aureus infections are of additional concern for populations with impair...

MetabolomicsValine potentiates cefoperazone-sulbactam to kill methicillin resistant Staphylococcus aureus

Metabolic state-reprogramming approach was extended from Gram-negative bacteria to Gram-positive bacterium methicillin-resistant Staphylococcus aureus (MRSA) for identifying desired reprogramming metabolites to synergize existing antibiotic killing to MRSA. Metabolomics comparison between MRSA an...

MetabolomicsNitrate Reductase NarGHJI Modulates Vancomycin Susceptibility by Coordinating Cell Wall Remodeling and Agmatine Metabolism in Staphylococcus aureus
Staphylococcus aureus is a ubiquitous pathogen responsible for a wide range of severe infections. Our previous work established that the nitrate reductase NarGHJI modulates bacterial pathogenicity through regulation of the agr system, yet its role in antibiotic resistance remains poorly understood. ...

MetabolomicsSystematic identification of bacterial factors driving Staphylococcus aureus intracellular lifestyle in non-professional phagocytes

Staphylococcus aureus is a major human pathogen responsible for severe infections. While traditionally described as extracellular, increasing evidence establishes S. aureus as a facultative intracellular pathogen. Intracellularity contributes to immune evasion, dissemination, and antibiotic failu...

MetabolomicsA novel targeted/untargeted GC-Orbitrap metabolomics methodology applied to Candida albicans and Staphylococcus aureus biofilms

INTRODUCTION: Combined infections from Candida albicans and Staphylococcus aureus are a leading cause of death in the developed world. Evidence suggests that Candida enhances the virulence of Staphylococcus - hyphae penetrate through tissue bar...

MetabolomicsCiprofloxacin-induced metabolic disruption and stringent response drives persistent small-colony variants in Staphylococcus aureus

Antibiotic treatment failure in Staphylococcus aureus infections is frequently associated with antimicrobial resistance or the emergence of small-colony variants (SCVs), a metabolically quiescent phenotype that complicates infection management. Here, we show that ciprofloxacin induces a stable SC...

MetabolomicsThe killing mechanism of teixobactin against methicillin-resistant Staphylococcus aureus (MRSA): An untargeted metabolomics study

The discovery of antibiotics has led to the effective treatment of bacterial infections that were otherwise fatal and has had a transformative effect on modern medicine. Teixobactin is an unusual depsipeptide natural product that was recently discovered from a previously unculturable soil bacteri...

MetabolomicsDiscovery of isokurarinone as an ATCase-Engaging Lead with potent activity against methicillin-resistant Staphylococcus aureus

The global proliferation of methicillin-resistant Staphylococcus aureus (MRSA) persists as a significant contributor to challenging infections, highlighting the urgent necessity for therapies that utilize novel mechanisms. Aspartate transcarbamoylase (ATCase), which catalyzes the initial committe...

MetabolomicsComparative analysis of the adaptation of Staphylococcus aureus to internalization by different types of human non-professional phagocytic host cells (NMR assay)
Staphylococcus aureus is a human pathogen that can cause a wide range of diseases. Although formerly regarded as extracellular pathogen, it has been shown that S. aureus can also be internalized by host cells and persist within these cells. In the present study, we comparatively analyzed survival an...

MetabolomicsComputational Ranking of Yerba Mate Small Molecules Based on Their Predicted Contribution to Antibacterial Activity against Methicillin-Resistant Staphylococcus aureus
The aqueous extract of yerba mate, a South American tea beverage made from Ilex paraguariensis leaves, has demonstrated bactericidal and inhibitory activity against bacterial pathogens, including methicillin-resistant Staphylococcus aureus (MRSA). The gas chromatography-mass spectrometry (GC-MS) ana...
