MetabolomicsHeat drives tomato bacterial wilt through enhanced pathogen virulence and rhizosphere microbiome and metabolic shifts
Bacterial wilt caused by Ralstonia solanacearum is globally widespread and strongly associated with elevated temperature, yet the ecological mechanisms underlying temperature-driven disease outbreaks remains unclear. Here, we show that high temperature promotes bacterial wilt by reconfiguring the to...

MetabolomicsIdentification of BolA protein reveals a novel virulence factor in Klebsiella pneumoniae that contributes to liver abscess in mice

BolA has been characterized as an important transcriptional regulator, which is induced in the stationary phase of growth and is often associated with bacterial virulence. This study was initiated to elucidate the role of the BolA in the virulence of K. pneumoniae. Using a mous...

MetabolomicsOriginal data of bacterial antibiotic resistance lipidomics
Plasmid-mediated dissemination of mcr genes has severely compromised colistin efficacy, necessitating adjuvants that restore antibacterial potency without exacerbating toxicity. Despite their essential roles in bacterial survival and virulence, metal ion acquisition systems remain underexplored as t...

MetabolomicsSalmonella Typhimurium reprograms macrophage metabolism via T3SS effector SopE2 to promote intracellular replication and virulence

Salmonella Typhimurium establishes systemic infection by replicating in host macrophages. Here we show that macrophages infected with S. Typhimurium exhibit upregulated glycolysis and decreased serine synthesis, leading to accumulation of glycolytic intermediates. The effects on...

MetabolomicsL-serine enables reducing the virulence of Acinetobacter baumannii and modulating the SIRT1 pathway to eliminate the pathogen

The emergence of high-virulent Acinetobacter baumannii strains increases the mortality of patients and seriously affects their prognosis, which motivates us to explore novel ways to control such infections. In this study, gas chromatography-mass spectrometry was adopted to explore the me...

MetabolomicsRcrR: A Multifunctional Transcriptional Regulator Orchestrating the cariogenic virulence of Streptococcus mutans

We systematically investigated RcrR's contribution to cariogenic virulence using isogenic wild-type, DeltarcrR deletion mutant, and complemented strains. We assessed bacterial growth, biofilm architecture, acid tolerance, and H+-ATPase activity. To delineate the global regulatory network, we inte...

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...

MetabolomicsReleased palmitic acid–mediated TLR4/NF-κB activation enhances the virulence of Bordetella pertussis MT28 lineage

Whooping cough resurged globally despite the widespread vaccination. A macrolide-resistant (MR) lineage carrying the high-virulence ptxP3 allele, ptxP3 MR-MT28 (MT28), has imposed a substantial burden on pertussis epidemics, while the underlying factors driving its prevalence remain unclear. Thus...

MetabolomicsMycobacterium tuberculosis VadK required for regulation of the methylcitrate cycle and virulence

The evolution of new enzymatic functions is constrained and guided by the architecture of an organism’s metabolic and regulatory networks and environmental constraints. Here, we identify a kinase that has evolved from pyruvate phosphate dikinase. Through biochemical and systems-lev...

MetabolomicsBacterial extracellular vesicles as recyclable nutrient reservoirs

Bacterial extracellular vesicles (EVs) are known to mediate intercellular communication, virulence, and immune modulation. Here we show that bacteria can utilise EVs also as recyclable nutrient reservoirs. Using Bacillus cereus as a model organism, we demonstrate that EVs exhibit distin...
