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...

MetabolomicsMetabolomics reveals plasma profiles of Mycoplasma synovise infection with different virulence

Mycoplasma synovise (MS) is a prominent pathogen of poultry, causing considerable economic pressure to the poultry industry. Although we have a basic understanding of MS infection, the research on the pathogenicity and interactions between host and MS especially the metabolic bases of MS infectio...

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...

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...

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...

MetabolomicsDeep longitudinal multi-omics analysis of Bordetella pertussis cultivated in bioreactors highlights medium starvations and transitory metabolisms, associated to vaccine antigen biosynthesis variations and global virulence regulation

Bordetella pertussis is the bacterial causative agent of whooping cough, a serious respiratory illness. An extensive knowledge on its virulence regulation and metabolism is a key factor to ensure pertussis vaccine manufacturing process robustness. The aim of this study was to refine our ...

MetabolomicsIntegrated Proteomic and Metabolomic Profiling Reveals Potential Virulence Factors and Secondary Metabolites in the Secretome of Fusarium verticillioides

Fusarium verticillioides (F. verticillioides) is an important fungal pathogen known to infect a variety of economically critical crops, especially maize, causing substantial yield reductions and economic losses worldwide. In addition to its direct damage to agricultural productivity, F. verticill...

MetabolomicsFoHsf1 reprograms central metabolism via caffeine and vitamin D2 to modulate development and virulence of Fusarium oxysporum on Polygonatum kingianum
Root rot has severely affected the yield and quality of Polygonatum kingianum, and Fusarium oxysporum has been identified as the primary causal agent. To explore the virulence mechanisms of this pathogen, we performed a functional characterization of FoHsf1, a gene encoding a heat shock transcriptio...

TranscriptomicsSmall RNA pyrosequencing in the protozoan parasite Entamoeba histolytica reveals strain-specific small RNAs that target virulence genes
We provided a full spectrum analysis for E. histolytica AGO2-2 associated 27nt small RNAs. Additionally, comparative analysis of small RNA populations from virulent and non-virulent amebic strains indicates that small RNA populations may regulate virulence genes. AGO2-2 bound small RNAs from E. hist...

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...
