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...

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...

TranscriptomicsA novel extracytoplasmic function (ECF) sigma factor regulates virulence in Pseudomonas aeruginosa
Next to the two-component and quorum sensing systems, cell-surface signaling (CSS) has been recently identified as an important regulatory system in Pseudomonas aeruginosa. CSS senses signals from outside the cell and transmits them into the cytoplasm. It consists of a TonB-dependent outer membrane ...

TranscriptomicsIdentification of MglA-regulated genes reveals novel virulence factors in F. tularensis
The facultative intracellular bacterium Francisella tularensis causes the zoonotic disease tularemia. F. tularensis resides within host macrophages in vivo and this ability is essential for pathogenesis. The transcription factor MglA is required for expression of several Francisella genes that are...

TranscriptomicsDsbA plays a critical and multi-faceted role in the production of secreted virulence factors by Erwinia carotovora
Erwinia carotovora subsp. atroseptica (Eca) is an enterobacterial phytopathogen causing economically-significant soft rot disease. Pathogenesis is mediated by multiple secreted virulence factors, many of which are secreted by the Type II (Out) secretion system. DsbA catalyses the introduction of dis...
