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...

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...

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...

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...

MetabolomicsPeroxin Pex8 couples stress responses, antifungal tolerance and virulence regulation in Candida albicans

Candida albicans, a World Health Organization critical-priority fungal pathogen, represents the predominant cause of candidemia. Therapeutic failure is sometimes driven by antifungal tolerance, a phenotype distinct from resistance, whose underlying mechanisms remain incompletely defined....

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...

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...

TranscriptomicsTranscriptomic characterization of a virulence-deficient phosphatidylcholine-negative Agrobacterium tumefaciens mutant
To learn more about the global effects of phosphatidylcholine (PC)-deficiency in A. tumefaciens, we performed transcriptomic studies comparing the wild type and a PC-deficient DpmtA Dpcs mutant. We expanded the number of affected virulence genes and showed that the loss of PC was correlated with alt...

ModelsiRP1443REG - Ralstonia solanacearum GMI1000 Virulence regulatory network
We reconstructed the Virulence Regulatory Network (VRN) of R. solanacearum strain GMI1000 by collecting bibliographical information based on genetic and genomic studies, including three transcriptomic studies. The reconstructed R. solanacearum VRN comprises 712 genes including 29 genes coding for tr...

TranscriptomicsP. falciparum Heterochromatin Protein 1 Marks Genomic Loci Linked to Phenotypic Variation of Exported Virulence Factors
Epigenetic processes are the main conductors of phenotypic variation in eukaryotes. The malaria parasite Plasmodium falciparum employs antigenic variation of the major surface antigen PfEMP1, encoded by 60 var genes, to evade acquired immune responses. PfEMP1 also mediates sequestration of infected ...
