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....

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...

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...

ProteomicsThe Cryptosporidium signaling kinase CDPK5 plays an important role in male gametogenesis and parasite virulence
The protozoan parasite Cryptosporidium is a leading cause of diarrhea associated mortality in young children. The parasite’s lifecycle involves a highly coordinated and timely progression from asexual proliferative to sexual stages leading to formation of the transmissible oocyst. Underlying molecul...

MetabolomicsAnalysis of the Mechanism of Pathogenicity Decline in Alternaria alternata f. sp. mali Mediated by the Mycovirus AaCV1
Apple leaf blotch disease caused by Alternaria alternata is a major fungal disease affecting apple production. To investigate the molecular mechanisms underlying virus-induced hypovirulence, metabolomic profiling was performed on A. alternata strains under different genetic and treatment conditions,...

TranscriptomicsChIP-chip of HA-tagged Lsr2 in Mycobacterium tuberculosis and Mycobacterium smegmatis
Bacterial nucleoid-associated proteins play important roles in chromosome organization and global gene regulation. We find that Lsr2 of Mycobacterium tuberculosis is a novel nucleoid-associated protein that specifically binds AT-rich regions of the genome, including regions encoding major virulence ...

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...

TranscriptomicsDetection of virulence and antibiotic resistance gene families
Emerging known and unknown pathogens create profound threats to public health. Platforms for rapid detection and characterization of microbial agents are critically needed to prevent and respond to disease outbreaks. Available detection technologies cannot provide broad functional information about ...

TranscriptomicsSurface sensing in Vibrio parahaemolyticus triggers a programme of gene expression that promotes colonization and virulence
Vibrio parahaemolyticus senses surfaces via impeded rotation of its polar flagellum. We have exploited this surface-sensing mechanism to trick the organism into thinking it is on a surface when it is growing in liquid. This facilitated studies of global gene expression in a way that avoided many of ...

ProteomicsQuantitative exoproteomic analysis reveals a virulence-regulating mechanism by an AraC-like protein in Aeromonas hydrophila
Bacterial AraC is a transcription factor family that initiates transcription by recruiting RNA polymerase to the promoter. It also directly regulates various bacterial phenotypes. However, how this transcription factor regulates bacterial virulence and affects host immunity is still largely unknown....
