Gac two-component system in Pseudomonas syringae pv. tabaci is required for virulence but not for hypersensitive reaction [PDF]

open access: yes, 2008
Pseudomonas syringae pv. tabaci 6605 causes wildfire disease on host tobacco plants. To investigate the regulatory mechanism of the expression of virulence, Gac two-Component system-defective mutants, Delta gacA and Delta gacS, and a double mutant, Delta

FNR Regulates the Expression of Important Virulence Factors Contributing to the Pathogenicity of Avian Pathogenic Escherichia coli

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Avian pathogenic Escherichia coli (APEC) is the etiologic agent of colibacillosis, an important cause of morbidity and mortality in poultry. Though, many virulence factors associated with APEC pathogenicity are known, their regulation remains unclear ...

TroA of Streptococcus suis is required for manganese acquisition and full virulence [PDF]

open access: yes, 2011
Streptococcus suis causes infections in pigs and occasionally in humans resulting in 23 manifestations as meningitis, sepsis, arthritis and septic shock. For survival within the 24 host, S. suis requires numerous nutrients including trace metals.

Selection of virulence-associated determinants of Streptococcus suis serotype 2 by in vivo complementation [PDF]

open access: yes, 2001
Within Streptococcus suis serotype 2, pathogenic, weakly pathogenic, and nonpathogenic strains can be found. We introduced a genomic library of a pathogenic strain into a weakly pathogenic strain.

Optimal Response to Quorum-Sensing Signals Varies in Different Host Environments with Different Pathogen Group Size

open access: yesmBio, 2020
The persistence of genetic variation in master regulators of gene expression, such as quorum-sensing systems, is hard to explain. Here, we investigated two alternative hypotheses for the prevalence of polymorphic quorum sensing in Gram-positive bacteria,

Predicting the virulence of MRSA from its genome sequence [PDF]

open access: yes, 2014
This work is supported by the EC-FP7 program no. 245500 and the BBSRCMicrobial virulence is a complex and often multifactorial phenotype, intricately linked to a pathogen's evolutionary trajectory.

The palmitoyl-CoA ligase Fum16 is part of a Fusarium verticillioides fumonisin subcluster involved in self-protection

open access: yesmBio
Fusarium verticillioides produces the mycotoxin fumonisin B1 (FB1), which disrupts sphingolipid biosynthesis by inhibiting ceramide synthase and affects the health of plants, animals, and humans. The means by which F. verticillioides protects itself from

The genome of a pathogenic rhodococcus : cooptive virulence underpinned by key gene acquisitions [PDF]

open access: yes, 2010
We report the genome of the facultative intracellular parasite Rhodococcus equi, the only animal pathogen within the biotechnologically important actinobacterial genus Rhodococcus. The 5.0-Mb R.

Evolution of Salmonella-Host Cell Interactions through a Dynamic Bacterial Genome

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Salmonella Typhimurium has a broad arsenal of genes that are tightly regulated and coordinated to facilitate adaptation to the various host environments it colonizes. The genome of Salmonella Typhimurium has undergone multiple gene acquisition events and
