Extensive genomic diversity and selective conservation of virulence determinants in enterohemorrhagic Escherichia coli strains of O157 and non O157 serotypes [PDF]

, 2007
Background: Enterohemorrhagic Escherichia coli (EHEC) O157 causes severe food-borne illness in humans. The chromosome of O157 consists of 4.1 Mb backbone sequences shared by benign E.

Characterization of Pyrenophora teres isolates and mapping of virulence genes [PDF]

, 2021
Pyrenophora teres is the causative agent of net blotch of barley and one of the most economically important fungal pathogens affecting the Australian barley industry. The estimated yield losses due to net blotch exceed $300 million annually.

Low distribution of genes encoding virulence factors in Shigella flexneri serotypes 1b clinical isolates from eastern Chinese populations

Gut Pathogens, 2017
Background The ability of Shigella to invade, colonize, and eventually kill host cells is influenced by many virulence factors. However, there is no analysis of related genes in Jiangsu Province of China so far.

Whole Genome Sequence Analysis of Brucella melitensis Phylogeny and Virulence Factors

Microbiology Research, 2021
Brucellosis has a wide range of clinical severity in humans that remains poorly understood. Whole genome sequencing (WGS) analysis may be able to detect variation in virulence genes. We used Brucella melitensis sequences in the NCBI Sequence Read Archive

Hybrid Resistance and Virulence Plasmids in “High-Risk” Clones of Klebsiella pneumoniae, Including Those Carrying bla_NDM-5

Microorganisms, 2019
Virulence plasmids are associated with hypervirulent types of Klebsiella pneumoniae, which generally do not carry antibiotic resistance genes. In contrast, nosocomial isolates are often associated with resistance, but rarely with virulence plasmids. Here,

The KdpD/KdpE two-component system : integrating K+ homeostasis and virulence [PDF]

, 2013
The two-component system (TCS) KdpD/KdpE, extensively studied for its regulatory role in potassium (K+) transport, has more recently been identified as an adaptive regulator involved in the virulence and intracellular survival of pathogenic bacteria ...

Genomic and ecological attributes of marine bacteriophages encoding bacterial virulence genes

BMC Genomics, 2020
Background Bacteriophages encode genes that modify bacterial functions during infection. The acquisition of phage-encoded virulence genes is a major mechanism for the rise of bacterial pathogens.
