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

Staphylococcus aureus temperate bacteriophage: carriage and horizontal gene transfer is lineage associated. [PDF]

, 2012
Staphylococcus aureus is a major cause of human and animal infections. Bacteriophage are a class of mobile genetic element (MGE) that carry virulence genes and disseminate them horizontally, including Panton-Valentine leukocidin (PVL), the immune evasion

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.
