Co-conjugation of Virulence Plasmid and KPC Plasmid in a Clinical Klebsiella pneumoniae Strain [PDF]

Frontiers in Microbiology, 2021
Carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-HvKP) strains have been increasingly reported, and it is important to understand the evolutionary mechanisms of these highly pathogenic and resistant bacterial pathogens.

Plasmids andAeromonasvirulence [PDF]

FEMS Immunology & Medical Microbiology, 1997
Most putative virulence determinants of Aeromonas species are chromosomally encoded. However, several recent reports have indicated that some may be carried on or regulated by plasmids. Therefore, we examined the plasmid carriage rate of a total of 140 clinical and environmental Aeromonas isolates.

Genetic characterization and passage instability of a novel hybrid virulence plasmid in a ST23 hypervirulent Klebsiella pneumoniae [PDF]

Frontiers in Cellular and Infection Microbiology, 2022
Hypervirulent variants of Klebsiella pnuemoniae (hvKP), which causes life-threatening infections, is a global priority pathogen and frequently harbours virulence plasmids. The virulence plasmids have emerged as the predominant vehicles carrying the major

Genetic and Functional Characterization of a Conjugative KpVP-2-Type Virulence Plasmid From a Clinical Klebsiella pneumoniae Strain [PDF]

Frontiers in Microbiology, 2022
The main mechanism of virulence in Klebsiella pneumoniae is the acquisition of K. pneumoniae virulence plasmids (KpVPs), which include two dominant types, namely, KpVP-1 (carrying iuc1, iro1, rmpA, and rmpA2) and KpVP-2 (carrying iuc2, iro2, and rmpA ...

Plasmid-mediated virulence in Chlamydia

Frontiers in Cellular and Infection Microbiology, 2023
Chlamydia trachomatis infection of ocular conjunctiva can lead to blindness, while infection of the female genital tract can lead to chronic pelvic pain, ectopic pregnancy, and/or infertility.

A ParDE toxin–antitoxin system is responsible for the maintenance of the Yersinia virulence plasmid but not for type III secretion-associated growth inhibition [PDF]

Frontiers in Cellular and Infection Microbiology, 2023
Many Gram-negative pathogens utilize the type III secretion system (T3SS) to translocate virulence-promoting effector proteins into eukaryotic host cells.

Mobilization of the nonconjugative virulence plasmid from hypervirulent Klebsiella pneumoniae [PDF]

Genome Medicine, 2021
Background Klebsiella pneumoniae, as a global priority pathogen, is well known for its capability of acquiring mobile genetic elements that carry resistance and/or virulence genes.

Complete nucleotide sequences of virulence-resistance plasmids carried by emerging multidrug-resistant Salmonella enterica Serovar Typhimurium isolated from cattle in Hokkaido, Japan. [PDF]

PLoS ONE, 2013
In the present study, we have shown that virulence-resistance plasmids from emerging multidrug-resistant isolates of Salmonella enterica serovar Typhimurium were derived from a virulence-associated plasmid, essential for systematic invasiveness of S ...

Yersinia virulence: more than a plasmid [PDF]

FEMS Microbiology Letters, 2001
The genus Yersinia is composed of 11 species, three of which are pathogenic in humans. The three pathogens, Y. pestis, Y. enterocolitica, and Y. pseudotuberculosis, cause a broad spectrum of disease ranging from pneumonic plague to acute gastroenteritis.
