The virulence plasmids of Salmonella.

International microbiology : the official journal of the Spanish Society for Microbiology, 2000
Certain Salmonella serovars belonging to subspecies I carry a large, low-copy-number plasmid that contains virulence genes. Virulence plasmids are required to trigger systemic disease; their involvement in the enteric stage of the infection is unclear.

Salmonella typhimurium Bacteremia: Association with the Virulence Plasmid

Journal of Infectious Diseases, 1992
Virulence plasmids, which are found in a small number of Salmonella serotypes, greatly enhance the extraintestinal growth of salmonellae and lower the LD50 by 2-5 logs in experimental murine infections. To determine if virulence plasmids are important in the pathogenesis of Salmonella bacteremia in humans, blood and fecal isolates of Salmonella ...

Genome-Scale Analysis of Virulence Plasmids: the Contribution of Plasmid-Borne Virulence Genes to Enterobacterial Pathogenesis

2014
This chapter discusses the genome-scale analysis of virulence plasmids: the contribution of plasmid-borne virulence genes to enterobacterial pathogenesis. The spectrum of diseases caused by Escherichia coli and other enteric bacteria is due to the acquisition of a variety of specific virulence genes harbored on plasmids, on bacteriophages, or within ...

[Virulence plasmids of Shigella bacteria].

Molekuliarnaia genetika, mikrobiologiia i virusologiia, 1991
The contemporary data on the genetical control of invasion process in dysentery causative agent coded by the virulence plasmids of the bacteria are presented. The examples of plasmid genes expression regulated by the genes-regulators located on the chromosome are presented. The mechanism for virulence genes regulation is discussed.

Plasmid borne virulence of Enterobacter hafniae.

Acta microbiologica Polonica, 1978
The strain classified as Enterobacter hafniae has been isolated in a severe epidemy of porcine diarrhoea. Its pathogenicity has been found to be cotransmissible with resistance to oxytetracycline when the strain was grown in a mixed culture with some nonpathogenic E. hafniae strains as well as with Escherichia coli. Toxinogenity seems to be responsible

The Virulence Plasmids of Shigella flexneri

2009
Shigella species and enteroinvasive Escherichia coli possess a large virulence plasmid that carries the genes necessary for invasion and colonization of the epithelial cell layer of the human gut resulting in dysentery. The plasmid is a hybrid molecule with a complex evolutionary history.

[The "side-effects" of plasmids (R-plasmids and virulence)].

Molekuliarnaia genetika, mikrobiologiia i virusologiia, 1987
Many plasmids affect the host cells. Their effects cannot be explained only by the expression of the well-known genes coding for antibioticresistance, bacteriocinogeny and hemolysis or the analogous genes (side-effects). The side effects are not characteristic of all plasmids operating under similar conditions.
