Plasmid-associated virulence of Salmonella enteritidis

Microbial Pathogenesis, 1988
Plasmid-associated virulence of Salmonella enteritidis was studied using plasmid-cured and plasmid-reintroduced strains. The plasmidless strain was unable to grow in the liver of mice after intravenous inoculation. Reintroduction of the plasmid pEX106 from the original S. enteritidis fully restored its capacity to grow in the mice.

Characterization of non-virulence plasmids with homology to the virulence plasmid of Salmonella dublin

Research in Microbiology, 1995
Six wild-type (wt) strains of Salmonella typhimurium, one wt strain of S. heidelberg and 12 wt strains of Escherichia coli were isolated based on both hybridization to a 6-kb HindIII fragment of the non-virulence coding part of the S. dublin serovar-specific virulence plasmid and the absence of hybridization to the virulence genes (spv genes) of the ...

Virulence plasmids

1994
Abstract The term plasmid was originally used by Lederberg (1) to describe all extra chromosomal hereditary determinants. Currently, the term is restricted to autonomously replicating extrachromosomal DNA. Their sizes range from 1 kb to more than 200 kb (2), and even larger plasmids were detected in Rhizobium (3). Although they replicate

Plasmid DNA of virulent Alcaligenes faecalis

American Journal of Veterinary Research, 1986
SUMMARY Alcaligenes faecalis strains originating from chickens and from epizootics of coryza in turkeys were screened for antibiotic susceptibility and for the presence of plasmid DNA. Seven of 35 strains contained plasmid DNA ranging in size from 10.5 to approximately 32 megadaltons.

The Large Virulence Plasmid of Shigella

1992
Invasion of human colonic epithelial cells constitutes one of the earliest steps in the pathogenesis of dysentery caused by Shigella species and enteroinvasive strains of Escherichia coli (EIEC). Following the invasion of target cells by virulent bacteria, their subsequent multiplication, intracellular movement, and intercellular spread result in a ...

Plasmid DNA in virulent and avirulent gonococci

Canadian Journal of Microbiology, 1975
The presence of covalently closed circular (CCC) DNA in virulent and avirulent colonial types of Neisseria gonorrhoeae strain 2686, and of type 3 colonies of strain F62 was investigated. CCC DNA was present in each, and the percentage of plasmid relative to total DNA was similar.
