چکیده

An F-lac plasmid from Escherichia coli was transferred to virulent Yersinia pestis, resulting in the repression of virulence. The Y. pestis F-lac clones retained all of the known virulence traits but were avirulent and calcium independent. Every lac segregant derived from the F-lac clones was fully virulent and calcium dependent.

Calcium-regulated type III secretion of Yop proteins by an Escherichia coli hha mutant carrying a Yersinia pestis pCD1 virulence plasmid.

A series of four large deletions that removed a total of ca. 36 kb of DNA from the ca. 70-kb Yersinia pestis pCD1 virulence plasmid were constructed using lambda Red-mediated recombination. Escherichia coli hha deletion mutants carrying the virulence plasmid with the deletions expressed a functional calcium-regulated type III secretion system. The E. coli hha/pCD1 system should facilitate molec...

Characterization of common virulence plasmids in Yersinia species and their role in the expression of outer membrane proteins.

The virulence plasmids pYV019, pYV8081, and pIB1 from Yersinia pestis, Yersinia enterocolitica, and Yersinia pseudotuberculosis, respectively, were characterized by restriction endonuclease analysis. The three plasmids exhibited a region of common DNA previously shown to encode determinants which confer Ca2+ dependence. The plasmids from Y. pestis and Y. pseudotuberculosis were similar througho...

Structural organization of the pFra virulence-associated plasmid of rhamnose-positive Yersinia pestis.

The 137,036-bp plasmid pG8786 from rhamnose-positive Yersinia pestis G8786 isolated from the high mountainous Caucasian plague focus in Georgia is an enlarged form of the pFra virulence-associated plasmid containing genes for synthesis of the antigen fraction 1 and phospholipase D. In addition to the completely conserved genes of the pFra backbone, pG8786 contains two large regions consisting o...

Intrinsic plasmids influence MicF-mediated translational repression of ompF in Yersinia pestis

Yersinia pestis, which is the causative agent of plague, has acquired exceptional pathogenicity potential during its evolution from Y. pseudotuberculosis. Two laterally acquired plasmids, namely, pMT1 and pPCP1, are specific to Y. pestis and are critical for pathogenesis and flea transmission. Small regulatory RNAs (sRNAs) commonly function as regulators of gene expression in bacteria. MicF, is...

Simple and Rapid Detection of Yersinia Pestis and Francisella Tularensis using Multiplex-PCR

Background: Yersinia pestis and Francisella tularensis cause plague and tularemia, which are known as diseases of the newborn and elderly, respectively. Immunological and culture-based detection methods of these bacteria are time-consuming, costly, complicated and require advanced equipment. We aimed to design and synthesize a gene structure as positive control for molecular detection of these ...
