Relationship of virulence-associated autoagglutination to hemagglutinin production in Yersinia enterocolitica and Yersinia enterocolitica-like bacteria.
A total of 339 Yersinia strains were tested for virulence-associated autoagglutination and hemagglutinin (HA) production. Autoagglutination was frequent among human clinical isolates belonging to Y. enterocolitica serogroups O:3, O:8, and O:9 and among porcine isolates of serogroups O:3 and O:9. Positive autoagglutination results were also observed in serogroups O:1 and O:2, associated with out...
متن کاملDetection of Yersinia Pestis by Comparison of Virulence Plasmid (pyv/pcd)-associated Phenotypes in Yersinia Species*
Consumption of meat contaminated with Yersinia pestis can cause oropharyngeal plague in humans. Existing microbiological media designed for selective detection of Y. pestis in food are not satisfactory for that purpose. Expression of genetic determinants in Yersinia species including low calcium response (Lcr), colony size, crystal violet (CV) binding, Congo red (CR) uptake, autoagglutination (...
متن کاملThe virulence plasmid of Yersinia, an antihost genome.
The 70-kb virulence plasmid enables Yersinia spp. (Yersinia pestis, Y. pseudotuberculosis, and Y. enterocolitica) to survive and multiply in the lymphoid tissues of their host. It encodes the Yop virulon, an integrated system allowing extracellular bacteria to disarm the cells involved in the immune response, to disrupt their communications, or even to induce their apoptosis by the injection of...
متن کاملTemperature-inducible outer membrane protein of Yersinia pseudotuberculosis and Yersinia enterocolitica is associated with the virulence plasmid.
A strain of Yersinia pseudotuberculosis which harbors a 63-kilobase plasmid was found to cause a lethal infection in Swiss albino mice. The rate of infection paralleled the ability of the pathogenic organism to attach to a monolayer of HeLa cells. One novel outer membrane protein (protein 1) with a molecular weight of 140,000 was found to be associated with the possession of the 63-kilobase pla...
متن کاملStructural 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...
