Between October 2007 and March 2008, 153 wild boars shot in the Canton of Geneva in Switzerland were sampled. Fifty-one percent of the animals were males and 49% were females. The age of most (81%) animals varied between 6months and 2years. Prevalence of enteropathogenic Yersinia in tonsils and faeces was studied using culture and PCR methods and in tissue fluid of tonsils using an ELISA system...

During the study, we isolated 575 strains of enterobacteria from various animal species belonging to genus Escherichia, Shigella, Salmonella, Klebsiella, Proteus, Providencia, Hafnia, Morganella, Enterobacter, Citrobacter, Serratia, Erwinia, Kluyvera, Yersinia. In farm animals, amount transient pathogenic Salmonella enteritidis and Yersinia enterocolitica did not exceed 0.22-0.12%. Among wild p...

The cation content in commercial media obtained from two manufacturers showed considerable variation. Even different batches of the same make were found to be inconsistent in the content of metal ions. With cultures of Cytophaga sp. and Yersinia pseudotuberculosis in base media, growth stimulation was dependent on additions of certain commercial media. It could be demonstrated that this stimula...

We report the first draft genome sequences of five Yersinia pseudotuberculosis isolates of sequence type (ST) 19 and of a variant from one of the five isolates. The total length of assemblies ranged from 4,226,485 bp to 4,274,148 bp, including between 3,808 and 3,843 predicted coding sequences.

background and objectives: loop-mediated isothermal amplification is a novel nucleic acid amplification assay providing as a simple diagnostic tool for rapid identification of microbial diseases in developing countries. in this study, a lamp assay was established for yersinia enterocolitica , a leading cause of acute enterocolitis in young children. materials and methods: lamp assay was establi...

We report the first draft genome sequences of two Yersinia pseudotuberculosis sequence type 43 (ST43) (O:1b) strains, B-7194 and B-7195, isolated in Russia. The total lengths of the assemblies are 4,427,121 bp and 4,608,472 bp, and 3,819 and 4,018 coding sequences, respectively, were predicted within the genomes.

Yersinia enterocolitica is well equipped for siderophore piracy, encompassing the utilization of siderophores such as ferrioxamine, ferrichrome, and ferrienterochelin. In this study, we report on the molecular and functional characterization of the Yersinia fep-fes gene cluster orthologous to the Escherichia coli ferrienterochelin transport genes (fepA, fepDGC, and fepB) and the esterase gene f...

Pathogenic Yersinia spp. use a panel of virulence proteins that antagonize signal transduction processes in infected cells to undermine host defense mechanisms. One of these proteins, Yersinia enterocolitica outer protein P (YopP), down-regulates the NF-kappaB and MAPK signaling pathways, which suppresses the proinflammatory host immune response. In this study, we explored the mechanism by whic...

Abstract: Y. enterocolitica and Y. pseudotuberculosis are important food borne pathogens. However, the presence of competitive microbiota makes the isolation of Y. enterocolitica and Y. pseudotuberculosis from naturally contaminated food...
