Project description:Enteropathogenic Yersinia enterocolitica and Yersinia pseudotuberculosis share many traits in terms of infections they cause, but their epidemiology and ecology seem to differ in many ways. Pigs are the only known reservoir for Y. enterocolitica 4/O:3 strains while Y. pseudotuberculosis strains have been isolated from variety of sources including fresh vegetables and wild animals. A comparative genomic hybridization (CGH) analysis with a DNA microarray based on three Yersinia enterocolitica and four Yersinia pseudotuberculosis genomes was conducted to shed light on genomic differences between the enteropathogenic Yersinia. In total 99 strains isolated from various sources were hybridized and analyzed.

Project description:The enteric pathogen Yersinia enterocolitica is a the most common gram-negative zoonotic pathogen that causes a variety of gut-associated diseases named yersiniosis ranging from enteritis, watery diarrhea, mesenteric lymphadenitis to post infectious extraintestinal sequelae such as reactive arthritis human yersiniosis. The species Y. enterocolitica comprises a diverse group of about 70 serotypes of which only 11 are harmful to humans. Among the pathogenic strains are the highly mouse-virulent 1B/O:8 strains (YeO:8). This bioserotype, in particular YeO:8 strain 8081v has been used to study the pathogenesis of Y. enterocolitica using mouse infection models. However, by far the most frequent cause of human yersiniosis in Europe and Japan (>90%) is Y. enterocolitica bioserotype O:3 (YeO:3), which is also frequently found in pigs and pork products. In this study a comparative RNA-seq-based transcriptomic approach was used to identify serotype/isolate-specific differences in the transcriptome of the isolates YeO:8 8081v and YeO:3 Y1 under infection-relevant conditions. This strategy allowed the generation of the first in-depth single-nucleotide resolution transcriptome of Y. enterocolitica, revealed major differences in the temperature- and growth phase-dependent expression profiles, and led to the discovery of changes that modulate transcripts levels of important virulence-relevant traits. Additionally a comprehensive map of transcriptional start sites for Y. enterocolitica was generated using cDNA libraries based on samples enriched for primary transcripts.

Project description:Pathogenic bacteria Yersinia enterocolitica injects virulence plasmid-encoded effectors through the type three secretion system into macrophages to modulate gene expression. Here we analyzed the effect on gene expression in primary human macrophages of Y. enterocolitica strains lacking effector YopP (1.5 h infection) or effectors YopP and YopM (1.5 h or 6 h infection) simultaneously using RNA-seq. This is part of a larger sequencing experiment for which other samples can be found in EMBL-EBI (www.ebi.ac.uk/arrayexpress) under accession number E-MTAB-10473 and European Nucleotide Archive (ENA) at http://www.ebi.ac.uk/ena/data/view/PRJEB10086.

Project description:Pathogenic bacteria Yersinia enterocolitica injects virulence plasmid-encoded effectors through the type three secretion system into macrophages to modulate gene expression. At this point it is not known whether epigenetic modifications play a role in Yersinia regulation of gene expression. To answer this question primary human macrophages were infected with mock, WAC (virulence plasmid-cured strain) or WA314 (wild type) and samples were subjected to ChIP-seq for H3K4me3, H3K4me1, H3K27ac and H3K27me3. The effect of effector proteins YopM and YopP on histone modifications in macrophages was analyzed using a wild type strain lacking either YopM or YopP and subsequent ChIP-seq analysis.

Project description:Orogastral infection of mice with Yersinia enterocolitical leads to HIF-1 alpha activation.To elucidate whether this HIF-1 alpha activation also results in a HIF-1 dependent gene programming, the transcriptomes from Peyers Patches of uninfected and Yersinia enterocolitica infected mice were analyzed by means of of microarray analyses using Affymetrix GeneChip probe arrays (MG-U74Av2). In total, 288 genes were differentially regulated three day after infection in PP compared with the expression of uninfected control mice. Of these 288 genes, 217 were found to be differentially upregulated and from these, 14 genes ( 6.5% of all upregulated genes) are well described to be regulated via HIF-1. These data indicate that orogatral infection with Y. enterocolitica results in HIF-1 dependent gene programmning Keywords: Time course
