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: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

Project description:RNA-sequencing was preformed from RNA isolated from bacteria infected with the bacteriophage. In order to reveal the phage-host interactions between φR1-37 and Yersinia enterocolitica throughout the phage infection cycle, both the transcriptomes were scrutinized during all the stages of infection.

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.

These data indicate that orogatral infection with Y. enterocolitica results in HIF-1 dependent gene programmning Experiment Overall Design: Per group five C57BL/6 mice were infected orogastrally with 500 Million Yersinia enterocolitica. 1 and 3 days after infection, Peyers Patches were removed and total RNA was prepared. In parallel, RNA was isolated from uninfected mice. The generation of fragmented cRNA was performed following the manufacturers instructions and used for hybridization onto GeneChip arrays MG-U74Avs2. Analysis of microarray data was performed using the Affymetrix Microarray Suite 5.0, Affymetrix Mining Tool 3.0. A median signal log2 ratio (SLR) grater than 1.5 or less than -1.5 was considered a significant change.
