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:The purpose of our study was to fill this knowledge gap and to characterize the epithelial cell response to Yersinia enterocolitica infection by label-free proteomic quantification.
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: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.
