Project description:Despite the characterization of many aetiologic genetic changes. The specific causative factors in the development of sporadic colorectal cancer remain unclear. This study was performed to detect the possible role of Enteropathogenic Escherichia coli (EPEC) in developing colorectal carcinoma.

Project description:The method DFI-seq was developed to enable identification of differentially expressed genes in uropathogenic E. coli strain UTI89 during growth in human urine and in bladder epithelial cells. By utilising this new method, the aim was to identify novel virulence genes in UTI89. DFI-seq is a combination of differential fluorescence induction (DFI) with next-generation sequencing. DFI-seq was compared to DFI by analysing gene expression of UPEC in human urine and thereby confirming that DFI-seq gives a better overview of gene expression. DFI-seq was hereafter used to look at gene expression in UTI89 while infecting bladder epithelial cells. We demonstrate the usefulness of DFI-seq for identification of genes required for optimal growth of UPEC in human urine, as well as potential virulence genes upregulated during infection of bladder epithelial cells. DFI-seq holds potential for the study of bacterial gene expression in live-animal infection systems.

Project description:Background: Based on 32 Escherichia coli and Shigella genome sequences, we have developed an E. coli pan-genome microarray. Publicly available genomes were annotated in a consistent manor to define all currently known genes potentially present in the species. The chip design was evaluated by hybridization of DNA from two sequenced E. coli strains, K-12 MG1655 (a commensal) and O157:H7 EDL933 (an enterotoxigenic E. coli). A dual channel and single channel analysis approach was compared for the comparative genomic hybridization experiments. Moreover, the microarray was used to characterize four unsequenced probiotic E. coli strains, currently marketed for beneficial effects on the human gut flora. Results: Based on the genomes included in this study, we were able to group together 2,041 genes that were present in all 32 genomes. Furthermore, we predict that the size of the E. coli core genome will approach ~1,560 essential genes, considerably less than previous estimates. Although any individual E. coli genome contains between 4,000 and 5,000 genes, we identified more than twice as many (11,872) distinct gene groups in the total gene pool (“pan-genome”) examined for microarray design. Benchmarking of the design based on sequenced control strain samples demonstrated a high sensitivity and relatively low false positive rate. Moreover, the array was highly sufficient to investigate the gene content of apathogenic isolates, despite the strong bias towards pathogenic E. coli strains that have been sequenced so far. Our analysis of four probiotic E. coli strains demonstrate that they share a gene pool very similar to the E. coli K-12 strains but also show significant similarity with enteropathogenic strains. Nonetheless, virulence genes were largely absent. Strain-specific genes found in probiotic E. coli but absent in E. coli K12 were most frequently phage-related genes, transposases and other genes related to mobile DNA, and metabolic enzymes or factors that may offer colonization fitness, which together with their asymptomatic nature may explain their nature. Conclusion: This high-density microarray provides an excellent tool for characterizing either DNA content or gene expression from unknown E. coli strains. Keywords: Comparative genomic hybridizations

Project description:The pathogenesis of endometritis in dairy cows is related to pathogenic microorganisms, local inflammatory injury and uterine microecological disorders. Escherichia coli (E. coli) is the main causative pathogen of endometritis in dairy cows. Therefore, we investigated E. coli-induced endometritis mechanisms in dairy cows using bovine bone marrow-derived macrophages (BMDMs).E. coli infection was performed on BMDMs for 4 hours. BMDMs were pretreated with PGD2 inhibitors (H-PGDS Inhibitor 1, HQL-79) for 24 hours, followed by E. coli infection for 4 hours. Samples were collected and evaluated.
