Project description:Escherichia coli is the predominant agent causing both different disease categories of complicated urinary tract infections (UTIs) and asymptomatic bacteriuria (ASB) cases. This study employed microarray analysis to identify the differences and similarities in the expression of genes among the Uropathogenic Escherichia coli (UPEC) and two ASB E.coli isolates that represent different end continuums of its disease severities.
Project description:The primary goals of this study are to: determine how intracellular infection of urothelial cells with uropathogenic Escherichia coli influences urothelial cell metabolism, and determine the influence of cytochrome bd on the urothelial cell response to infection
Project description:The objective of the study was to reveal the spatio-temporal distribution of gene expression and the evolutionary patterns of uropathogenic Escherichia coli during biofilm development. We provided a list of unannotated genes that are candidate genes associated with biofilm formation using genomic phylostratigraphy approach.
Project description:Transcriptional profiles of uropathogenic Escherichia coli CFT073 exposed to cranberry-derived proanthocyanidins (PACs) were determined. Our results indicate that bacteria grown on media supplemented with PACs were iron-deprived. To our knowledge, this is the first time that PACs have been shown to induce a state of iron-limitation in this bacterium.
Project description:Escherichia coli release Extracellular Vesicles (EVs) which carry diverse molecular cargo. Pathogenic E.coli EVs contain virulence factors which assist during infection in the host in different mechanisms.The RNA cargo of E.coli EVs has not been assessed in their effect in the host. We used microarray data to asses and compare the global response of bladder cells to EV-RNA from pathogenic E.coli (Uropathogenic UPEC 536) and non-pathogenic E. coli (probiotic Nissle 1917)
