Project description:While in transit within and between hosts, uropathogenic E. coli (UPEC) encounter multiple stresses, including substantial levels of nitric oxide and reactive nitrogen intermediates. Strains of UPEC become conditioned to high concentrations of acidified sodium nitrite (ASN), a model system used to generate nitrosative stress. We used microarrays to define the expression profile of UPEC that have been conditioned for growth in ASN.
Project description:The purpose of this study is to determine whether the presence of pathogenic Escherichia coli in colon is associated with psychiatric disorders.
Project description:We previously determined that loss of respiratory quinol oxidase cytochrome bd disrupts biofilm formation in uropathogenic Escherichia coli (UPEC). In this study, we extracted and interrogated the outer membrane and extracellular matrix of colony biofilms formed by UPEC isolate UTI89 and an isogenic mutant lacking cytochrome bd (∆cydAB).
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 expression levels of uropathogenic E. coli (UPEC) UTI89 cells in YESCA broth with and without 4% dimehtyl sulfoxide (DMSO) and 2% ethanol (EtOH) were studied.
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)
