TranscriptomicsComparative Genomic Hybridization of E. coli and Shigella species to determine the relatedness of isolates from Neobladders
Using comparative genomic hybridization we examined the genome content of 30 isolates of E. coli and Shigella to determine the relative location of E. coli isolates from the human neobladder Isolates were included in the study that represent the prototype strains of multiple pathovars. No replicate...

TranscriptomicsGlobal transcriptomics of enterotoxigenic E. coli strain E24377A
ETEC is an important human pathogen. Although the mechanism of diarrhea is known in ETEC, the regulatory networks are less understood. This study was conducted to understand the global expression of ETEC isolate E24377A under different growth and environmental conditions. ETEC E24377A was grown in...

TranscriptomicsThe role of qseE, qseF and qseG in the regulation of EHEC virulence
Escherichia coli 8624 and the isogenic mutants in qseE, qseF and qseG are compared to determine the role that each of the genes play in regulation of the transcriptome. These results are verified by qRT-PCR and reveal the important role of this three-component signaling system. Escherichia coli 862...

TranscriptomicsQseA regulation of virulence factors in EHEC
Enterohemorrhagic E. coli (EHEC) colonizes the large intestine and causes attaching and effacing lesions (AE). Most of the genes involved in the formation of AE lesions are encoded within a chromosomal pathogenicity island termed the Locus of Enterocyte Effacement (LEE). The LysR-like transcriptiona...

TranscriptomicsHfq virulence regulation in enterohemorhagic Escherichia coli O157:H7 strain 86-24
Escherichia coli O157:H7 is a food-borne pathogen that causes bloody diarrhea and hemolytic uremic syndrome. Hfq is an sRNA chaperone protein that is involved in post-transcriptional regulation of virulence genes in pathogenic bacteria. In EHEC strain EDL933, Hfq acts a negative regulator of the loc...

TranscriptomicsIdentification of entertoxigenic Escherichia coli genes transcriptionally altered with the interaction of host cells
Genes identified in ETEC E24377A after interaction with host cells (Caco-2) after time points of 30 min, 60 min and 120 min. Both the adherent and non-adherent cells were profiled as well as E24377a grown only in tissue culture media. Each time and sample has at least duplicate samples

TranscriptomicsEscherichia coli global gene expression in urine from women with urinary tract infection
Examination of E. coli transcripts present in bacteria in urine samples from 8 patients attending a urology clinic with symptoms of cystitis, as compared to transcripts present in the same E. coli strains during mid-exponential growth in filter-sterilized human urine in vitro. A 48 array study using...
