Complete Genome Sequence and Comparative Metabolic Profiling of the Prototypical Enteroaggregative Escherichia coli Strain 042
BACKGROUND Escherichia coli can experience a multifaceted life, in some cases acting as a commensal while in other cases causing intestinal and/or extraintestinal disease. Several studies suggest enteroaggregative E. coli are the predominant cause of E. coli-mediated diarrhea in the developed world and are second only to Campylobacter sp. as a cause of bacterial-mediated diarrhea. Furthermore, ...
متن کاملEvolution of Bacterial Global Modulators: Role of a Novel H-NS Paralogue in the Enteroaggregative Escherichia coli Strain 042
Bacterial genomes sometimes contain genes that code for homologues of global regulators, the function of which is unclear. In members of the family Enterobacteriaceae, cells express the global regulator H-NS and its paralogue StpA. In Escherichia coli, out of providing a molecular backup for H-NS, the role of StpA is poorly characterized. The enteroaggregative E. coli strain 042 carries, in add...
متن کاملThe hydrophobic surface protein layer of enteroaggregative Escherichia coli strains.
The surface of three strains of enteroaggregative Escherichia coli (EAggEC) and three strains of enteropathogenic E. coli (EPEC) were examined using the freeze-substitution technique of electron microscopy and as a result an electron dense surface layer was found only on EAggEC strains but not on EPEC strains. The analysis of the outer membrane proteins by polyacrylamide gel electrophoresis rev...
متن کاملEnteroaggregative Escherichia coli.
Enteroaggregative Escherichia coli (EAEC) are an increasingly important cause of diarrhoea. E. coli belonging to this category cause watery diarrhoea, which is often persistent and can be inflammatory. EAEC have been implicated in sporadic diarrhoea in children and adults, in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide. EAEC are ...
متن کاملThe Prevalence of Enteroaggregative Escherichia coli in cases of Diarrhea in Gorgan, IRAN
Abstract Background and objectives: Diarrhea is one of the main cases of morbidity and mortality among children in developing countries. Enteroaggregative Escherichia coli (EAggEC) is an emerging diarrheal pathogen that has been associated characteristically with persistent diarrhea among infants, particularly in the developing Counties. Therefore, we decided to study the prevalence of enteroag...
