Attaching and effacing (A/E) intestinal lesions are produced by enteropathogenic Escherichia coli (EPEC), enterohemorrhagic E. coli (EHEC), and RDEC-1, a pathogen of weanling rabbits. We recently identified a chromosomal locus (eae[E. coli A/E]) which is required for A/E activity in a wild-type EPEC strain. Sequences homologous to those of an eae gene probe were detected in EPEC, RDEC-1, and EH...

AIM We intended to find out the diversity of EPEC isolates among asymptomatic or diarrheal children in Iran using ribotyping. BACKGROUND Enteropathogenic Escherichia coli (EPEC) is responsible for gastroenteritis especially in young children. PATIENTS AND METHODS A total of 39 EPEC collected strains were serotyped and the presence of virulence genes as well as EAF plasmid among the strains ...

Enteropathogenic Escherichia coli (EPEC) was isolated from 11% of 148 Hmong children under 1 year old with diarrhea at a refugee camp in northern Thailand. Of 16 children with EPEC-associated diarrhea, 11 were infected with EPEC that adhered to HeLa cells in a diffuse pattern, 3 were infected with EPEC that adhered to HeLa cells in a localized adherence (LA) pattern, and 2 were infected with EP...

The hallmark of enterohemorrhagic Escherichia coli (EHEC) and enteropathogenic E. coli (EPEC) adhesion to cultured human host cells is intimate attachment and the formation of attaching and effacing (A/E) lesions. Recently, EHEC O157:H7 was shown to induce A/E lesions on human intestinal explants. Unlike EPEC, which colonized the small intestine, EHEC adhesion was restricted to follicle-associa...

The pathogenicity of enteropathogenic Escherichia coli (EPEC) is linked to the locus of enterocyte effacement, or LEE, encoding a type III secretion system (T3SS) that directly transfers bacterial effector proteins into eukaryotic cells. Atypical diffusely adhering EPEC (DA-EPEC) strains that harbor homologues of the LEE but lack the EPEC adherence factor plasmid have been increasingly associat...

As part of a study to determine the effects of water filtration on the incidence of community-acquired gastroenteritis in Melbourne, Australia, we examined fecal samples from patients with gastroenteritis and asymptomatic persons for diarrheagenic strains of Escherichia coli. Atypical strains of enteropathogenic E. coli (EPEC) were the most frequently identified pathogens of all bacterial, vira...

AIM The purpose of this study was to find the isolation rate of enteropathogenic Escherichia coli (EPEC) from lettuce samples collected in Tehran. BACKGROUND During the last decade, the prevalence of infectious diarrheal diseases due to consumption of contaminated food especially raw vegetable has been increasingly reported. Enteropathogenic Escherichia coli strains are an important group of ...

Here, we report the draft genome sequence of enteropathogenic Escherichia coli (EPEC) O146 strain isolated from a 1-year-old child with acute diarrhea in Delhi who recovered completely. The multidrug transporter (mdtABCD) gene, responsible for drug resistance, is present. The strain also contains the astA gene, an additional virulence determinant.
