CONTEXT Enteroaggregative Escherichia coli strains have been associated with persistent diarrhea in several developing countries. In vivo procedures with animal models, in vitro assays with cellular lines and in vitro organ culture with intestinal fragments have been utilized to study these bacteria and their pathogenicity. OBJECTIVE The present experimental research assessed the pathogenic i...

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 ...

Enteroaggregative E. coli (EAEC) is an established diarrhoeagenic pathotype. The association with virulence gene content and ability to cause disease has been studied but little is known about the population structure of EAEC and how this pathotype evolved. Analysis by Multi Locus Sequence Typing of 564 EAEC isolates from cases and controls in Bangladesh, Nigeria and the UK spanning the past 29...

background: diarrhea, caused by enteroaggregative escherichia coli (eaec), is an important cause of illness and death. numerous virulent factors have been described in eaec. however, their prevalence was highly variable among eaecs of distinct geographic locations. studies have shown that dispersin (antiaggregation protein, aap) is one of the important and abundant virulent factors in eaec. in ...

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...

We examined stool samples from travelers for secretory immunoglobulin A (sIgA) to enteroaggregative Escherichia coli (EAEC) during episodes of acute diarrhea. Ten paired samples from 10 patients with diarrhea caused by EAEC were examined for the presence of specific sIgA by dot blot and Western blot immunoassays. Five samples were positive by dot blotting, and two samples were positive by Weste...
