Enteroaggregative Escherichia Coli (EAEC) in South of Iran
Introduction: The aim of the present study was to investigate the presence and the frequency of EAEC as etiologic agent of diarrhea in Shiraz. Enteroaggregative E. coli (EAEC) is increasingly recognized as a cause of often persistent diarrhoea in children and adults in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide. Materials and...
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...
متن کاملStructural relation of the antigenic polysaccharides of Escherichia coli O40, Shigella dysenteriae type 9, and E. coli K47.
O-polysaccharides were isolated from the lipopolysaccharides of Escherichia coli O40 and Shigella dysenteriae type 9 and studied by chemical analyses along with (1)H and (13)C NMR spectroscopy. The following new structure of the O-polysaccharide of E. coli O40 was established: -->2)-beta-D-Galp-(1-->4)-beta-D-Manp-(1-->4)-alpha-D-Galp-(1-->3)-beta-D-GlcpNAc-(1--> TheO-polysaccharide structure o...
متن کاملEnteroaggregative Escherichia coli: epidemiology, virulence and detection.
Enteroaggregative Escherichia coli (EAEC) is a subgroup of diarrhoeagenic E. coli (DEC) that during the past decade has received increasing attention as a cause of watery diarrhoea, which is often persistent. EAEC have been isolated from children and adults worldwide. As well as sporadic cases, outbreaks of EAEC-caused diarrhoea have been described. The definition of EAEC is the ability of the ...
