Plasmid encoded enterotoxin (Pet) gene in enteroaggregative Escherichia coli isolated from sporadic diarrhea cases.
(2). The aggregative adherence of EAggEC was due to the presence of aggregative adherence fimbriae (AAF), AAF/ 1 and AAF/lI, whose expression lS positively controlled by the aggR gene (2)・ This aggR gene is present in many EAggECs, but some aggR-positive E. coli isolates have no AAFs (3,4). EAggEC was found to produce EAggEC heat-stable enterotoxin (EASTl encoded by astA, molecular weight 4.1 k...
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 کاملEnteroaggregative escherichia coli virulence factors in traveler's diarrhea strains.
Enteroaggregative Escherichia coli (EAEC) is associated with diarrhea in Spanish travelers to developing countries. In this study, the polymerase chain reaction was used to test EAEC isolates for genes encoding putative virulence factors, including EAEC adhesins, the plasmid-encoded toxin (Pet), a heat-stable enterotoxin (EAST), and Shigella enterotoxins 1 and 2 (ShET1 and ShET2). Findings incl...
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 ...
متن کاملGenetic detection of diarrheagenic Escherichia coli isolated from children with sporadic diarrhea.
Escherichia coli strains are among the major bacterial causes of diarrheal illness. At least 5 categories of diarrheagenic E. coli (DEC) are recognized, namely enterotoxigenic E. coli (ETEC), enteropathogenic E. coli (EPEC), enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAEC), and enterohemorrhagic E. coli (EHEC). Due to the need for costly and labor-intensive diagnostic procedures,...
