The so called enteropathogenic Escherichia coli (EPEC) O serogroups include typical and atypical EPEC, enterohaemorrragic E. coli, enterotoxigenic E. coli, and enteroaggregative E. coli. The aim of this article is to review the composition of each O serogroup and the major serotypes, clones, and additional virulence characteristics of each of these diarrheagenic categories. Their adherence patt...

Escherichia coli isolates (n = 300) collected from six sites in subtropical Brisbane, Australia, prior to and after storm events were tested for the presence of 11 virulence genes (VGs) specific to diarrheagenic pathotypes. The presence of eaeA, stx(1), stx(2), and ehxA genes specific for the enterohemorrhagic E. coli (EHEC) pathotype was detected in 56%, 6%, 10%, and 13% of isolates, respectiv...

background and objectives: diarrheagenic escherichia coli (dec) is an emerging agent among pathogens that causes diarrhea. studies showed that diarrheagenic e. coli such as enterohaemorrhagic e. coli (ehec), enteroaggregative e. coli (eaec), enteropathogenic e. coli (epec), enteroinvasive e. coli (eiec), enterotoxigenic e. coli (etec), diffusely adhering e. coli (daec) and shiga toxin producing...

We identified different diarrheagenic (DEC) Escherichia coli pathotypes isolated from 1,207 children with and without acute endemic diarrhea in Salvador, Bahia, Brazil collected as part of a case-control study. Since the identification of DEC cannot be based on only biochemical and culture criteria, we used a multiplex polymerase chain reaction developed by combining five specific primer pairs ...

Although part of the normal gut flora, Escherichia coli strains are also important intestinal pathogens. Diarrheagenic E. coli (DEC) cause a wide variety of gastrointestinal diseases, particularly among children in developing countries, resulting in significant morbidity and mortality (Moyo, 2007; Khairun, 2007; Brandal, 2007; Nguyen, 2005; Rajendran, 2010; Franzolin, 2005). The DEC are differe...
