The most studied pathotypes are Shiga toxin-producing <em>E.</em> <em>coli</em> (STEC), enterotoxigenic <em>E.</em> <em>coli</em> (ETEC), enteropathogenic <em>E.</em> <em>coli</em> (EPEC), enteroaggregative <em>E.</em> <em>coli</em> (EAEC), and enteroinvasive <em>E.</em> <em>coli</em> (EIEC). The objective of the study was to characterize the isolates of diarrheagenic <em>E.</em> <em>coli</em> from an outpatient pediatric population with diarrhea attended in two public hospitals from Buenos Aires, Argentina. Diarrheagenic <em>E.</em> <em>coli</em> pathotypes were investigated by amplifying characteristic virulence gene fragments: intimin (<em>eae</em>), heat-labile toxin (<em>lt</em>), heat-stable toxins (<em>stp</em>, <em>sth</em>), invasion plasmid antigen H (<em>ipaH</em>), transcriptional activator R (<em>aggR</em>) and Shiga toxins (<em>stx1</em>, <em>stx2</em>). Molecular subtyping of isolates was performed using PFGE (XbaI). Diarrheagenic <em>E.</em> <em>coli</em> was detected in 14% (84/601) of cases. The EAEC pathotype was prevalent, while ETEC, STEC, EPEC and EIEC were found in a lower proportion. EAEC isolates exhibited a high degree of genetic diversity.
