Abstract: Escherichia coli strains that cause nonbloody diarrhea in infants are known to present three distinct patterns of adherence to epithelial cells, namely, localized (LA), diffuse (DA), and aggregative (AA) adherence. Strains with LA (typical EnteropathogenicEscherichia coli [EPEC]) are well recognized as a cause of secretory diarrhea, but the role of strains with DA (DAEC) is controversial, and strains with AA (EAEC) have been more frequently related to persistent diarrhea whereas its relationship with acute dia… Show more

“…Studies concerning aEPEC virulence have aimed at identifying diarrhea-associated virulence genes or phenotypic characteristics. Scaletsky et al (1999) showed that aEPEC expressing LAL were significantly associated with diarrhea (Table 1). In a study of infectious intestinal disease in England, the characterization of aEPEC strains by serotyping, intimin subtyping and antimicrobial resistance typing showed no significant differences among aEPEC strains isolated from patients vs. healthy controls (Jenkins et al, 2006).…”

“…1b) (Rodrigues et al, 1996). This pattern is defined only in assays using prolonged incubation periods (6-h assays) and is the most frequent pattern among aEPEC strains (Pelayo et al, 1999;Scaletsky et al, 1999;Vieira et al, 2001;Dulguer et al, 2003;Gomes et al, 2004;Abe et al, 2007). LAL probably corresponds to the poor LA pattern as described previously by Knutton et al (1991).…”

“…The first DNA probe, named daaC, was generated by Stapleton et al (413) and was a 300-bp PstI fragment of plasmid pSSS1 (daa operon), coding for part of an accessory protein of F1845 adhesin expressed by the diarrheagenic Afa/Dr DAEC C1845 strain (43). This DNA probe has been used in a large majority of the epidemiological studies of the association of Afa/Dr DAEC with diarrhea and urinary tract infections (1,5,68,112,127,130,131,141,143,152,208,209,256,257,293,329,344,364,366,367,400). Another constructed DNA probe, named drb (130), was a 260-bp PstI fragment of plasmid pIL14 (afa-1 operon) coding for the AfaE-I adhesin expressed by the uropathogenic Afa/Dr DAEC KS52 strain (243).…”

“…aEPEC strains have been found in association with endemic diarrhea in children and diarrhea outbreaks in adults in developing and industrialized countries (Viljanen et al, 1990;Hedberg et al, 1997;Scaletsky et al, 1999;Afset et al, 2004;Robins-Browne et al, 2004;Cohen et al, 2005;Bueris et al, 2007;Moreno et al, 2008;Estrada-Garcia et al, 2009). Apparently, this pathotype emerged recently and it is among the leading causes of childhood diarrhea in many countries (Afset et al, 2004;Robins-Browne et al, 2004;Cohen et al, 2005;Franzolin et al, 2005;Bueris et al, 2007;Estrada-Garcia et al, 2009).…”
