N2 - To investigate the prevalence of attaching and effacing Escherichia coli, we examined 364 strains isolated from the feces of 9,684 patients with diarrhea at the Anjo Kosei Hospital in Japan for the presence of eaeA. Twenty-nine (8%) of the strains were eaeA positive. Of enteropathogenic E. coli (EPEC), 11 of the 87 (13%) strains were for the positive eaeA gene. The serotypes and the numbers of eaeA-positive strains among the strains tested were as follows: O26:H-(2/3), O55:H7 (4/4), O55:H-(2/ 2) and O128:H2(3/3). Two enterohemorrhagic E. coli (EHEC) strains (Verotoxin positive O157:H7) were also eaeA positive. Among 260 non-EPEC strains that were not categorized as diarrheagenic E. coli, 16 (6%) were eaeA positive. Those serotypes were as follows: O15:H2, O20:H6, O28:H28, O63:H6. O153:H7, O28:H6, O153:H19 and O157:H45. EPEC strains including O18:H7 and six other serotypes, enteroinvasive E. coli (EIEC), and enterotoxigenic E. coli (ETEC) were all eaeA negative.
