Abstract
We determined the incidence of enterovirulent E coli EVEC which can to cause gastrointestinal infections in strains isolated from patients with both of the major inflammatory bowel diseases IBD Crohn’s disease CD and ulcerative colitis UC and from patients with noninflammatory bowel diseases nonIBD Cell detachment E coli CDEC were detected in 14 of all strains A significant difference in the presence of CDEC was found between the groups of strains isolated from UC 241 nonIBD 119 and CD 47 Enteroaggregative E coli EAggEC were detected in 25 typical enteropathogenic strains EPEC in 13 and enterotoxigenic ones ETEC in 15 Enteroinvasive EIEC and shigatoxin producing E coli STEC were not detected Some strains showed a high invasion level in gentamicinprotection assay These strains could therefore belong to adherentinvasive E coli AIEC because they are free of genes encoding invasins ipaH ial and are equipped with fimA gene However complete characterization of these strains and their classification as AIEC will require further tests
