title: Antibiotic-resistant cell-detaching Escherichia coli strains from Nigerian children.
abstract: The properties of 23 cell-detaching Escherichia coli strains that were isolated from stool specimens in Nigeria are described. Common properties of the strains included the presence of genes encoding alpha-hemolysin (100%), pyelonephritis-associated pili (100%), and cytotoxic necrotizing factor 1 (70%) as well as lactose negativity (70%) and multiple antibiotic resistance (74%). Antibiotic resistance was shown in most cases to be transferable and associated with the presence of class 1 integrons. Phenotypic properties and pulsed-field gel electrophoresis analysis demonstrated that the majority of the strains, particularly multiply resistant, lactose-negative O4:H40 strains, were closely related. Multiply-resistant cell-detaching E. coli strains may represent an important reservoir for antibiotic resistance genes.
