Identification and Characterization of a Novel Genomic Island Integrated at <i>selC</i> in Locus of Enterocyte Effacement-Negative, Shiga Toxin-Producing <i>Escherichia coli</i>

Abstract excerpt

The selC tRNA gene is a common site for the insertion of pathogenicity islands in a variety of bacterial enteric pathogens. We demonstrate here that Escherichia coli that produces Shiga toxin 2d and does not harbor the locus of enterocyte effacement (LEE) contains, instead, a novel genomic island. In one representative strain (E. coli O91:H(-) strain 4797/97), this island is 33,014 bp long and, like LEE in E....
