Presence and characterization of a mosaic genomic island which distinguishes sorbitol-fermenting enterohemorrhagic Escherichia coli O157:H- from E. coli O157:H7.

ABSTRACT: A mosaic genomic island comprising Shigella resistance locus (SRL) sequences flanked by segments of Escherichia coli O157:H7 strain EDL933 O islands 43, 81, and 82 was identified in sorbitol-fermenting (SF) enterohemorrhagic Escherichia coli (EHEC) O157:H(-) strain 493/89. This mosaic island is absent from strain EDL933. PCR targeting the SRL-related sequence is a useful tool to distinguish SF EHEC O157:H(-) from EHEC O157:H7.
