Part Description

LP207314-8   Escherichia coli O157 rfbE gene
The rfbE gene in Escherichia coli (E coli) O157 encodes perosamine synthase and is the first O157 Shiga toxin-producing E coli (STEC) rfb locus to be cloned and sequenced. [PMID: 8890241] The rfbE gene is used in PCR assays to distinguish serotype O157 from non-O157 STEC in a clinical specimens. [PMID: 16480968] Although rfbE is specific for serotype O157, it does not distinguish between O157:H7 and O157:non-H7 strains. E. coli O157:H7 (enterohemorrhagic E. coli or EHEC) is a well-known food-borne pathogen. E. coli O157:non-H7 strains are not classified as EHEC and their clinical significance is less clear. Such non-H7 strains have been isolated from asymptomatic patients, patients with diarrhea, as well as food and environmental sources. [PMID: 21876740] Source: Regenstrief LOINC
