title: Rapid detection of Escherichia coli O157:H7 with multiplex real-time PCR assays.
abstract: A SYBR Green LightCycler PCR assay using a single primer pair allowed simultaneous detection of stx1 and/or stx2 of Escherichia coli O157:H7. A distinct sequence of the Shiga-like toxin genes was amplified to yield products of 227 and/or 224 bp, respectively. The two products were distinguished by melting point curve analysis.
