Rapid identification of ST131 Escherichia coli by a novel multiplex real-time allelic discrimination assay

Escherichia coli sequence type 131 is increasingly described in severe hospital infections. We developed a rapid real-time allelic discrimination assay for the rapid identification of E. coli ST131 isolates. This rapid assay represents an affordable alternative to sequence-based strategies before completing characterization of potentially highly virulent isolates of E. coli.
