CTX-M-15 has become the most prevalent extended-spectrum beta-lactamase amongst Escherichia coli in many countries during the past decade. Its dominance partly reflects the dissemination of an E. coli O25b:H4 ST131 clone that commonly produces this enzyme. We describe rapid real-time polymerase chain reaction (PCR) assays able to detect E. coli belonging to the ST131 clone and to identify bla(CTX-M-15)-like.
