A) Amplification plot of VIC labelled PCR products of VIM, NDM, and KPC (protocol 1), and B) OXA-48/CTX-M and VIM/IMP (protocol 2). Reactions were performed in the presence of the internal control PhHV. For clarity, a selection of strains is shown. OXA-48 positives with lower plots were also positive for CTX-M.
