1. Etest MBL strip (reprinted with permission from AB BIODISK, Solna, Sweden) and an Acinetobacter sp. expressing a VIM-2 MBL. The intersection of the ellipses at the strip is read from two halves, i.e., at the section with imipenem alone (IP) and imipenem plus EDTA (IPI).
Etest MBL strip (reprinted with permission from AB BIODISK, Solna, Sweden) and an Acinetobacter sp. expressing a VIM-2 MBL. The intersection of the ellipses at the strip is read from two halves, i.e., at the section with imipenem alone (IP) and imipenem plus EDTA (IPI). A reduction in the MIC of imipenem of ≥3 dilutions in the presence of EDTA is interpreted as a positive test.
