Evaluation of Etest MBL for Detection of bla[subscript IMP-1] and bla[subscript VIM-2] Allele-Positive Clinical Isolates of Pseudomonas spp. and Acinetobacter spp

The Etest MBL (AB BIODISK, Solna, Sweden) correctly differentiated all 57 isolates of Acinetobacter spp. and Pseudomonas aeruginosa with the bla[subscript IMP-1] allele and 135 of 137 (98.5%) Acinetobacter spp. and Pseudomonas spp. isolates with the bla[subscript VIM-2] allele. The Etest MBL was reliable for detecting the IMP-1- and VIM-2-producing Pseudomonas and Acinetobacter isolates.
