Evaluation of Three Automated Systems for Susceptibility Testing of Enterobacteria Containing qnrB, qnrS, and/or aac(6′)-Ib-cr

摘要

The accuracy of the MicroScan WalkAway, BD Phoenix, and Vitek-2 systems for susceptibility testing of quinolones and aminoglycosides against 68 enterobacteria containing qnrB, qnrS, and/or aac(6 ′)-Ib-cr was evaluated using reference microdilution. Overall, one very major error (0.09%), 6 major errors (0.52%), and 45 minor errors (3.89%) were noted.
