Detecting imipenem resistance in Acinetobacter baumannii by automated systems (BD Phoenix Microscan WalkAway Vitek 2); high error rates with Microscan WalkAway

摘要

BackgroundIncreasing reports of carbapenem resistant Acinetobacter baumannii infections are of serious concern. Reliable susceptibility testing results remains a critical issue for the clinical outcome. Automated systems are increasingly used for species identification and susceptibility testing. This study was organized to evaluate the accuracies of three widely used automated susceptibility testing methods for testing the imipenem susceptibilities of A. baumannii isolates, by comparing to the validated test methods.
