Evaluation Report of the Colistin Broth Disk Elution Method with Acinetobacter baumannii Isolates from a Low-Resource Setting

Abstract

The relatively cumbersome broth microdilution (BMD) method for routine colistin susceptibility testing has not been adopted, especially in low-resource settings, often leading to the underreporting of colistin susceptibility and the promotion of the empirical use of colistin. In this regard, the much-preferred colistin broth disk elution (CBDE) method has not yet been approved for A. baumannii .
