Abstract

Objective: Optimizing colistin susceptibility testing has difficulties because of its high molecular weight and high binding capacity to polystyrene which is frequently used in antibiotic susceptibility testing. We aimed to compare the results of isolates, which were detected as colistin-resistant in the automated system, obtained by using broth microdilution (BMD) method which is the gold standard, with gradient diffusion method (GDM).
