PURPOSE: The mechanisms underlying colistin heteroresistance in Acinetobacter baumannii are not fully understood. Here, we investigated the role of efflux in colistin-heteroresistant populations of a multidrug-resistant (MDR) A. baumannii clinical isolate. METHODOLOGY: Three colistin-resistant A. baumannii strain variants isolated from the same clinical sample were studied for the presence of heteroresistance to colistin by drug […]
