AB - An eight-laboratory study addressed the urgent need for quality control (QC) ranges for susceptibility determination when testing colistin (polymyxin E) and polymyxin B, two polycationic peptide antimicrobial agents, against multidrug-resistant gram-negative bacilli. For Escherichia coli ATCC 25922l, the QC ranges were as follows: for colistin, 0.25 to 1 µg/ml (11 to 17 mm), and for polymyxin B, 0.25 to 2 µg/ml (13 to 19 mm). For Pseudomonas aeruginosa ATCC 27853, the QC ranges were as follows: for colistin, 0.25 to 2 µg/ml (11 to 17 mm), and for polymyxin B, 0.25 to 2 µg/ml (14 to 18 mm). More than 97% of all reported QC results were within these proposed ranges.
