Vancomycin MICs for Methicillin-Resistant Staphylococcus aureus Isolates Differ Based upon the Susceptibility Test Method Used

Abstract
Recent studies have questioned treatment of serious methicillin-resistant Staphylococcus aureus (MRSA) infections with vancomycin because of treatment failures, despite vancomycin MICs in the susceptible category (MIC ≤ 2 μg/ml) ([2][1], [3][2], [5][3], [6][4], [7][5]). Some of these studies have
