Results in parentheses indicate percentage. MIC determined by agar dilution method. HLG=High-level gentamycin (500 µg/ml), HLS=High-level streptomycin (2000 µg/ml). Range of glycopeptide MIC: 0.125 to 256 µg/ml. Breakpoints for vancomycin: [S]: ≥4 µg/ml; [I]: 8-16 µg/ml; [R]: 8-16µg/ml. Breakpoints for teicoplanin: [S]: ≥8 µg/ml; [I]: 16 µg/ml; [R]: 16 µg/ml.
