Comparison of vancomycin MICs determined by tube macrodilution on low and standard bacterial inoculaa
Vancomycin MIC (μg/ml) | No. (%) of isolates with vancomycin MIC (μg/ml) determined in: |
|||
---|---|---|---|---|
Low-inoculum group (5 × 104 CFU/ml) |
Standard-inoculum group (106 CFU/ml) |
|||
24 h | 48 h | 24 h | 48 h | |
1 | 31 (55) | 11 (20) | 7 (12) | 0 (0) |

MICs were determined for 56 MRSA blood isolates.
