Quality control MIC ranges used for telavancin with application of a revised CLSI reference broth microdilution method

The telavancin broth microdilution susceptibility testing method was revised, which provides MIC results lower than those obtained by the previous method. This study was performed to reestablish the quality control ranges for telavancin when tested against the strains (updated MIC range) Staphylococcus aureus ATCC 29213 (0.03 to 0.12 μg/ml), Enterococcus faecalis ATCC 29212 (0.03 to 0.12 μg/ml), and Streptococcus pneumoniae ATCC 49619 (0.004 to 0.015 μg/ml).
