Brief report

Evaluation of daptomycin susceptibility testing by Etest and the effect of different batches of media

Peter C. Fuchs,*, Arthur L. Barry and Steven D. Brown

The Clinical Microbiology Institute, 9725 SW Commerce Circle, Suite A-1, Wilsonville, OR 97070, USA

One hundred and ninety-five Gram-positive bacteria representing 17 species were tested for susceptibility to daptomycin by broth microdilution and Etest methods. The geometric mean daptomycin MIC was 0.46 mg/L by broth microdilution tests and 0.73 mg/L by Etest. The concentration of calcium in 12 different batches of agar varied from 4 to 36 mg/L. Daptomycin Etest MICs varied inversely with the calcium concentration. Etest daptomycin MICs for quality control strains were within proposed quality control range on media with >20 mg/L of calcium. Monitoring the calcium levels of agar media by testing appropriate quality control strains is important for daptomycin Etests.
