EUCAST technical note on anidulafungin.

The European Committee on Antimicrobial Susceptibility Testing-Subcommittee on Antifungal Susceptibility Testing has determined breakpoints for anidulafungin for Candida spp. This Technical Note is based on the EUCAST anidulafungin rationale document (available at: http://www.eucast.org). Species-specific breakpoints for C. albicans are S ≤0.03 mg/L and R >0.03 mg/L and for C. glabrata, C. tropicalis and C. krusei S ≤0.06 mg/L and R >0.06 mg/L. C. parapsilosis was not regarded a good target for anidulafungin. There are insufficient data to set breakpoints for other species. The breakpoints are based upon pharmacokinetic data, epidemiological cut-off values and clinical experience. Breakpoints will be reviewed regularly.
