[Susceptibility testing of yeasts against fluconazole: proposal for a standardized agar diffusion method with 25 microgram fluconazole paper discs]

This paper gives a proposal for a standardised agar diffusion susceptibility testing method with 25 micrograms fluconazole discs. The methodology compiles the results of several years of work to develop a reliable and reproducible routine-method for the microbiology laboratory. In this proposal, in addition, the critics and experiences of a collaborative study for susceptibility testing of fluconazole with 21 laboratories from Germany and Austria are included.
