EUCAST Disk Diffusion Test Methodology

The EUCAST disk diffusion test is based on MH media and disks of a good quality. It is calibrated to EUCAST clinical breakpoints using broth microdilution for MIC determination. Updates are published regularly. 

 

The EUCAST Development Laboratory has systematically investigated the quality of MH-powders, antibiotic disks and of pre-poured MH plates for disk diffusion. The publications from these investigations are available from the EUCAST website (antibiotic disk qualityMH powder quality, the quality of pre-poured MH plates).
