Which MIC determination and disk diffusion methods are represented?
The MIC distributions represent MIC values determined with methods described by ISO, EUCAST, BSAC (UK), CA-SFM (France), CRG (The Netherlands), DIN (Germany), NWGA (Norway), SRGA (Sweden) and CLSI (USA). Commercial MIC-determination methods standardized to any of the recognised methods are also included. The zone diameter distributions are based on inhibition zones generated by the EUCAST disk diffusion method only. Has data obtained with a specific method been excluded? For MIC data no specific method has been excluded. Contributions are screened by the EUCAST Steering Committee and less than 10% have been excluded from the aggregated distributions. However, all data are held in the database and are accessible to the Steering Committee. The most common reason for exclusion has been that the MIC ranges were truncated (not full-range) so that a significant proportion of MICs were outside the tested range (especially when at the low-end of the distribution).
