Methods: The results of 12 well-characterised multidrug-resistant strains tested by nine laboratories using local disk diffusion (DD) and automated AST (AUST) methods were compared with the reference broth microdilution method. Results: Overall categorical agreement ranged from 70% to 100% both for DD and AUST and was >90% for all but one strain for all antibiotics. Conclusion: Our multicentre AST study showed good reproducibility and the panel can be used as national resistant reference strains for routine AST validation. (C) 2022 The Author(s).
