Investigations into the problems with susceptibility testing of species with breakpoints for cefiderocol have been performed by EUCAST and others. The warning has been updated 16 August, 2022. Work is continued and further updates may be expected.
Get to know moreThe next breakpoint table (valid from 1 Jan, 2023) is now available for comments and questions. Please address comments to erika.matuschek[at]eucast.org or gunnar.kahlmeter[at]eucast.org no later than 19 December, 2022.
Get to know moreStriving to keep EUCAST users informed of upcoming changes, this short document describes the planned major changes to the breakpoint tables v 11.0 (2021). The table itself will be published for consultation on or about 5 December, 2020.
Get to know moreEUCAST AFST recently proposed new breakpoints for amphotericin B, three echinocandins and flucytosine against Candida auris . A public consultation was held 2025-03-06 - 2025-04-17. Now (2025-06-17) the EUCAST AFST has responded to comments .
Get to know moreThis is a general invitation to attend EUCAST zoom updates on the 11th of November (8 AM, 1 PM and 4 PM). Current EUCAST projects will be described, the next breakpoint table summarised and there will be opportunities to discuss.
Get to know moreRecently we made breakpoints available (on the website) for RAST incubation beyond the standard 4, 6 and 8h for when reading at those incubation times is not prectical. Now the rationale for this is published in the Journal of Antimicrobial Chemotherapy .
Get to know moreWe are frequently asked questions regarding (1) EUCAST Warning No. 7 : is this warning specifically directed at benzylpenicillin gradient tests (Etest TM , bioMérieux, and MTS TM , Liofilchem) when used for Streptococcus pneumoniae or does it apply to other bacteria, (2) is it still valid or have we…
Get to know moreWith changes in the breakpoint table v 12.0 and the adding of disk diffusion criteria for anaerobic bacterial and for Vibrio spp, the calibration filesshowing the relationship between MIC and inhibition zone diameters need updating. These are now available (Vibrio spp to follow).
Get to know moreThe Staphylococcus spp. Expert Rules document was updated 1 Febr, 2023. The detection of benzylpenicillin resistance in S. lugdunensis is based on the breakpoints only - the assessment of inhibition zome edge has been removed fro S. lugdunensis but remains for S. aureus .
