EUCAST is considering removing breakpoints for piperacillin without tazobactam and/or ticarcillin without clavulanic acid but only if these agents are no longer used. If you in your country are still using either or both of these agents without an inhibitor, please inform the EUCAST Scientific…

Get to know moreEUCAST will during 2023, based on the work of theEMERGE AST Working Group , strive to publish clinical breakpoints and disk diffusion correlates for Brucella melitensis and Bacillus anthracis. Through the joint effort of the group and EUCAST, MIC and zone diameter distributions are now available .…
Get to know moreThe correlation between MIC and inhibition zone diameters in disk diffusion is excellent when utilizing species specific breakpoints for anaerobic species and species groups, in the same way EUCAST has dealt with facultative aerobic bacteria over the last 25 years. In this presentation the EUCAST…
Get to know moreThere is a mistake in the EUCAST breakpoint table v 11.0 where, in the Staphylococcus spp tab, the fluroquinolone section, the footnote C should read:Isolates categorised as susceptible to norfloxacin can be reported susceptible (S) to moxifloxacin and "susceptible increased exposure" (I) to…
Get to know moreMIC distributions and ECOFFs ECOFFs can be used to detect isolates with resistance mechanisms and thus for surveillance of resistance development. For many or most species and agents, clinical breakpoints and ECOFFs will coincide but for some species and agents, isolates with low-level resistance…
Get to know moreProposed change of breakpoints for aminopenicillins in enterococci (consultation period 7 May - 14 June, 2024). Public consultation is part of the EUCAST decision process. The consultation period is 4 - 12 weeks, and the dates of the beginning and end of the period is clearly stated. Comments not…

Get to know moreThe EUCAST general consultation on Corynebacterium diphtheriae and C. ulcerans is open for comments 9 July - 11 September, 2022. Together with specialists in Paris and Munich, 200 isolates of each species were investigated with broth microdilution MIC determination and disk diffusion as a backdrop…
Get to know moreEUCAST has evaluated (August 2022) commercially available tests and all have problems with accuracy, reproducibility, bias and/or for some, with skipped wells. For this reason, it is difficult to resolve the susceptibility interpretation of isolates in the ATU (area of technical uncertainty) in…
