EUCAST has proposed formal principles for ECOFF setting (available at www.eucast.org). A number of specific acceptance criteria for the individual MIC distributions are proposed, one of which is that the modes of the individual wild-type distributions must be equal to or within one 2-fold dilution of the most common mode observed in the collection of at least five valid MIC distributions prior

A EUCAST Subcommittee is currently reviewing the rules for inclusionandexclusionofdata setsin aggregatedMICdistributions and the process by which ECOFF values are deﬁned. Contributors of MIC data are not informed about whetheror not their contributions are accepted. There are currently more than 29

Using also the EUCAST ECOFF, a significant increase in the proportion of isolates above this ECOFF was observed: from 3.7% in 2017 to 7.6% in 2018 (p<0.0002). In 2018, 24 countries 2020-07-09 The EUCAST epidemiological cut-off (ECOFF) values for meropenem and ertapenem identiﬁed all carbapenemase producers, whereas the imipenem ECOFF failed in ﬁve strains. All carbapenemase producers were detected with EUCAST disk diffusion breakpoints for ertapenem and meropenem, and four strains were susceptible to imipenem.

The variability in the results obtained with these methods hampers setting epidemiological cut-off (ECOFF) values and clinical breakpoints according to EUCAST guidelines.

The ECOFF finder program is now available from the EUCAST website The ECOFF finder program for the assessment of epidemiological cutoff values (ECOFFs) is now available from the EUCAST website. <- Back to: EUCAST News Committee to harmonize antimicrobial breakpoints, organized by ESCMID, ECDC and European national breakpoint committees. Subcommittees on antifungal susceptibility testing, susceptibility testing of anaerobes and interpretative reading and expert rules in susceptibility testing. This distribution obviously includes both wild type and drug resistant isolates.

EUCAST is a standing committee jointly organized by ESCMID, ECDC and European national breakpoint committees. EUCAST was formed in 1997. It has been chaired by Ian Phillips (1997 - 2001), Gunnar Kahlmeter (2001 - 2012), Rafael Canton 2012 - 2016) and Christian Giske (2016 - ).

CLSI • Both methods are based on Mueller-Hinton agar, but there are differences in: – Disk potency • Several disk contents are lower in EUCAST – Medium • EUCAST: MH. and . MH-F • CLSI: MH, HTM and Sheep blood. – Incubation time • EUCAST: 16-20 h . for all organisms • CLSI: 16-18 or 20-24 h EUCAST – recent documents • Expert Rules v 2.0 – CMI 2012 • EUCAST and PK/PD – CMI 2012 • EUCAST AFST - breakpoints and RDs for antifungal agents published (Candidae and Aspergillus). • Guidance on Stenotrophomons maltophilia 2012 • Guidance on direct AST 2012 • Guidance on systemic breakpoints for oral cephalosporins This study demonstrates that ECOFF-based analysis of AST data of only four aminoglycosides provides accurate information on the resistance mechanisms in E. coli.

The C. jejuni and C. coli ECOFFs for ciprofloxacin however cannot be applied to C. fetus. Epidemiologic Cutoff Values Epidemiologic cutoff values, abbreviated ECV (CLSI) or ECOFF (Eucast) , are measures of a drug MIC distribution that separate bacterial populations into those representative of a wild type population, and those with acquired or mutational resistance to the drug. EUCAST is a standing committee jointly organized by ESCMID, ECDC and European national breakpoint committees. EUCAST was formed in 1997. It has been chaired by Ian Phillips (1997 - 2001), Gunnar Kahlmeter (2001 - 2012), Rafael Canton 2012 - 2016) and Christian Giske (2016 - ). Before using the EUCAST breakpoint tables - make sure you read this. There are changes in the breakpoint tables every year.

• The ECOFF – The ECOFF distinguishes between organisms without and with phenotypically expressed resistance mechanisms for a species and a drug in a defined test system. – Within a species, it is the highest MIC of organisms lacking phenotypically expressed resistance. – Organisms without resistance mechanisms are not by default EUCAST ECOFF: 23 mm .

The EUCAST software, originally created in 2003, for displaying distributions of MIC-values (generated with methods calibrated to broth microdilution or agar dilution) and inhibition zone diameters (generated with EUCAST disk diffusion methodology) was re-programmed during 2020 and re-launched on 24 November, 2020.

Before using the EUCAST breakpoint tables - make sure you read this. There are changes in the breakpoint tables every year. Some may be difficult to understand or accept without having followed the development of and consultations on the changing definitions of the susceptibility categories, especially the change from the old "intermediate" (I) to the new "Susceptible, increased exposure" (I). ECOFF values are not the same as clinical breakpoint concentrations. More information: MIC and zone diameter distributions and ECOFFs (EUCAST, 2020) Tags: The mic.eucast.org website is the EUCAST software for displaying distributions of MIC-values (generated with broth microdilution according to the ISO-standard or with methods calibrated to broth microdilution or when appropriate agar dilution) and inhibition zone diameters (generated only with EUCAST disk diffusion methodology with disks and media from several manufacturers). Subsequently, olorofim MICs were compared to itraconazole, voriconazole, posaconazole, and amphotericin B MICs for 298 clinical mold isolates (2016 to 2017).
