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 -).

ESCMID Conference on Reviving Old Antibiotics The European Committee for Antimicrobial Susceptibility Testing (EUCAST) recently proposed epidemiological cut-offs (ECOFFs) for a limited number of antimicrobial compounds and for Campylobacter jejuni and Campylobacter coli only. Wild-type upper limits (WT-UL) were determined following EUCAST principles for epidemiologic cutoff value (ECOFF) setting. Olorofim median MICs comparing serial plates and ISO plates were identical (25/36 [69%]) or one dilution apart (11/36 [31%]). Interperson agreement for visual-MICs was 92% to 94%/100% for ≤1/≤2 dilutions, respectively. Antimicrobial susceptibility testing (AST) – EUCAST, CLSI, ECOFFs and Clinical Breakpoint determination Posted on August 21, 2015 by mdjkf EUCAST is increasingly becoming the dominant international standard for various reasons and its procedures and documentation, including breakpoint tables are available online for free. The European Committee for Antimicrobial Susceptibility Testing (EUCAST) recently proposed epidemiological cut-offs (ECOFFs) for a limited number of antimicrobial compounds and for Campylobacter jejuni and Campylobacter coli only. The variability in the results obtained with these methods hampers setting epidemiological cut-off (ECOFF) values and clinical breakpoints according to EUCAST guidelines.

All carbapenemase producers were detected with EUCAST disk diffusion breakpoints for ertapenem and meropenem, and four strains were susceptible to imipenem. Additionally, WT-ULs were determined statistically using 97.5% and 99% endpoints and the EUCAST ECOFFinder program, and the previously described derivatization method, which provides a single ECOFF. 10 A consensus WT-UL was chosen taking into account the eyeball and statistical endpoints and the fact that some MIC distributions were slightly truncated to the left and therefore resulted in ECOFF (mg/L) 0.016 0.032 0.064 0.125 0.25 0.5 1 2 4 8 16 32 64 128 256 512; The EUCAST-AFST considers that fluconazole is appropriate therapy for candidaemia in Since January 2019, the EUCAST clinical resistance breakpoint for azithromycin of MIC>0.5 mg/L has been replaced with an ECOFF of MIC>1 mg/L. 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 Infatti con EUCAST è stato introdotto il concetto di cut-off epidemiologico (ECOFF), la minima concentrazione di antibiotico in grado di inibire tutti i ceppi "selvaggi" ( Wild Type ) di una specie. Un germe è detto "selvaggio" (WT) se è esente da qualsiasi meccanismo di resistenza acquisita; al Affiliations 1 EUCAST Development Laboratory, Växjö, Sweden.

The ECOFFinder software estimates the MIC breakpoint that separates the population into wild type and non-wild type, with an ECV ≦ 0.0625 mg/L, much lower than the indicated EUCAST and CLSI breakpoints. Only about 47% of the isolates tested had cefepime MICs. ECOFF ECOFFs for the early detection of resistance development Gunnar Kahlmeter EUCAST, ESCMID . Clinical microbiology, Växjö, Sweden .

However, the ECOFF values determined using one or the other of the methods coincide to within one dilution step. 19 Furthermore, there are published and ongoing studies that show an excellent correlation between using EUCAST ECOFFs as available on the web site and WGS to distinguish organisms that harbour resistance mechanisms from those that do not, both in Enterobacteriaceae 22 and in

for all organisms • CLSI: 16-18 or 20-24 h 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. In 2002, EUCAST launched the concept of gathering large numbers of MIC values to present as aggregated MIC distributions for each species-agent combination and to determine epidemiological cut-off values (ECOFF) on. The distributions are for bacteria and fungi and for antimicrobial agents that are or have been used in human and veterinary medicine.
