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 - ).
Our results show that the ECOFFs defined by EUCAST for tetracycline and ciprofloxacin can be used for C. jejuni and C. coli. The same ECOFF can be used for erythromycin for the three species.

Wild-type upper limits (WT-UL) were determined following EUCAST principles for epidemiologic cutoff value (ECOFF) setting. 2015-06-18 2010-12-01 2015-06-01 2015-06-01 ECOFF, epidemiological cut-off value (mg/L) as defined by EUCAST. The EUCAST-AFST considers that fluconazole is appropriate therapy for candidaemia in neutropenic and non-neutropenic patients, chronic disseminated candidosis, disseminated cutaneous neonatal candidosis, 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 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.

Wild-type upper limits (WT-UL) were determined following EUCAST principles for epidemiologic cutoff value (ECOFF) setting. The variability in the results obtained with these methods hampers setting epidemiological cut-off (ECOFF) values and clinical breakpoints according to EUCAST guidelines. Methods for susceptibility testing and determination of the minimal inhibitory concentrations (MICs) need to be standardized for MTBC isolates for old and new agents. CLSI and EUCAST susceptibility breakpoints for voriconazole and Candida albicans differ by one dilution (≤0.125 and ≤0.06 mg/liter, respectively) whereas the epidemiological cutoff values for EUCAST (ECOFF) and CLSI (ECV) are the same (0.03 mg/liter).
Antimicrobial susceptibility testing of Campylobacter isolates is of great importance for treatment options especially in systemic diseases. 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. ♦EUCAST recommends to ignore the colonies and only read when there is a haze ♦Some investigators have taken an approach where scattered colonies were taken into account only if they were in a … ECOFF values are not the same as clinical breakpoint concentrations.
