Several methods are used worldwide for antibiotic susceptibility testing (AST) for the Mycobacterium tuberculosis complex (MTBC). The variability in the results obtained with these methods hampers setting epidemiological cut-off (ECOFF) values and clinical breakpoints according to EUCAST guidelines.

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. Methods for susceptibility testing and determination of the minimal inhibitory concentrations (MICs) need to be standardized for MTBC isolates for old and new agents. 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 Committee to harmonize antimicrobial breakpoints, organized by ESCMID, ECDC and European national breakpoint committees.

The good correlation between doxycycline MIC ECOFF (2 mg/L) and tetracycline zone diameter ECOFF (23 mm) shown in our study (see Supplementary material, Fig. S27) enabled EUCAST to recommend disc diffusion using a tetracycline 30-μg disc as a screening test to predict doxycycline susceptibility in B. pseudomallei Översättnings-API; Om MyMemory; Logga in EUCAST guidelines for detection of resistance mechanisms and specific resistances of clinical and/or epidemiological importance EUCAST, December 2012 Christian G. Giske (Sweden, EUCAST Steering Committee and EARS-Net Coordination Group; chairman), Luis Martinez-Martinez (Spain and EUCAST Steering Committee), 2017-11-01 · ECOFF/wild-type definitions Isolates were categorized as wild-type (wt) or non-wild-type (non-wt) adopting the EUCAST ECOFFs. These have been defined for A. fumigatus , Aspergillus flavus , Aspergillus niger , Aspergillus terreus and Aspergillus nidulans (voriconazole and isavuconazole) [16] , [17] and for Candida albicans , Candida glabrata , Candida krusei , Candida parapsilosis and Candida 2018-03-26 · And so the isolates with MICs above the ECOFF are assumed to be resistant. However that may not actually be the case- higher dosing may enable higher drug levels and clinical effectiveness. Here we have a nice separation of wildtype (green) and non -WT (red) isolates with an ECOFF (at the upper limit of the WT distribution) that separates the two well.
