2015-06-18 Species: Candida albicans (Method: MIC ) MIC distributions include collated data from multiple sources, geographical areas and time periods and can never be used to infer rates of resistance 2013-06-13 In summary, EUCAST has developed tools to use PK/PD and MCS to set breakpoints by considering the relationship between PK/PD index and MIC that includes the variability in both exposure and MIC. The representation of the results of MCS in graphical or tabular plots of PK/PD index versus MIC allows an interpretation of this relationship that is otherwise not readily possible. 2020-09-21 Corresponding MIC values are shown through the colouring of bars. The colours correspond to EUCAST ceftazidime MIC breakpoints for B. pseudomallei (S ≤ 0.001 mg/L, R > 8 mg/L): I, yellow and R, orange/red; S - Susceptible, standard dosing regimen, I - Susceptible, increased exposure, R - Resistant.

For the most updated version of the EUCAST clinical breakpoints for bacteria and fungi, please visit the EUCAST Clinical Breakpoints page . MIC-bestämning. För bakterier där EUCAST har fastställda brytpunkter anges både MIC-värdet och S/I/R kategorin i svaret. För arter som saknar brytpunkter anges endast MIC-värdet. 1. MIC-bestämning med mikrobuljongspädningsmetod (Broth Microdilution, BMD, Sensititre, ThermoFisher) The EUCAST reference MIC method is not intended primarily for use in clinical microbiology routine. Within EUCAST, it will be the only method used for defining ECOFFs and clinical breakpoints for MTBC, but other AST methods may be used with EUCAST clinical breakpoints as long as they are calibrated according to the EUCAST AMST recommendations ( www.eucast.org ).

The EUCAST recommendations for MIC determination for non-fastidious organisms are in complete agreement with the recommendations from the International Standards Organisation (ISO). 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. 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). EUCAST develops a disk diffusion susceptibility test method calibrated to EUCAST MIC breakpoints.

ATB™ and mini API® have also been updated with new strips that include the EUCAST breakpoints. Etest® strips provide on-scale MIC results and since they provide an extensive MIC range, they completely cover the EUCAST breakpoints. In addition, bioMérieux has validated Etest products with Mueller Hinton 2 agar (MHF).

Breakpoints for antifungals; MIC distributions and ECOFFs The role of pharmacokinetics/pharmacodynamics in setting clinical MIC breakpoints: the EUCAST approach. Clinical breakpoints are used in clinical microbiology laboratories to categorize microorganisms as clinically susceptible (S), intermediate (I) or resistant (R) dependent on the quantitative antimicrobial susceptibility as indicated by the MIC Antimicrobial susceptibility testing of Mycobacterium tuberculosis complex isolates - the EUCAST broth microdilution reference method for MIC determination. The EUCAST reference method for MTBC was endorsed by EUCAST after public consultation and will from now on be used to define EUCAST ECOFFs and clinical breakpoints. The European Committee on Antimicrobial Susceptibility Testing - EUCAST. 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 - ).
