| Erratum in the breakpoint table v 11.0 |
Erratum in the Staphylococcus spp tab (fluroquinolone section): Footnote C should read: Isolates categorised as susceptible to norfloxacin can be reported susceptible (S) to moxifloxacin and "susceptible increased exposure" (I) to ciprofloxacin and levofloxacin. Isolates non-wild type to norfloxacin should be tested for susceptibility to individual agents. |

| New software for the display of MIC andzone diameter distributions |
The EUCAST MIC and zone diameter distribution 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) has been re-programmed and re-launched 24 November, 2020. Each graph is shown in two versions where one is constructed by adding all approved distributions and the other by adding weighted distributions. The later is generated through converting numbers to per cent before adding individual distributions. This prevents large distributions from dominating or even "obliterating" smaller distributions and allows all distributions equal weight. During 2021 distributions are curated in accordance with EUCAST SOP10.1 and all values gradually reviewed. |
