MIC and zone distributions and ECOFFs

MIC distributions - curated distributions

MIC distributions and zone diameter distributions are added to the distribution database when available. The consequence of this is that ECOFF values may be added, TECOFFs may reach ECOFF status, and on occasion ECOFFs revised.  

During 2019 - 2020 all MIC distributions are reviewed in accordance with criteria in SOP 10.1. Some ECOFFs and TECOFFs may be added, lost or changed as a result of this.


Currently the following list of agents are under review (2019 - 20):

  • ciprofloxacin
  • nalidixic acid
  • colistin
  • daptomycin
