Disk diffusion of anaerobic bacteria

A laboratory trial designed to investigate the robustness of the EUCAST disk diffusion test for rapidly growing anaerobic bacteria (Bacteroides spp, Prevotella spp, Fusobacterium necrophorum, Clostridium perfringens and Cutibacterium acnes) is underway. Twenty laboratories around the world have signed up and today trial isolates are expected to have reached all. The EUCAST Development Laboratory (EDL) planned the trial together with the EUCAST Steering Committtee and colleagues in the EUCAST Subcommittee on Antimicrobial Susceptibility Testing of Anaerobic bacteria. The EDL prepared and distributed the strains and has arranged for the distribution of media and disks to participants. Results are expected before the end of May.
