Antimicrobial susceptibility testing of Clostridium difficile using EUCAST epidemiological cut-off values and disk diffusion correlates.

Clinical Microbiology and Infection, 05/04/2012

With proposed zone diameter breakpoints for metronidazole, vancomycin, and moxifloxacin of WT ≥ 23 mm, WT ≥19, and WT ≥ 20 mm respectively, authors found no very major errors and only major errors below 2%.In conclusion, we suggest that disk diffusion is an option for antimicrobial susceptibility testing of C. difficile.
