Comparison of rCDM, mCIM, and sCIM for selected strains.
| Strain (n) | Type of carbapenemase | rCDM zone diameter (mm) | sCIM zone diameter (mm) | mCIM zone diameter (mm) |
|---|---|---|---|---|
| Enterobacteriaceae (200) | KPC-2, IMP-4, IMP-2, VIM-1, NDM-1, OXA-48 | 6 | 6 | 6 |
| P. aeruginosa (35) | VIM-1, VIM-2, VIM-4, KPC-2, IMP-4 | 6 | 6 | 6–12 |
| P. aeruginosa (2) | VIM-4 | 15 | 6 | 6 |
| P. aeruginosa (1) | VIM-4 | 23 | 21* | 22 |
rCDM, rapid carbapenemase detection method; sCIM, simplified carbapenem inactivation method, mCIM, modified carbapenem inactivation method.
