Results of screening of carbapenemase-producing members of the family Enterobacteriaceae by interpretation criteriaa
| Antibiotic | % PPVb | % NPVc |
|---|---|---|
| Imipenem | 93.5 (29/31) | 50.7 (73/144) |
| Meropenem | 96.3 (26/27) | 50.0 (74/148) |
| Ceftazidime | 74.8 (89/119) | 80.4 (45/56) |
| Moxalactam | 93.7 (74/79) | 72.9 (70/96) |
| Moxalactam (≥16 mg/liter) | 90.4 (85/94) | 81.5 (66/81) |
| Ceftazidimed | 67.0 (61/91) | 95.7 (45/47) |
a
The interpretation criteria used were those in reference 21, except for moxalactam (≥16 mg/liter).
b
The values in parentheses are the number of carbapenem producers/number of resistant isolates.
c
The values in parentheses are the number of non-carbapenem producers/number of susceptible and nonsusceptible isolates.
d
IMP-type enzyme producers, n = 63.
