Summary of surveillance sample results, real-time PCR, and phenotypic screen isolates
| Carbapenemase | Total no. of positives by real-time PCR | Phenotypic screen isolates |
|
|---|---|---|---|
| Total no. of positives by conventional PCR | Species isolated (no.) | ||
| KPC | 0 | 0 | |
| NDM | 22a | 20 | Citrobacter freundii (1) |
| Klebsiella pneumoniae (10) | |||
| Mixed C. freundii/K. pneumoniae (5) | |||
| Escherichia coli (4) | |||
| OXA-48 | 1b | 0 | |
a
Broth 102 and broth 220 both tested as phenotypically ertapenem and meropenem susceptible; however, both tested positive for NDM.
b
Broth 239 tested as NDM positive and OXA-48 positive, but only an NDM-positive E. coli was recovered from the broth. A repeat screen sample 1 week later had an OXA-48-positive K. pneumoniae isolated.
