The Phenotypic and Genotypic Detection of Carbapenem-Resistant Strains
| CR Species | Phenotypic Detection | Genotypic Detection | ||
|---|---|---|---|---|
| MHT n (%) | CDT n (%) | blaKPC n (%) | blaGES n (%) | |
| K. pneumoniae (n=36) | 36 (48) | 36 (48) | 36 (48) | 36 (48) |
| A. baumannii (n=19) | 19 (25.4) | 19 (25.4) | 19 (25.4) | 19 (25.4) |
| E. coli (n=7) | 7 (9.3) | 7 (9.3) | 7 (9.3) | 7 (9.3) |
| E. aerogenes (n=3) | 1 (1.3) | 1 (1.3) | 2 (2.6) | 1 (1.3) |
| P. aeruginosa (n=10) | 7 (9.3) | 6 (8) | 10 (13.3) | 10 (13.3) |
| Chi-square P value |
71.845 P<0.0001 |
74.714 P<0.0001 |
60.17 P<0.0001 |
63.039 P<0.0001 |
Note: The percentage was calculated according to the number of the phenotypic carbapenem-resistant strains (which were resistant to imipenem and meropenem) (n=75).
