Abstract: In recent years, bacterial drug resistance has become a major challenge to public health, with carbapenem-resistant Enterobacteriaceae (CRE) being particularly resistant to antibiotics. The main resistance mechanism of CRE is the production of carbapenemases, which are carried differently by different strains and encode different resistance genes; therefore, early detection of carbapenemases and resistance genes plays an important role in controlling the spread of drug-resistant bacteria. The current phenotypic assays for carbapenemases are the modified Hodge assay, the carbapenem inactivation assay, the Carba NP assay, the immunological assay, and mass spectrometry. For the detection of genotypes, there are real-time fluorescence quantitative PCR assay microarray technology, isothermal amplification assay and sequencing technology, all of which are widely used in the detection of carbapenemases. Understanding the advantages and disadvantages of each detection technology is very important for the selection of the most appropriate detection method in practical applications, this paper focuses on the research progress of CRE carbapenemase detection methods and the advantages and disadvantages of each method are reviewed, to provide data support for the detection and prevention of CRE as well as the control of nosocomial infections.
