Abstract
Carbapenem-resistant Enterobacteriaceae (CRE), especially carbapenemase-producing CRE (CP-CRE), have emerged as a major class of bacterial pathogens. They are frequently associated with high mortality and morbidity due to their unprecedented multi- or pan-drug resistance, in addition to the absence of standardized, clinically effective detection methods for early identification. Consequently, there is an urgent need for rapid and accurate detection of carbapenem resistance in clinical laboratories, as it is imperative for patient treatment, infection control, and epidemiological studies aimed at limiting further spread of CRE. A number of nucleic acid- and non-nucleic acid-based methods for rapid molecular detection of CRE are currently available or in development. Molecular detection of CP-CRE, in comparison with conventional culture-based phenotypic tests, offers several advantages, including the rapid turnaround time, the definitive identification of specific carbapenemase types, and, in some cases, the ability to test directly from clinical specimens without the need for culture. In this chapter, we will discuss the performance characteristics of these molecular technologies achieved to date on molecular detection for CRE and particularly CP-CRE.
