ABSTRACT
Enterococcus faecium is responsible for a highly contagious, drug-resistant nosocomial infection that often causes serious illness. In this study, a rapid and sensitive RPA-LFS (recombinase polymerase amplification-lateral flow strip) method for the detection of E. faecium was established based on specific primers and probes designed using the ddl gene. To verify the specificity and sensitivity of the method, 26 specific strains and 100-106 CFU/µL E. faecium were selected for detection. The results show that the proposed method can specifically detect E. faecium, and the minimum detection limit is 100 CFU/µL. To compare the clinical application of the method with qPCR, 181 clinical samples were collected for testing. RPA-LFS and qPCR had the same practical applicability, and 61 parts of E. faecium were detected in 183 clinical samples. The methods developed in this study not only have the advantages of rapid sensitivity and specificity but also meet the needs of remote areas with scarce medical resources.
