Establishment of the digital PCR assay for detection of Enterobacter cloacae
A droplet digital polymerase chain reaction (ddPCR) method for quantifying Enterobacter cloacae based on ampC gene was developed.The method was compared with real-time fluorescence PCR method and the probe concentration in ddPCR was optimized.The results showed that the optimized probe concentration was 400 nmol/L.The minimum DNA copies of E.cloacae was 8.9 copies/μL by the ddPCR method and the detection result was highly reproducible.It suggests that the ddPCR method established in this study is sensitive and specific,and can be used for the identification of E.cloacae.
