摘要
Abstract
A pair of primers and a TaqMan probe were designed according to the reported genomic sequence of Duck Tembusu virus (DTMUV) (GenBank accession No. JX273153) and an accurate and rapid real-time RT-PCR assay was then developed. The real-time RT-PCR method specifically detected DTMUV and had no cross-reaction with of other duck pathogens. The sensitivity of the assay was 25copies/μL. The linear correlation was observed at DNA concentrations from 2.5×101copies/μL to 2.5×107copies/μL. The equation of the assay was Ct=–3.323×Lg (conc)+43.70. The correlation coefficient was 0.997 and PCR efficiency reached up to 100%. Twenty-nine samples were collected from diseased ducks on different farms in Jiangsu and Anhui provinces and detected using this method. As a result, 27 samples were tested positive (93.10%). The real-time RT-PCR assay developed in the present study was a rapid, sensitive and specific method for reliable and quantitative detection of DTMUV, which can be used for clinical diagnostics and molecular epidemiology.关键词
