Development and Application of TaqMan Fluorescent Real-time Quantitative PCR for the Detection of Egg Drop Syndrome Virus
摘要
Abstract
To establish the fluorescent real-time quantitative PCR (FQ-RT-PCR) assay for rapid detection of egg drop syndrome virus, a pair of primers and a TaqMan probe were designed according to the sequences from highly conserved regions of the hexon protein gene of egg drop syndrome virus (EDSV). A positive recombinant plasmid was employed as standard template for the construction of standard curve. The detection limit of the assay was 10 copies DNA · μL-1 and the FQ-RT-PCR was reproducible, as shown by satisfying its wide dynamic range from 10' to 108 copies DNA · μL-1. This assay is specific and has no cross-reaction with DNA of other avian virus. The quantity of EDSV in eggs after artificial infection with NE4 strain of EDSV were detected by using the developed FQ-RT-PCR method. Compared with common PCR assay, the FQ-RT-PCR method is more sensitive and more suitable for detection of egg drop syndrome virus in vivo and in vitro.关键词
