Furthermore as a significant essential agent for viral attachment release stability and virulence gC UL44 gene and its protein product glycoprotein C may play a key role in the epidemiological screening. The objectives of this study were to rapidly sensitively quantitatively detect gC gene of AHV-1 and provide the underlying basis for further investigating DNA vaccine in infected ducks by TaqMan fluorescent quantitative real-time PCR assay FQ-PCR with plasmid. Results The repeatable and reproducible quantitative assay was established by the standard curve with a wide dynamic range eight logarithmic units of concentration and very good correlation values . This protocol was able to detect as little as X 101 DNA copies per reaction and it was highly specific to AHV-1. The TaqMan FQ-PCR assay successfully detected the gC gene in tissue samples from and AHV-1 attenuated vaccine AHV-1 Cha strain inoculated ducks respectively. Conclusions The assay offers an attractive method for the detection of AHV-1 the investigation of distribution pattern of AHV-1 in vivo and molecular epidemiological screening. Meanwhile this method could expedite related AHV-1 and gC DNA vaccine research. Background Anatid herpesvirus 1 AHV-1 infection alternatively known as duck virus enteritis DVE or duck plague DP is one of the most widespread and devastating diseases of waterfowls in the family .
