摘要： Outbreaks of duck Tembusu virus (DTMUV) have caused serious economic losses in China since 2010. In this study, an infectious clone of the DTMUV BZ-2010strain, isolated from layer cherry duck in China, was constructed using the bacterium-free infectious subgenomic-amplicons method. The subgenomic-amplicons of the human cytomegalovirus promoter (pCMV) at the 5' terminus of the first DNA fragment, the entire genome of DTMUV, and the hepatitis delta ribozyme followed by the simian virus 40 polyadenylation signal (HDR/SV40pA) at the 3' terminus of the last DNA fragment were synthesized and amplified by PCR in three DNA fragments. The pCMV and HDR/SV40pA were used to drive the viral RNA transcription and generate a full-length RNA transcript of the virus, and were found to be effective in reassembling DTMUV in duck embryo fibroblast cells. The RNA transcripts from the infection clone were infectious in duck embryo fibroblast cells, generating the reconstituted DTMUV. This study provided a valuable reverse genetic tool for the further study DTMUV pathogenesis.
