Efficient strategy to generate a vectored duck enteritis virus delivering envelope of duck Tembusu virus.

ABSTRACT: Duck Tembusu virus (DTMUV) is a recently emerging pathogenic flavivirus that has resulted in a huge economic loss in the duck industry. However, no vaccine is currently available to control this pathogen. Consequently, a practical strategy to construct a vaccine against this pathogen should be determined. In this study, duck enteritis virus (DEV) was examined as a candidate vaccine vector to deliver the envelope (E) of DTMUV. A modified mini-F vector was inserted into the SORF3 and US2 gene junctions of the attenuated DEV vaccine strain C-KCE genome to generate an infectious bacterial artificial chromosome (BAC) of C-KCE (vBAC-C-KCE). The envelope (E) gene of DTMUV was inserted into the C-KCE genome through the mating-assisted genetically integrated cloning (MAGIC) strategy, resulting in t
