Recombinant Bovine Herpesvirus Type I Expressing the Bovine Viral Diarrhea Virus E2 Protein Could Effectively Prevent Infection by Two Viruses.

ABSTRACT: Bovine respiratory disease complex (BRDC) is a comprehensive disease in cattle caused by various viral and bacterial infections. Among them, bovine herpesvirus type I (BoHV-1) and bovine viral diarrhea virus (BVDV) play important roles and have caused huge financial losses for the cattle industry worldwide. At present, vaccines against BRDC include trivalent attenuated BoHV-1, BVDV-1, and BVDV-2 live vaccines, BoHV-1 live attenuated vaccines, and BoHV-1/BVDV bivalent live attenuated vaccines, which have limitations in terms of their safety and efficacy. To solve these problems, we optimized the codon of the BVDV-1 E2 gene, added the signal peptide sequence of the BoHV-1 gD gene, expressed double BVDV-1 E2 glycoproteins in tandem at the BoHV-1 gE gene site, and constructed a BoHV-1 genetics
