文摘

Infectious bronchitis virus (IBV) causes a respiratory disease in domestic chickens worldwide.

Duck enteritis virus (DEV) was used as viral vaccine vector in chickens.

Recombinant DEV (rDEV) expressing IBV N, S, or S1 conferred protection against IBV.

Covalent vaccination with rDEV-N & rDEV-S1 conferred higher level of protection against IBV.
