Abstract excerpt
Controlling duck plague (DP) is essential for waterfowl health and industry productivity. The herpesviral single-stranded DNA-binding protein ICP8 is essential for replication compartment assembly, yet its exploitation for vaccine development in avian herpesviruses is limited. In this study, we generated two ICP8 mutants (H825A and F829A/P830A) in duck plague virus (DPV) via BAC-based homologous recombination....
