Abstract excerpt

Infectious bursal disease virus (IBDV) remains a major threat to poultry production because of its immunosuppressive effects and its impact on flock performance. In 2023, a genotype A2d novel variant IBDV (nVarIBDV) was identified in Egypt and found to be closely related to strains circulating in China, raising concerns about the effectiveness of current vaccination strategies. This study evaluated the protective...
