Abstract excerpt

Infectious bronchitis virus (IBV), a highly contagious avian coronavirus, remains a major threat to global poultry production due to its rapid genetic evolution and frequent antigenic shifts. During a nationwide surveillance program in South Korea (2024-2025), we identified a previously unrecognized IBV lineage within dead birds in commercial chicken flocks. The Spike 1 (S1) gene of the IBVs belonging to this...
