Abstract excerpt

Avian infectious bronchitis virus (IBV), a major pathogen in the poultry industry, evolves rapidly via genetic mutations and recombination. While recombination between field and live vaccine strains is well-documented, its direct role in viral virulence remains unclear. In this study, four novel IBV field strains (SX/2407, SX/2408, SX/2409, SX/2410) were isolated from a single layer farm in Shanxi Province,...
