Wang et al. (2026) studied Infectious bronchitis virus (IBV) in chickens. IBV lineage GVII-2 was evaluated on Genomic characterization and pathogenicity. A novel IBV lineage (GVII-2) circulating in China since 2008 represents a unique serotype with strong tissue tropism and pathogenicity in specific-pathogen-free chickens.
