Infection of ratites with clade 2.3.4.4b HPAIV H5N1: Potential implications for zoonotic risk

2025-09-10

Abstract excerpt

We detected H5N1 high pathogenicity avian influenza in captive Greater Rhea ( Rhea americana ). Viral genetic analysis revealed the mammalian associated PB2-E627K mutation, indicating selection of mammalian-relevant mutations in ratites. Pathologic investigation of available tissues demonstrated severe multifocal necrotising inflammation, and a strong vasculotropism.
