2026-06-04 Molecular Adaptation Predicted PTM sites in Influenza A virus proteins exhibit host-associated evolutionary rate differences, indicating molecular adaptations related to host lineage. 42240086
2026-05 Molecular Adaptation H7N9 isolates showed molecular adaptations for mammalian infection, including an HA 186V mutation and new glycosylation sites linked to immune evasion. 41747464
2026-05 Cross Species Transmission H7N9 avian influenza virus circulates among wild birds and poultry, with isolates of chicken and quail origin demonstrating avian-to-avian cross-species transmission potential. 41747464
2026-05 Host Range Experiment H7N9 Group.y.2.3 isolates exhibited increased replication and virulence in chickens compared to other isolates, indicating lineage-dependent host adaptation in poultry. 41747464
2026-05 Host Range Experiment Experimental infection of chickens and mice with H7N9 isolates showed that Group.y.2.3 viruses replicated more efficiently and were more virulent than other lineages, demonstrating differential host susceptibility and cross-species adaptation potential. 41747464
2026-05 Spillover Event H7N9 avian influenza virus transmitted from wild birds and poultry to humans, causing severe respiratory disease and high mortality. 41747464
2026-05 Genomic Evolution Phylogenetic and molecular characterization of H7N9 isolates revealed two HA gene evolutionary lineages in poultry associated with differing virulence and mammalian adaptation potential. 41747464
