This study compares two H9N2 avian influenza lineages, finding the G57 genotype has higher replication, virulence, and transmission fitness in chickens than the G1-B lineage.

Haemagglutinin of US cattle and goat H5N1 binds only avian-type receptors and fuses at pH 5.9; seven emerging cattle mutations did not switch receptor preference.

This study evaluates HA functionality of UK H5N1 avian influenza viruses from 2020-2022, finding they retain strong avian phenotype with low zoonotic threat.

This paper identifies an H9N2 avian influenza virus mutant with a G149E mutation in HA that loses haemagglutination activity but retains replication fitness, highlighting challenges for vaccine and surveillance efforts.
