In #turkeys, unlike #chickens, non-structural #NS1 #protein does not play a significant role in #replication and tissue #tropism of the #H7N1 avian #influenza virus, Virulence: https://www.tandfonline.com/doi/full/10.1080/21505594.2024.2379371

These results suggest that NS1 does not play a role in the virulence or replication of HPAIV H7N1 in turkeys and further indicate that #genetic determinants of HPAIV differ in these two closely related galliform species.
