Abstract
Although H5N1 influenza viruses have been responsible for hundreds of human infections, these avian influenza viruses have not fully adapted to the human host. The lack of sustained transmission in humans may be due, in part, to their avian-like receptor preference. Here, we have introduced receptor binding domain mutations within the hemagglutinin (HA) gene of two H5N1 viruses and evaluated changes in receptor binding specificity by glycan microarray analysis. The impact of these mutations on replication efficiency was assessed

The impact of these mutations on replication efficiency was assessed <italic>in vitro</italic> and <italic>in vivo</italic>. Although certain mutations switched the receptor binding preference of the H5 HA, the rescued mutant viruses displayed reduced replication <italic>in vitro</italic> and delayed peak virus shedding in ferrets. An improvement in transmission efficiency was not observed with any of the mutants compared to the parental viruses, indicating that alternative molecular changes are required for H5N1 viruses to fully adapt to humans and to acquire pandemic capability.</p></div></front></TEI><affiliations><list><country><li>Danemark</li><li>États-Unis</li></country><region><li>Californie</li><li>Géorgie (États-Unis)</li><li>Massachusetts</li></region></list><tree><country name="États-Unis"><region name="Géorgie (États-Unis)"><name sortKey="Maines, Taronna R" sort="Maines, Taronna R" uniqKey="Maines T" first="Taronna R." last="Maines">Taronna R.
