The HA latches on to sugar (glycan) molecule receptors on cells to cause infection. Avian (bird) influenza viruses -- like H5N1 -- have not infected people often because the human upper ...

"H5N1 reassorts with other avian influenza viruses quite frequently and even the current H5 HA protein that is infecting dairy cows and commercial poultry farms in the US has been shown to ...

global data and studies in animals have shown that A(H5N1) clade 2.3.4.4b viruses can cause severe disease and death. Sequencing of viruses from U.S. cases has shown no changes in the HA gene ...

That Gln226Leu mutation had been flagged in previous studies of H5N1, which also hinted that it could boost the virus's ability to infect humans. However, most previous studies found that the HA ...

Highly pathogenic avian influenza A(H5N1) virus infection acquired in North America can cause severe human illness. Evidence for changes to HA that may increase binding to human airway receptors ...

"In addition, more research is also needed to assess whether these mutations in HA have had an impact on the late-wild bird lineage." H5N1 has been detected in 10,969 wild birds as of January 16 ...

Hemagglutinin, or the HA protein, latches onto the receptors of ... Antibodies directed against the stalks of H1N1 viruses can cross-react with H5N1, likely indicating some protection against ...

The Twist control contains synthetic RNA segments of the complete H5N1 HA and NA genome regions, which determine the subtype of the strain. Twist provides a suite of research tools and NGS ...

Recently, these viruses have been identified in many animal species, with HPAIV H5N1 HA clade 2.3.3.4b being the most predominant type in these spillover events. The U.S. Department of Agriculture ...
