. molecular biological and biochemical studies on avian influenza virus receptors in different avian species

Avian influenza viruses are considered to be the key contributors to the emergence of human influenza pandemics. A major determinant of infection is the presence of virus receptors on susceptible cells to whichthe viral haemagglutinin is able to bind. Avian viruses preferentially bind to sialic acid α 2,3-galactose (SA α 2,3-Gal) linked receptors, whereas human strains bind to sialic acid α 2,6-galactose (SA α 2,6-Gal) linked receptors. The duck and chicken areFor this our research aimed to study the difference of the receptors of avian influenza viruses .
