H9N2 viruses commonly have alanine at HA1 position 180 (A180), which correlates with a preference for binding of 3SLN, viruses with glutamic acid (E180) generally show greater binding avidity for 6SLN; and viruses with valine (V180) have been shown to show appreciable binding to 6SLN, together with greater replicative fitness in mammals than viruses with A180 (17,35,36).
