Abstract
PB2 E627K mutation of influenza A virus has been considered relevant to increased mammalian virulence and adaptation. In H7N9, the substitution is naturally confined to most human isolates and few low pathogenic avian isolates. However, we isolated two highly pathogenic H7N9 variants harboring PB2 627K from chickens in northern China.
Keywords: H7N9; Highly pathogenic; PB2 627K.
