查询词典 DC

The phylogenetic analysis showed that QH3,HLJ and A4 belonged to the genetype Ⅷ,Ⅸ,Ⅵ respectively. It indicated that not only NDV genetypes among epizootic strains isolated from different areas were evidently variable, but also special genetype DC which hadnt prevailed in abroad was present in China.
