Eight pairs of specific primers were designed and synthesized according to the sequences of Avian influenza virus(AIV) subtype H9N2 released in GenBank,and they were used in RT-PCR.In this way,3 isolates of AIV subtype H9N2 were obtained namely,A/chicken/Guangxi/1/00,A/chicken/Guangxi/14/00 and A/chicken;Guangxi/17/00 and their complete nucleotide sequences were analysed and compared.It was found that as demonstrated by homology and phylogenic analysis,higher homologues in the corresponding nucleotide seque...
