Abstract:
It was demonstrated that there was significantly antigeni c drift in the influenza virus strains from Guangdong in 1996. It was the molecu lar basis of the variation on A、B、C、D and E domain encoded by HA gene, especi ally on A、C and E domain while the change of receptor binding domain played the slight roles in the 1996 influenza outbreak. In the other hand, the variation of No 145 and No 193 encoded by HA gene resulted in biological-feature changes of epidemical influenza isolates, which could be isolated and cultured by MDCK c ell-lines, but difficultly by embryonated-eggs.
