[The construction of poliovirus chimera and the analysis of its antigenic structure].

The construction of poliovirus chimera is an useful way to investigate the antigenic structure conformation of poliovirus. In this research, the poliovirus chimera containing a piece of antigenic fragment of hepatitis A virus was constructed for analysis of poliovirus antigenic structure conformation. Depending on the characterization of this chimera, the conformation of poliovirus neutralization antigenic site I in VP1 was analyzed, and that the possible influence of hepatitis A virus antigenic fragment inserted to the structure conformation of poliovirus antigen was also investigated.
