polypeptide, dna beinhaltender actually, this dna, recombinant vector, a recombinant virus production using this vector and its application

摘要

A polypeptide showing an antigenicity to Mycoplasma qallisepticum, a fused polypeptide of said polypeptide ligated at the N terminus thereof with a signal membrane anchor of type II external membrane polypeptide of virus that infects to fowl, or a polypeptide showing an antigenicity which is substantially pure and reactive with Mycoplasma-immunized sera or Mycoplasma-infected sera, and having an amino acid sequence of about 32 kilodaltons, about 40 kilodaltons or about 70 kilodaltons, expression thereof or a modified polypeptide to such an extent that shows an immunogenicity equivalent to that of said polypeptide using a recombinant virus, and use of the recombinant virus as a live vaccine.
