Zusammenfassung: | 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 Mycoplasm 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 imnunogenicity equivalent to that of said polypeptide using a recombinant virus, and use c the recombinant virus as a live vaccine. |
