摘要:
A recombinant virus that is more potent as an antimycoplasma vaccine is provided by preparing a DNA encoding a fused protein comprising a polypeptide having the antigenicity of Mycoplasma gallisepticum and a polypeptide derived from the outer membrane protein of a herpesvirus, wherein the latter polypeptide is connected to the N-terminal side of the former polypeptide, and integrating the prepared DNA into a region non essential for the proliferation of avipoxviruses to prepare a recombinant avipoxvirus.
