Title:
NOVEL POLYPEPTIDE, DNA CODING FOR SAID POLYPEPTIDE, RECOMBINANT VECTOR CONTAINING SAID DNA, RECOMBINANT VIRUS PREPARED USING SAID VECTOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/1994/023019
Kind Code:
A1
Abstract:
A polypeptide exhibiting the antigenicity of Mycoplasma gallisepticum, a fused polypeptide comprising the above polypeptide and, connected to the N-terminus thereof, a signal membrane anchor of a type II outer-membrane polypeptide of a virus that infects birds, or a polypeptide capable of reacting with a mycoplasma-immune serum or a mycoplasma-infected serum and exhibiting a substantially pure antigenicity, respectively having amino acid sequences of about 32 kDa, about 40 kDa, or about 70kDa. The expression w ith a recombinant virus of a polypeptide modified to such an extent as to exhibit an antigenicity equivalent to that of any of the above polypeptides. The use of a recombinant virus as a live vaccine.
