  • Patent number: 5871742
    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 antigenecity, respectively having amino acid sequences of about 32 kDa, about 40 kDa, or about 70 kDa. The expression with 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.
    Type: Grant
    Filed: September 25, 1995
    Date of Patent: February 16, 1999
    Assignees: Nippon Zeon Co., Ltd, Shionogi & Co., Ltd.
    Inventors: Shuji Saitoh, Setsuko Ohkawa, Sakiko Saeki, Ikuroh Ohsawa, Hirono Funato, Yoshikazu Iritani, Shigemi Aoyama, Kiyohito Takahashi
  • Patent number: 5766594
    Abstract: Antigen proteins of Mycoplasma gallisepticum, genes encoding the antigen protein, recombinant vectors integrated with the gene and hosts transformed with the vector are provided. Diagnostics and vaccine using the antigen protein produced by such hosts are effective for poultry, especially chicken infected with Mycoplasma gallisepticum. Vaccination can maintain poultry free of Mycoplasma gallisepticum infection.
