Porcine circovirus and Helicobacter combination vaccines and methods of use
InactiveUS20060029617A1Viral antigen ingredientsMicrobiological testing/measurementDiseasePorcine Circoviruses
The present invention is based on the discovery of novel species of the genus Helicobacter that are associated with gastro-esophageal ulceration in pigs. In particular, a novel species, H. cerdo, has been used as a source of antigenic material for the development of vaccine for the treatment of the gastro-esophageal disorders. Most advantageously, the novel Helicobacter and the porcine circoviruses associated with PMWS in pigs are useful for providing combination vaccines whereby immunogens derived from both types of pathogens may be codelivered to the target animal to stimulate the generation of protective antibodies and immunity. The invention, therefore, provides vaccines that are useful for the tratment of gastro-esophageal ulceration and PMWS in porcines. The present invention includes, therefore, multivalent immunogenic compositions and vaccines, multivaccine kits, and combined immunization or vaccination methods which make it possible to use such combined immunization or vaccination programmes.

An improved method for recovering the protein expressed by open reading frame 2 from porcine circovirus type 2 is provided. The method generally involves the steps of transfecting recombinant virus containing open reading frame 2 coding sequences into cells contained in growth media, causing the virus to express open reading frame 2, and recovering the expressed protein in the supernate. This recovery should take place beginning approximately 5 days after infection of the cells in order to permit sufficient quantities of recombinant protein to be expressed and secreted from the cell into the growth media. Such methods avoid costly and time consuming extraction procedures required to separate and recover the recombinant protein from within the cells.
