The present invention discloses novel proteins, e.g., antigens, from Piscirickettsia salmonis. The present invention further discloses nucleic acids that encode these proteins. The present invention also discloses the use of the proteins, e.g., antigens, and nucleic acids to prepare vaccines against salmonid rickettsial septicemia (SRS). The present invention also discloses vaccines that can be used to protect fish from Piscirickettsia salmonis,as well as other pathogens. In addition, the present invention discloses methods of using the vaccines of the present invention to protect fish from SRS as well as from other pathogenic diseases.
摘要:
The subject invention provides a plant cell culture for producing proteinaceous agents comprising a plant cell line stably transformed to express a transgene encoding a proteinaceous agent and a growth medium which supports the growth of said plant cell culture but which does not support the growth of Mycoplasmataceae and contains no materials of animal origin. The plant cell line is capable of being continuously passaged such that consistent transgene expression is maintained during passaging. The plant cell line is also capable of being cryopreserved such that consistent transgene expression is recovered upon recovery from cryopreservation.

A vaccine comprises a portion of IHNV G protein and a portion of a second protein from a fish pathogen or their respective nucleic acid coding sequences. The presence of the IHNV G protein boosts the immune response to the second protein, resulting in a protective effect against infection by the fish pathogen from which the second protein is derived.

摘要:
The present invention is directed to a method to prepare an inactivated w/o emulsion adjuvated vaccine, wherein an aqueous solution comprising one or more inactivated angigens is mixed under mild conditions with a ready-made w/o emulsion. Preferably the vaccine is prepared just prior to vaccination. The aqueous solution and w/o emulsion are stirred or shaken by mechanical means or by hand. The present invention also relates to a kit of parts for use in a method according to the invention.

This invention also provides methods of immunizing an animal against bacterial disease.
摘要:
The present invention relates to the use of a diluent for the in-use stabilisation of cells infected with a cell- associated alphaherpesvirus. Contrary to the long-standing practice of incorporating a considerable amount of peptone into the diluent for such virus-infected cells, it was found that a reduction of the amount of protein in the diluent improved the in-use stability of alphaherpesvirus-infected cells. Whereby the best stability was even obtained using a protein-free diluent. This effect was especially pronounced for recombinant HVT viruses expressing a heterologous insert. Being protein-free is highly advantageous for the production of the diluent, in respect of costs, safety, and consistency of production.
