Abstract

Composition of matter comprising the causative agent of Mystery Swine Disease, Lelystad Agent, in a live, attenuated, dead, or recombinant form, or a part or component of it. Vaccine compositions and diagnostic kits based thereon. Recombinant nucleic acid comprising a Lelystad Agent-specific nucleotide sequence. Peptides comprising a Lelystad Agent-specific amino acid sequence. Lelystad Agent-specific antibodies.

Claims

1. A method of producing an immunogenic composition, the method comprising:

introducing a purified preparation containing a polynucleotide encoding at least one polypeptide encoded by one or more open reading frames (ORFs) of ORFs 1-7 of a mystery swine disease virus, wherein the mystery swine disease virus is the isolate Lelystad Agent (CDI-NL-2.91) deposited Jun. 5, 1991 with the Institut Pasteur, Collection Nationale de Cultures De Microorganismes (C.N.C.M.) 25, rue du Docteur Roux, 75724--Paris Cedex 15, France, deposit number I-1102, into a suitable host cell;

culturing said suitable host cell; and

isolating one of the following therefrom;

a suitable host cell containing said polypeptide;

virus;

viral protein;

viral polynucleic acid;

or mixtures thereof.

2. The method according to claim 1, further comprising isolating at least one of a cultured host cell and a polypeptide encoded by said polynucleotide.

3. The method according to claim 1, wherein introducing a purified preparation containing a polynucleotide encoding at least one polypeptide encoded by one or more open reading frames (ORFs) of ORFs 1-7 of a mystery swine disease virus, into a suitable host cell comprises infecting the suitable host cell with a virus comprising the polynucleotide.

4. The method according to claim 1, wherein the mystery swine disease virus is characterized as being specifically reactive with serum antibodies of a sow, said serum antibodies obtained by intranasally inoculating a specific pathogen free sow with two milliliters of the virus identified as deposit number 11102, deposited Jun. 5, 1991 with the Insitut Pasteur, Paris, France (at passage level 3, titer 10.sup.4.8 TCID.sub.50/milliliter) and collecting serum antibodies from the thus inoculated sow after 25 to 33 days.

5. The method according to claim 4, further comprising isolating at least one of a cultured host cell and a polypeptide encoded by said polynucleotide.
