Abstract: Feline immunodeficiency virus antigens from gp160 envelope protein, gp120 envelope protein and p24 gag protein, useful for the diagnosis, treatment, and prevention of FIV. The invention may also be used to purify FIV.

Abstract: A method for preventing canine coronavirus in dogs is disclosed which comprises administering to a dog a live or inactivated vaccine prepared from transmissible gastroenteritis virus of swine (a TGEV vaccine). An inactivated vaccine composition for use in such a method and a process for the manufacture of the inactivated vaccine composition are described.

Abstract: Molecular clones of feline leukemia virus isolates that encode (a) a prototype highly infectious, minimally pathogenic virus, (b) a variant genome that is replication-defective and associated with a fatal immunodeficiency in cats similar to AIDS (FAIDS) or (c) a chimeric genome that is replication-competent and induces FAIDS. These molecular clones may be used to generate cell lines producing infectious virus which is useful in the preparation of vaccines or in the generation of viremia or disease challenge systems.

Abstract: This invention provides a recombinant raccoon poxvirus that express the envelope protein of Feline Immunodeficiency Virus. The recombinant viruses are useful as vaccines, either alone or in combination with carries and adjuvants.

Abstract: The present invention broadly relates to a therapeutic agent effective in mitigating disease associated with Feline Leukemia Virus (FeLV) in a feline infected with FeLV. A feline is an animal of the family Felidae. The novel therapeutic agent is composed of feline excised lymph nodes which have been subjected to mitogenic stimulation for their expansion dispersed in a pharmaceutically-acceptable carrier. Mitogenic stimulation conditions include culturing the excised lymph nodes in the presence of Interleukin-2. Optionally, culture conditions can include the presence of allogeneic or autologous FeLV tumor. The inventive therapeutic agent is prepared by excising lymph nodes from a feline infected the FeLV, mitogenically stimulating said excised lymph nodes for their expansion, and administering to the infected feline the expanded lymph nodes. Multidose regimens can be used as is necessary or desirable in convenient fashion.

Abstract: This invention provides a recombinant raccoon poxvirus that expresses the nucleocapsid and transmembrane proteins of Feline Infectious Peritionitis Virus. The recombinant viruses are useful as vaccines, either alone or in combination with carriers and adjuvants.

Abstract: A non-essential region in strains of live non-pathogenic immunogenic canine adenovirus is described. The insertion of genes from pathogenic carnivora viruses into this region, with suitable expression control systems, without prejudicing the stable reproducibility of the adenovirus vector is described. Such recombinant canine adenoviruses modified to contain a gene coding for an antigen or immunogenic agent, in association with an effective promoter for the gene, are described.

Abstract: A multivalent FeLV-infected feline vaccine composed of (1) a small but immunologically effective amount of inactivated feline leukemia virus; (2) a small but effective amount of an inactivated virus selected from the group consisting of Feline Rhinotracheitis Virus, Feline Calici Virus and Feline Panleukopenia Virus; and (3) a pharmaceutically acceptable immunologica adjuvant. Components (1) and (2) may be inactivated by any of the known techniques. The inactivated feline leukemia virus must be from subgroup A and is the Rickard isolate of the virus designated FeLV-A.sub.R1. This combination vaccine is effective in preventing Viremia, leukemia-associated syndromes, and deaths in cats caused by Feline Leukemia Virus, Feline Rhinotracheitis Virus, Feline Calici Virus and Feline Panleukemia Virus infections.

Abstract: The invention relates to antigenic preparations useful for inducing the production of antibodies in a cat which will bind to epitopes on feline leukemia virus. Also disclosed are immunogenic compositions and methods for immunizing a cat to enable the production of antibodies to feline leukemia virus.
