  • Method of treatment
    Patent number: 6299874
    Abstract: A method of producing active immunity against a viral disease in an animal subject comprises administering to the subject a vaccine conjugate consisting essentially of a live virus and a neutralizing factor bound to the live virus. The neutralizing factor is selected from the group consisting of antibodies and antibody fragments. The live virus is one capable of producing disease in the subject, and the antibody or antibody fragment is one capable of neutralizing the live virus. Preferred subjects are birds, a preferred virus is Infectious Bursal Disease Virus, and a preferred route of administration to birds is by in ovo administration.
    Type: Grant
    Filed: July 11, 2000
    Date of Patent: October 9, 2001
    Assignee: University of Arkansas

  • Method of treating Infectious Bursal Disease Virus infections
    Patent number: 5397569
    Abstract: A method of producing active immunity against a viral disease in an animal subject comprises administering to the subject a vaccine complex consisting essentially of a live virus and a neutralizing factor bound to the live virus. The neutralizing factor is selected from the group consisting of antibodies and antibody fragments. The live virus is one capable of producing disease in the subject, and the antibody or antibody fragment is one capable of neutralizing the live virus. Preferred subjects are birds, a preferred virus is Infectious Bursal Disease Virus, and a preferred route of administration to birds is by in ovo administration.

  • Method of treating infectious bursal disease virus infections
    Patent number: 5397568
    Abstract: A method of producing active immunity against infectious bursal disease virus in an avian subject comprises administering to the subject a vaccine complex consisting essentially of a live virus and a neutralizing factor bound to the live virus. The neutralizing factor is selected from the group consisting of antibodies and antibody fragments. The live virus is one capable of producing disease in the subject, and the antibody or antibody fragment is one capable of neutralizing the live virus. A preferred route of administration to birds is by in ovo administration.

  • Avian interleukin-2
    Patent number: 5034513
    Abstract: A substantially pure species of avian Interleukin-2 has a molecular weight of about 30 kda. as determined by SDS-polyacrylamide gel electrophoresis. The compound is obtained from avian lymphocytes. It is produced by collecting lymphocytes from an avian donor, growing the lymphocytes in a medium containing a T cell mitogenic agent, and recovering the compound from the medium.

  • Method of treating birds
    Patent number: 5028421
    Abstract: A method of treating birds by administering birds in ovo a T-cell growth factor comprising avian IL-2 is disclosed. The method is preferably carried out on chickens with 30K chicken IL-2 on about the eighteenth day of incubation. The method may be employed to increase the weight of treated birds after hatch. A vaccine may optionally be administered concurrently with the avian IL-2.
