  • 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

  • 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.

  • Method of treating immature birds with IL-2
    Patent number: 5106617
    Abstract: A method of causing an animal to gain weight by administering that animal a T-cell growth factor comprising Interleukin-2 (IL-2) in an amount effective to cause that animal to increase in weight is disclosed. A method of treating birds by administering birds in ovo avian IL-2 is also disclosed. The method is preferably carried out on chicken 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.
