  • Attenuated canine parvovirus vaccine
    Patent number: 5885585
    Abstract: The invention is directed to attenuated canine parvovirus (CPV) strains which may be used as a veterinary vaccine against CPV disease. The invention is further directed to a virus stock generated from a genomic DNA clone of the attenuated CPV strain which is used as a veterinary vaccine and is able to confer protective immunity to dogs against challenge with virulent CPV. Methods are given for the production of an attenuated CPV virus from a cloned CPV genome which may be used as a veterinary vaccine.
    Type: Grant
    Filed: May 15, 1996
    Date of Patent: March 23, 1999

  • Modified living canine parvovirus vaccine
    Patent number: 4303645
    Abstract: A safe, efficacious vaccine for protecting dogs against infection caused by canine parvovirus is produced by prolonged serial passages in non-oncogenic cell lines. One embodiment includes the use of sub-optimal temperatures (below that normal for the dog) during passaging.
    Type: Grant

    Patent number: 4213965
    Abstract: This invention relates to a vaccine against Canine Herpesvirus from a newly isolated small-plaque variant of Canine Herpesvirus, and to a method for producing small-plaque variant reduced pathogenicity canine herpesvirus.
    Type: Grant
    Filed: January 23, 1979
    Date of Patent: July 22, 1980
    Assignee: Cornell Research Foundation, Inc.

  • Canine parvovirus vaccine
    Patent number: 4193991
    Abstract: The present invention relates to the method of protecting dogs against canine parvoviruses. More specifically, the present invention relates to a method of producing an inactivated (killed) canine parvoviral vaccine from a native virulent strain of CPV for use as a vaccine in dogs against disease caused by virulent canine parvoviruses.
    Type: Grant
    Filed: December 20, 1978
    Date of Patent: March 18, 1980

    Inventors: Max J. G. Appel, Leland E. Carmichael
  • Heterotypic canine parvovirus vaccine
    Patent number: 4193990
    Abstract: A vaccine against disease caused by canine parvoviruses (CPV) is produced using a modified live (attenuated) or chemically inactivated feline panleukopenia virus vaccine.
    Type: Grant
    Filed: February 16, 1979
    Date of Patent: March 18, 1980
