Abstract
A vaccine against disease caused by canine parvoviruses (CPV) is produced using a modified live (attenuated) or chemically inactivated feline panleukopenia virus vaccine.
Description
HETEROTYPIC CANINE PARVOVIRUS VACCINE
Background of the Invention
The present invention relates to the method of protecting dogs against disease caused by canine parvovirus (CPV). More particularly, it relates to a method of immunizing dogs against CPV by using an alien infectious material from one animal species for the protection against natural disease in a different animal species. The vaccine that is the subject of this invention is a modified live (attenuated) or chemically inactivated feline panleukopenia virus vaccine.
Parvoviruses are characterized as a small animal DNA virus, consisting of an isometric protein capsid and a short molecule of single-stranded DNA. Until recently, there had been no definite isolation and laboratory propagation of a canine parvovirus, although parvoviruses have been recovered and isolated from various animal species (Siegl, The Parvoviruses, Springer-Verlag, New York, 1976), Bachmann et al, include the dog as a possible parvovirus host in a report detailing the characteristics of parvovirus in general (Bachmann et al., Intervirology 10: in press, 1978). In 1970, Binn et al. reported the recovery and characterization of a "minute virus of canines" (MVC) (Binn et al., Infect, Immunity 1; 503, 1970), The isolates described were of canine origin, however, their pathogenicity was not known, and cytopathic effect (CPE) was produced in only a very narrow host range, i.e., only in a single continuous canine cell line, and not in primary canine nor primary or continuous cell cultures from other species. No immunological testing was done. Present data suggest that the Binn isolate is distinct from the pathogenic canine parvovirus which is the subject of this application. In 1977, Eugster and Nairn reported a circumstantially-suggested causative link between diarrhea in puppies and a canine parvovirus (Eugster and Nairn, Southwestern Veterinarian 30: 59, 1977), Consistent with Binn et al., above, the isolate reported therein could not be grown in more than a single cell line. Again,
pathogenic potential was unexamined and no animal inoculations were performed. In 1978, an apparently new serious enteric disease in canines appeared and became widespread. It is characterized by diarrhea, fever, and diminished white blood cell counts.
The object of this invention is to provide a heterotypic feline viral vaccine for the protection of dogs against disease caused by pathogenic canine parvoviruses. While attempting to develop a homotypic vaccine against canine parvoviruses it was discovered that both living and inactivated commercial feline vaccines, when administered to dogs, provided protection against disease caused by CPV. The cross-relation between the feline panleukopenla virus (ΕPV) and the canine parvovirus (CPV) is a surprising result since such cross-relations are unusual among the various parvoviruses from different animal host species, e.g., swine-canine, bovine-swine, swine-feline, etc. (Siegl, G., "The Parvoviruses", Virology Monographs 15: Springer-Verlag, New York, 1976), The discovery of this immunological cross-relation represents a distinct advance in the art. One group of dogs was vaccinated with a commercial modified living (attenuated) feline panleukopenia viral (FPLV) vaccine (Vacc. A); a second group was inoculated with a commercially available chemically inactivated feline panleukopenia viral vaccine (Vacc. C); and a third group with inactivated FPLV vaccine prepared in our laboratory by growing living attenuated FPLV (Leopard strain) (Vacc. L) in CCL 64 cells and by inactivating the vijrus with.0,25% formalin. According to the manufacturer, both commercial feline viral vaccines were produced by growing the FPV in cell cultures Ctissue culture origin), The tissue cultures used for inactivated vaccine were treated with formaldehyde solution to insure viral inactivation. The vaccines were administered intramuscularly to dogs in doses of 1 cc. Neither the living nor inactivated FPLV vaccines caused any adverse effects in dogs during a 2-week period of observation prior to challenge-inoculation with virulent canine parvovirus. The vaccinated dogs
in groups 1 and 2 and unvaccinated control dogs were challenge-inoculated 14 days after administration of one dose of FPLV living or inactivated vaccine. Dogs in group 3 were vaccinated twice, two weeks apart, and challenge-inoculated seven days after the last vaccination.
EXAMPLES The results of vaccination with live feline panleukopenia vaccine are shown in Tables 1 and 2,

*Numbers indicate total white blood cell (WBC) count × 103. **Numbers indicate total lymphocyte count (L) × 103. +Vacc. C. indicates- dogs given a single 1 ml injection of inactivated FPLV vaccine (CU, strain). ++ Vacc. L. indicates dogs given two 1 ml injections two weeks apart, of inactivated FPLV vaccine (Leopard strain).
In addition to relative lymphopenia one or more days following challenge inoculation, control dogs had temperatures in excess of 103.0º one or more post-challenge days. Vaccinated dogs remained normal.
AH dogs vaccinated with the attenuated living or inactivated feline panleukopenia vaccines were protected, i.e., their resistance to virulent CPV was markedly enhanced. Protection was measured by the failure of vaccinated dogs to develop signs of disease (fever or relative lymphopenia), and, prior to challenge with virulent canine parvovirus, the development of canine parvovirus hemagglutinin-inhibiting antibody responses. The unvaccinated control dogs were all susceptible.
Hemagglutination (HA)/Hemagglutination Inhibition (HI) tests for CPV. Hemagglutination tests were performed at 2°C - 4ºC with 1% pig erythrocytes (PRC) at pH 7.4. The highest dilution of antigen in 0.05 ml giving 2+ HA was the endpoint. For the HA-HI tests the sera specimens were treated with a receptor-destorying enzyme (RDE) (Microbiological Associates, Cat. #30899). If isoagglutinins in the canine test serum for PRC were greater than 1:20, the serum was absorbed with 0.1 ml of 50% packed swine erythrocytes. Serum dilutions were started at 1:20 and two-fold dilutions were made using 0,025 ml diluters, 0.025 ml of antigen diluted to contain 4-8 units of HA was added and the mixtures were incubated fop one hour at room temperature. The PRC suspension (0.05 ml)was added, mixed, and the test was incubated at 2°C - 4°C for 2-4 hours, The highest dilution of serum that inhibited HA by 4-8 units of CPV antigen was the endpoint. The hemagglutination-inhibition titer was expressed as the reciprocal of the highest endpoint serum dilution (Tables 1 and 3),
The peripheral white blood cell and lymphocyte counts of both vaccinated and control groups are shown in Tables 2 and 4. Feline panleukopenia virus is available from the American Type Culture Collection, Rockville, Maryland, U.S.A., under accession number VR-648.
Claims
1. The prophylatic use of a vaccine comprising a modified live or chemically inactivated feline panleukopenia virus vaccine to protect dogs against disease caused by virulent canine parvovirus.
2. A vaccine for protecting dogs against disease caused by virulent canine parvovirus comprising a modified live or chemically inactivated feline panleukopenia virus vaccine.
3. A method of protecting dogs against disease caused by virulent canine parvovirus which comprises inoculating the dog with a modified live or chemically inactivated feline panleukopenia vaccine.
