| Abstract: | Immunogenic potency of a killed feline panleukopenia virus vaccine against canine parvoviral enteritis in dogs was examined. The vaccine elicited hemagglutination-inhibition antibodies to canine parvovirus (CPV) in all of the 72 dogs which were vaccinated. The vaccine was protective in dogs against both experimentally induced and naturally occurring CPV-induced disease. By statistical analysis, 4 weeks was found to be the optimal spacing between 2 vaccinal doses resulting in hemagglutination-inhibition antibody titers up to 1:5,120. Adverse reactions to the vaccine were not observed. Atypical lymphocytes were found consistently in the CPV-infected control dogs. |
