Serum antibody response to canine parvovirus, canine adenovirus-1, and canine distemper virus in dogs with status of immunization: study of dogs in Sweden.
1988
Olson P. | Klingeborn B. | Hedhammar A.
Serum antibody titers to canine parvovirus (CPV), canine adenovirus-1 (CAV-1), and canine distemper virus (CDV) were measured in dogs with known immunization status. The dogs represented 3 groups: nonvaccinated dogs less than 12 months old; vaccinated dogs less than 12 months old; and adult dogs greater than 12 months old. For practical reasons, the population from which the specimens were obtained could be considered as free from natural infection with CAV-1 and CDV. In nonvaccinated dogs less than 12 months old, antibodies against all 3 viruses were measured at the time the dogs were given their first vaccination. Altogether, 50.7% of the dogs had titer greater than or equal to 1:10 to CPV, and 26.1 and 46.2% had titer greater than or equal to 1:8 to CAV-1 and CDV, respectively. The concentration of maternal antibody seemed to be of major importance for failure of immunization with use of inactivated CPV vaccine, but not with CAV-1 and CDV vaccination. In dogs less than 12 months old and vaccinated against CPV infection with inactivated virus, only 11.5% had titer greater than or equal to 1:80. In dogs vaccinated against infectious canine hepatitis and canine distemper, 63.2 and 78.3%, respectively, had titer greater than or equal to 1:16. In adult dogs greater than 2 months old and vaccinated against CPV infection, less than 50% had titer greater than or equal to 1:80, regardless of time after vaccination. There was no significant difference in titer between vaccinated and nonvaccinated dogs. Approximately 60% of these dogs had titer greater than or equal to CAV-1 at all time intervals after vaccination. There was only a weak correlation between decrease of titers and time; this correlation could be explained by the fact that a proportion of the dogs had been vaccinated with inactivated CAV-1 virus. There was, however, no correlation between titer to CDV and time. The percentage of dogs with titer greater than or equal to 1:16 was at least 60%.
