Abstract

The present study was conducted to characterize maternal antibody status which haemagglutination inhibition(HI) titers against canine parvovirus(CPV) in the 15 puppies delivered from 3 dams. The range of HI titers of 5 puppies delivered from a mother dog(A) with HI titer of 1 : 1,024 were 1 : 16~1 : 64 at 1 day old before suckling, 1 : 512~1 : 1,024 at 2 days old after suckling, 1 : 512~1 : 2,048 at 1 week old, 1 : 256~l : 1,024 at 2 weeks old, 1 : 128~l : 512 at 3 weeks old, 1 : 128~l : 256 at 4 weeks old, 1 : 32~1 : 128 at 5 weeks old, 1 : 16~1 : 64 at 6 weeks old, 1 : 16~1 : 64 at 7 weeks old, and 1 : 16~l : 32 at 8 weeks old. After vaccination with DHPPL to canine parvovirus in 60 days and 80 days old puppies, 1 : 8~l : 32 at 9 weeks old, 1 :16~1 : 128 at 10 weeks old, 1 : 32~1 : 256 at 11 weeks old, 1 : 16~1 : 256 at 12 weeks old, 1 : 128~1 : 256 at 13 weeks old, 1 : 64~l : 512 at 14 weeks old, and 1 : 128~1 : 512 at 15 weeks old. The HI titers of 3 puppies delivered from a mother dog(B) with HI titer of 1 : 512 were 1 : 16 at 1 day old before suckling, 1 : 256~1 : 512 at 2 days old after suckling, 1 : 512 at 1 week old, 1 : 128~1 : 256 at 2 weeks old, 1 : 64~1 : 128 at 3 weeks old, 1 : 64~1 : 128 at 4 weeks old, 1 : 128 at 5 weeks old, 1 : 64~1 : 128 at 6 weeks old, 1 : 16 at 7 weeks old, and 1 : 8 at 8 weeks old. After vaccination with DHPPL to canine parvovirus in 60 day and 80 days old puppies, < : 8~l : 8 at 9 weeks old, < : 8 ~1 : 16 at 10 weeksold, 1 : 64~1 : 128 at 11 weeks old, and 1 : 256~1 : 512 at 12 weeks old. The HI titers of 7 puppies delivered from mother dog(C) with Hl titer 1 : 1,024 were 1 : 512~1 : 1,024 at 2 days old after suckling, 1 : 256~1 : 1,024 at 1 week old, 1 : 256~l : 1,024 at 2 weeks old, 1 : 64~1 : 512 at 3 weeks old, 1 : 64~1 : 512 at 4weeks old, 1 : 8~l : 64 at 5 weeks old, 1 : 8~1 : 64 at 6weeks old, 1 : 8~1 : 32 at 7 weeks old, and < : 8~1 : 8 at 8 weeks old. Antibody to CPV was transferred mainly from mother to progeny through the colostrum and the transferred maternal antibody was in proportion to the HI titer of the mother As the HI titer of maternal antibody in puppies was low, puppies have a rapid immune response and a massive rise in HI titer to vaccination against CPV compared with puppies haying high level of maternal antibody.
