Comparison of virus-neutralizing titers against CDV strains
| Dogsa | VN titer (PRNT75)b |
||
|---|---|---|---|
| KDK-1 | 246 | Onderstepoort | |
| No. 1 | 1:8000 | 1:320 | 1:160 |
| No. 2 | 1:8000 | 1:640 | 1:160 |
| No. 3 | 1:8000 | 1:320 | 1:320 |
| No. 4 | 1:4000 | 1:640 | 1:160 |
a
Four SPF dogs were experimentally inoculated with KDK-1 via oral route and sera were collected at 4 weeks after final inoculation. Nos. 1 and 2 were inoculated once and Nos. 3 and 4 were twice at an interval of 4 weeks (Mochizuki et al., 2002).
b
Since VN titer of KDK-1 strain was over 1:1280, sera were serially two-fold diluted from 1:1000 dilution.
