Virus-specific IgG quantified by ELISA.
| Virus | IgG endpoint titer | Transfer ratio | ||||
|---|---|---|---|---|---|---|
| Dam | Colostrum | Cord | To colostrum | To cord | ||
| Canine parvovirus (CPV) | Mean | 47474 | 437154 | 1837 | 10.7 | 0.045 |
| Standard deviation | 54254 | 522299 | 3031 | 8.0 | 0.057 | |
| Number of samples analyzed | 41 | 37 | 129 | 37 | 118 | |
| Canine distemper virus (CDV) | Mean | 8968 | 54210 | 209 | 8.1 | 0.060 |
| Standard deviation | 21533 | 88096 | 411 | 6.3 | 0.047 | |
| Number of samples analyzed | 38 | 36 | 119 | 35 | 50 | |
Endpoint titers are presented as the reciprocal dilution at which antibody binding to antigen was detectable. Transfer ratios were calculated as the IgG endpoint titer in colostrum or cord divided by the corresponding IgG titer in the matched dam serum.
