| IgG2c | 1044.1 ± 199.8 | 25.12 ± 4.4 | 146.8 ± 24.0 | 24.9 ± 5.3 | 865.3 ± 88.3 | 22.1 ± 3.0 |
| Th1/Th2 a | 5.1 ± 1.0 | 5.06 ± 1.0 | 6.3 ± 1.2 | 6.3 ± 1.2 | 4.2 ± 0.4 | 4.2 ± 0.4 |
| IgA | 90.1 ± 9.8 | 2.26 ± 0.2 | 57.4 ± 6.6 | 10.0 ± 1.6 | 65.7 ± 2.9 | 1.6 ± 0.1 |
Results are expressed as mean ± S.E.M and relative percentage. a Th1/Th2 ratio refers to the relationship between IgG2b + IgG2c and IgG1 + IgG2a, respectively. Results derived from n = 6 for dams and n = 16 for pups.
