Production of serum IgG against B. hyodysenteriae before and after vaccination with the avirulent strain D28
| Group | Whole cell ELISA, D28 coated | Whole cell ELISA, B204 coated | ||
|---|---|---|---|---|
| Pre vaccination (day −13) | Post vaccination (day 17) | Pre vaccination (day −13) | Post vaccination (day 17) | |
| Vaccinated animals | 0.27 ± 0.17 | 0.31 ± 0.13 | 0.25 ± 0.16 | 0.23 ± 0.06 |
| Non-vaccinated animals | 0.19 ± 0.14 | 0.23 ± 0.17 | 0.21 ± 0.14 | 0.21 ± 0.09 |
The reaction of IgG with both the vaccination strain (D28) and the challenge strain (B204) are shown and presented as OD450 values with standard deviation.
