Neutralizing activities of serum samples measured against FL01/DMa
| Virus | Neutralization titerb |
|---|---|
| PRRSV-01 | 98.7 |
| FL01 | 128 |
| FL01/GP3-D131N | 58.7 |
| FL01/GP5-S51N | 64 |
| FL01/DM | 45.3 |
a
The serum samples were from pigs infected with different viruses, and the samples were collected at 49 days p.i.
b
The neutralization titers were expressed as the geometric means of endpoint titers (n = 4 pigs per group). The differences observed among the means of titers were not statistically significant (P > 0.05 by one-way ANOVA).
