Figure 7. Serological testing of serum samples from pig studies.

Figure 7

Four pigs from each group were infected. Mock-infected pigs (PBS) were included as controls. (A) ELISA of PRRSV antibodies in serum samples of 35 days post-infection (DPI). The S/P ratio above 0.4 is considered positive. Error bars represent standard errors of the ratios among the four pigs in each group. A2: A2MC2. (B) Virus-neutralization antibody assay against PRRSV VR-2332. The virus neutralization (VN) titers are shown as reciprocals of serum dilutions shown VN activity. Significant differences between the A2MC2 groups and the group of MLV-infected pigs are denoted by *and **, which indicate P < 0.05 and P < 0.01, respectively.
