Mouse Response

• Immune Response: Significant humoral immune responses were induced by this DNA vaccine through intramuscular immunization. The IgG subclass (IgG1 and IgG2a) analysis indicates that divalent DNA vaccine induces both Th1 and Th2 immune responses (Chiang et al., 2009).
• Efficacy: Animals immunized with divalent vaccine demonstrated 70% survival after challenge with a dose of 5 × 108 CFU of A. pleuropneumoniae serotype 1 ten days after 2nd boost. Survival was significantly higher than that of the negative control groups (P < 0.05). No protective efficacy was observed for pcDNA3.1 vector immunization group and PBS control group and all mice were died within 24 h (Chiang et al., 2009).
• Host Ighg1 response
  • Description: Both IgG1 and IgG2a responses were induced by divalent DNA vaccine, with IgG1 slightly higher than IgG2a. The levels of IgG1 and IgG2a were also significant compared with the negative control groups (Chiang et al., 2009).

• Host Ighv1-9 response
  • Description: Both IgG1 and IgG2a responses were induced by divalent DNA vaccine, with IgG1 slightly higher than IgG2a. The levels of IgG1 and IgG2a were also significant compared with the negative control groups (Chiang et al., 2009).
