Figure 2

Antibody levels following vaccination and challenge infection. Pigs were prime-boost vaccinated on D0 and D14 with three different experimental M. hyopneumoniae bacterins (Lipo_DDA:TDB, PLGA_TLR, SWE_TLR), challenge infected on D28–29 and euthanized on D56. M. hyopneumoniae-specific IgG (A) and IgA (B) antibodies in serum and M. hyopneumoniae-specific IgA in BAL fluid (C) were determined by indirect ELISA. Individual animals are shown. For each time point, significance was calculated using a Kruskal–Wallis ANOVA. The NCG was not included in the statistical analyses. Groups that have no superscript in common are significantly different from each other (P ≤ 0.05). NCG, non-challenge control group (PBS-injected, non-challenge infected); PCG, PBS-injected control group (PBS-injected, challenge infected).
