IgG titer/lesion score correlation. Combined IgG titers for each animal group (1–7) against ApfA (A) and VacJ (B) were plotted against the average lesion score of each individual group. Pooled endpoint sera retrieved on the day of euthanasia (1 week after challenge) were used. Statistical analysis by Pearson two-tailed r test showed a significant correlation between average IgG titers and lesion scores (ApfA P = 0.04; VacJ P = 0.03).
