Figure 1: BSA-specific IgE OD values for all healthy horses for a 1-year sampling period. Mean OD at each time point is represented by red X and standard deviation by red horizontal line. Each individual horse is represented by a circle in gray scale. Symbol * represents a time point that differed significantly from day 0 (p value <0.05).
Figure 2: BSA-specific IgE values for healthy horses aged 3-9 years. Each individual horse is labeled A-L, and colored bars represent time points of BSA-specific IgE measurement after vaccination. A blue star indicates post-vaccination time point where the fold change in anti-BSA IgE was greater than 1.5 when compared to Day 0.
Figure 3: BSA-specific IgE for reactor horses. Individual reactor horses are represented as blue circles for each of the time points when collected. Purple triangles depict the mean ELISA OD BSA-specific IgE value for the reactor horses at each time point. Red X depict the mean ELISA OD BSA-specific IgE value for healthy horses at each similar time point.
Figure 4: BSA-specific IgE mean OD values of the index case at 12 hours of life (purple bar), unvaccinated horses (blue bar), healthy horses at Day 0 (green bar), commercial donor horses (N=10) (yellow bar), reactor horses at ~ 24 hours post-vaccination (red bar), and the commercial plasma treatment administered to the index case (orange bar).
