Correlation between α-toxin specific antibody isotype titers and neutralization titers. Plots represent the correlation between milk A IgG1, B IgG2, and C IgA titers with their respective milk neutralization titers, and the correlation between serum D IgG1, E IgG2, and F IgA titers with their respective serum neutralization titers. Titers pre-immunization (filled circle), post-prime (filled triangle) and post-boost (filled diamond) immunization are depicted. Spearman correlation coefficients were A 0.838, B 0.727, C 0.583, D 0.893, E 0.659, and F 0.621.
