^a*, serum samples from M. fascicularis; all other serum samples were from M. mulatta.

^bData are medians ± standard deviations. The MFI ratios do not represent quantitative antibody levels; they reflect relative signals obtained for serum sample reactions to the individual antigen-coated bead sets.
