Serum titration curves of enzyme-linked immunosorbent assays comparing absorbance values for serial dilutions of pooled positive (solid lines) and negative (dashed lines) control sera from humans (A) and dogs (B). Absorbance values for immunoglobulin G (IgG) and IgM antibodies to Trypanosoma cruzi are represented by triangles and diamonds, respectively.
