Canine plasma samples tested with a multiplex bead array correlate with initial conventional serology results. Reactivity to 11 T. cruzi recombinant proteins in sera or plasma from conventional serology positive (seropositive) and negative (seronegative) dogs living in a T. cruzi-endemic region of Argentina and canine sera obtained from dogs in the United States. Vertical bars represent mean fluorescence intensity (MFI) to the recombinant protein on a scale from 0 to 30 000 arbitrary light units. Recombinant GFP and T. cruzi lysate-coated beads served as negative and positive controls, respectively.
