Reactivity against T. cruzi and the R3 peptide in sera from different T. cruzi–infected mice strains and adoptive transferred mice. (a) Sera from uninfected (open circles) or chronically infected (filled circles) BALB/c, CBA/J, and C57BL/6 mice were tested against a T. cruzi lysate and a R3 peptide using ELISAs. (b) Sera from adoptive CBA/J transferred mice was tested by ELISA with peptides from T. cruzi (R3T), mice (R3M), and humans (R3H) 2 months after transfer. Results are representative of three independent experiments.
