Recognition of <i>r</i>Tc_11623.20 and <i>r</i>Tc_N_10421.310 by sera from C57BL/6 mice chronically infected with different <i>T. cruzi</i> strains.

<p>Sera from mice chronically infected with CL Brener (CL-B), Colombiana (Col) or Y (Y) <i>T. cruzi</i> strains, mice infected with <i>T. rangeli</i> (T.rang) or uninfected mice (C-) were screened by ELISA with <i>r</i>Tc_11623.20 (A), <i>r</i>Tc_N_10421.310 (B) or with a pool of these two recombinant proteins (C). The dotted line represents the cutoff value that was obtained based on the ROC curve. The solid line corresponds to the mean values. Col, mice infected with Colombiana; Y, mice infected with the Y strain; CL-B, mice infected with the CL Brener; T. rang, <i>T. rangeli</i>-infected mice. C-, uninfected mice.
