Kinetics of anti-T. cruzi antibody levels. Samples of serum were harvested by cardiac puncture from mice used in three independent experiments and infected with the Y (▪), YpTEX (•), and YpTEX-CD40L (▴) strains. Using an ELISA, the optical densities corresponding to the anti-T. cruzi antibody levels were measured. Seven samples of serum from uninfected mice served as a control (optical density, 0.107). The data are means and standard errors of the means (n = 5). There was no statistically significant difference between YpTEX-CD40L and YpTEX (as determined by a Mann-Whitney U test).
