Evidence for T Cell Help in the IgG Response against Tandemly Repetitive Trypanosoma cruzi B13 Protein in Chronic Chagas Disease Patients

Figure 2

Direct ELISA for total IgG reactivity to recombinant B13 protein in the solid phase. Comparison between CCC (subjects with chronic Chagas Cardiomyopathy) and ASY (subjects with indeterminate/asymptomatic form of the disease). ASY and CCC subjects (median Abs. = 0.756 versus 0.681, resp.). The box plots whiskers show median values and 25–75% percentile; the 10% and 90% percentile; ou tlier points are shown above and below the figure.
