Prevalence of anti-Trypanosoma cruzi antibodies present in IgG fractions from chronic Chagas heart disease (cChHD) patients.
| % Prevalence | |||
|---|---|---|---|
| T. cruzi | TcP2β | R13 | |
| AV cChHD (group I) (n = 20) | 100 | 100 | 100 |
| Other rhythm disturbances cChHD (group II) (n = 10) | 40 | 40 | 40 |
| cChHD asymptomatic (group III) (n = 2) | 100 | 100 | 100 |
| HI | 0 | 0 | 0 |
(n = 20). Reactivity pattern of IgGs from cChHD patients (n = 32) against T. cruzi lysate, P2β protein and its derivate R13 peptide. The prevalence of specific antibodies was determined by enzyme-linked immunosorbent assay, considering the optical density values obtained for sera of HI (n = 20) (see Materials and methods). HI: healthy individuals.
