Serum antibody titers against soluble amebic proteins (SAP) in individuals infected withE. histolyticaorE. dispar. Anti-amebic total immunoglobulin G (IgGt), IgG1, IgG2, IgG3, and IgG4 subclasses, and IgA titers were measured in 38 patients with amebic liver abscess (ALA), 44 asymptomatic E. histolytica carriers (AC), and 24 individuals infected with the apathogenic E. dispar. Statistics: Kruskal-Wallis test followed by Mann–Whitney U test with Bonferroni correction (*p < 0.05, **p < 0.005, and ***p < 0.0001).
