Serum cytokine and chemokine levels in individuals infected with
. The sera were from 34 patients with amebic liver abscess (ALA), 41 asymptomatic E. histolytica carriers (AC), and 24 individuals infected with the apathogenic E. dispar. Cytometric bead array analyses were used to determine the serum concentrations of IL-4, IL-10, IL-6, IL-1β, chemokine (C-C motif) ligand 2 (CCL2), and CCL3 in the sera from ALA patients, AC, and E. dispar-infected subjects (A–F). Statistics: Kruskal-Wallis test followed by Mann–Whitney U test with Bonferroni's correction (*p < 0.05, **p < 0.005, and ***p < 0.0001); ns, not significant. ALA, amebic liver abscess; AC, asymptomatic E. histolytica carrier; E. dispar, individuals infected with E. dispar.
