Humoral response in the study population. Anti-leishmanial (total soluble Leishmania antigen [TSLA]) IgG in the plasma of endemic healthy controls (EHCs) (N = 25), asymptomatic Leishmania (N = 25), and healed visceral leishmaniasis (HVL) (N = 21) individuals was evaluated using enzyme-linked immunosorbent assay as mean ± standard deviation, OD₄₉₂ level. The bars represent the mean for the different groups. Data were analyzed between groups by the nonparametric Kruskal–Wallis test followed by the post hoc Dunn multiple comparison tests. NS = not significant; P < 0.05 is considered statistically significant. *** P < 0.001.
