  1. A list of the 18 clusters of antigenic regions, which showed reactivity against at least 70% of the positive individual serum samples, did not show cross-reactivity against leishmaniasis-positive serum samples in the previous assay, and for which at least 90% of its regions were not similar to already known antigenic epitopes found in the IEDB. For each cluster, we show a representative antigenic region with the highest seroprevalence in CHAGASTOPE-v2. All 3868 antigenic clusters can be found in Supplementary Data S7.
  2. # Regions number of regions in said cluster, Sero seroprevalence, Rep repetitive (contains internal tandem repeats).
