Characteristics of the sera used to screen peptide microarrays.

Fecal egg counts (FEC; expressed as eggs per gram of stool (EPG) were based on a single stool sample. For STH, they represent the average FECs across single Kato-Katz, McMaster and Mini-FLOTAC method, whereas for S. mansoni, they represent the FEC based on a single Kato-Katz. For the Ascaris LungL3 IgG4 ELISA test, samples with an optical density ratio (ODr) of at least 0.08 were considered positive [27]. The grey cells indicate a positive test result for a given helminth or diagnostic test. Samples with an asterix (*) were included in both array experiments.
