Geographical distribution of antibody responses to lineage-specific synthetic peptides, as determined by ELISA.

EHC =  Endemic healthy controls (* a further 17 Colombian sera that were serologically negative with the lysate were included in the peptide ELISAs as additional controls); ND =  not determined.
athese 98 comprised 1 sample from each of 90 patients, plus 2 paired samples from each of 4 patients. All eight paired samples reacted with TSSApep-II/V/VI, and are included within the 67 Brazilian reactors to this peptide. 1 set of these pairs also reacted with TSSApep-V/VI.
