Table 2 Results of ELISAs to detect IgG1, IgG2 and IgG3 anti-filarial antibodies in serum samples from patients with various helminthiasis and healthy controls (non-endemic normals) using BmR1, Ov-BmR1 and Ll-BmR1. All antigens (tested separately) demonstrated identical results with all serum samples.

From: Homologs of the Brugia malayi diagnostic antigen BmR1 are present in other filarial parasites but induce different humoral immune responses
