Antibody isotype levels against different
antigen preparations. Specific antibody isotype levels of the children included in this study from Murehwa, Mashonaland East province, Zimbabwe, against different Schistosoma haematobium antigen preparations: A: IgM against cercarial antigen preparation (CAP), B: IgM against soluble egg antigens (SEA), C: IgG against soluble worm antigen preparation (SWAP). Enzyme-linked immunosorbent assay (ELISA) optical density readings are classified according to S. mansoni cercarial transformation fluid rapid diagnostic test (SmCTF-RDT) results and infection status as determined by egg counts. (black circle) Egg-negative, (black square) Egg-negative, (red triangle) S. haematobium egg-positive, (inverted red triangle) S. mansoni and S. haematobium egg-positive, (red diamond) S. mansoni egg-positive. * P < 0.05, ** P < 0.01, ***P < 0.001.
