Antibody isotype levels against different Schistosoma haematobium 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.
