The sensitivity and specificity of SjSP-216-based ELISA for early diagnosis of schistosomiasis. Ten mice and six rabbits were infected with S. japonicum. Sera were collected three weeks post-infection. The anti-SjSP-216 antibody levels of each sample were determined from the ratio of the OD450nm values to the cut-off values (determined from the mean plus three standard deviations from the sera, prior to infection). Data were expressed as the mean ± standard error. Sj-Mouse: S. japonicum infected mouse. Ctr-Mouse: Uninfected control mouse. Sj-Rabbit: S. japonicum infected rabbit. Ctr-Rabbit: Uninfected control rabbit
