Indirect immunoperoxidase tests in the diagnosis of schistosomiasis.

An enzymatic technique, immunoperoxidase histochemistry, was applied in the diagnosis of human schistosomiasis. Sera of patients with S. haematobium, S. mansoni and mixed infection, together with control sera, were studied. The test proved easily applicable and gave reliable results particularly with S. mansoni and double infection. The depth of the colour reaction, was then compared with ELISA readings, but there was no relation in the results of the individual cases.
