Abstract

A promising serological field test for schistosomiasis could be developed by means of an immunohistoperoxidase procedure in the Defined Antigen Substrate Spheres (DASS) system. Sera of individuals with Schistosoma mansoni infections were examined with the DASS-system, using peroxidase labeled conjugates. The results were compared with those obtained with the Indirect Fluorescent Antibody (IFA) technique on frozen sections of the adult parasite. The DASS-system proved to give specific positive reactions at higher serum dilutions than the IFA-technique. The results of the test could readily be observed with the naked eye.
