Evaluation of the enzyme-linked-immuno-electro-diffusion-assay (ELIEDA) for the diagnosis of Schistosoma mansoni infection with low worm burden.

An immunoprecipitation technique, ELIEDA (enzyme-linked-immuno-electro-diffusion assay), was evaluated for the diagnosis of Schistosoma mansoni infection with low worm burden. One hundred of serum samples from patients excreting less than 600 eggs per gram of feces (epg), with unrelated diseases and clinically healthy subjects were studied. In patients with egg counts higher than 200 epg, the sensitivities of IgM and IgG ELIEDA were 1,000 and 0.

This method uses filtration with labelled antibodies to reveal precipitating systems preformed by immuno-electro-diffusion on cellulose acetate strips. IgG antibodies were demonstrated in the arc 5 and in 11 others bands.

Micropolyspora faeni is the principal allergen implicated in this disease which is very difficult to diagnose. The authors discuss the value of immuno-electro-diffusion on cellulose acetate which is a rapid and sensitive technique for the demonstration of remarkable precipitating systems: polysaccharide and chymotrypsin arcs.
