An immunoblot assay was tested to evaluate its ability to diagnose human hydatidosis and to analyse the reactivity of hydatid patients' sera with the subunits of the 2 major Echinococcus granulosus antigens (5 and B). In all, 308 sera were examined: 166 sera from patients with clinically diagnosed hydatidosis, 100 sera from healthy control subjects, and 42 sera from patients with diseases other than hydatidosis. The sensitivity of the method was 90%, as compared to 78% with the immunoelectrophoresis/double diffusion test for antigen 5. No reactivity was found with 15 sera from patients with schistosomiasis, 7 sera from patients with trichinellosis, or 20 sera from patients with non-parasitic diseases. Analysis of serum reactivities showed the presence in all positive sera of antibodies directed against the 39 kDa molecule of the antigen 5 complex. A lower reactivity (55% of all hydatid sera) was observed with the subunits of the antigen B complex.
