[The ELISA test in immunodiagnosis of human hydatidosis. Preliminary observations].

An evaluation of the E.L.I.S.A. method, compared to the indirect hemagglutination (I.H.) and to the counterimmunoelectrophoresis (CIEP) tests for the biological diagnosis of hydatidosis, was performed on 31 sera of patients, carrier of hydatid cysts, on 17 sera of patients with other infectious and parasitic diseases, and on 7 sera of blood donors. The immunoenzymatic test turned out positive in 30 out of the 31 sera of the patients with active hydatidosis (96.7%), while IH and CIEP turned out positive in 29 cases (93.5%). The control sera from patients with other diseases proved to be all negative, except one from a patient with active schistosomiasis. E.L.I.S.A. test was constantly negative with the sera of normal subjects. The validity and usefulness of E.L.I.S.A test for the diagnosis of the hydatid disease is discussed.
