Résumé
Cystic hydatid disease [Hydatidosis] is the most serious tape-worm infection prevalent in the cattle and sheep raising area of the world. Hydatidosis in man [as an accidental host] is caused by infection with the ova containing larval stage of Echinococcus granulosus. In the last decade, different techniques have been employed for sero-diagnosis of hydatidosis; as IHA, IFA, ELISA, CCLE [Counter Current Immuno-electrophoresis]. This paper evaluated the validity of ELISA and IHA. Since whole hydatid cyst fluid was used as a source of antigen for serodiagnosis. Thirty surgical and pathological hydatidosis proven patients were examined. The sensitivity and specificity of ELISA were 96.7% and 97.5% respectively, and that of IRA were 86.7%, and 95% respectively
