Abstract

Hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of Echinococcus granulosus. Diagnosis of hydatidosis is still an unresolved problem. Serological tests are sensitive and include indirect haemagglutination, indirect immunofluorescence, immunoelectrophoresis, counter-current immuno electrophoresis, radio-immunoassay and mainly the ELISA. The aim of this study was the serodiagnosis of hydatid cyst in human using different antigens of sheep (hydatid fluid, Somatic and Excretory/secretory antigens of protoscolex) by ELISA and compares this result with commercial human ELISA kit. One hundred blood samples from patients with history of severe abdominal pain and eosinophilia were obtained. Ten serum samples were obtained from surgically and pathologically confirmed cystic echinococcosis patients from Mashhad university hospital as positive control and 5 serum samples from infant under one year old as negative control. Blood samples were centrifuged at 3000 x g at 20º C for 15 minutes and sera were stored at -20 º C. First, these samples were tested for the presence of antibody by commercial human ELISA. Then, ELISA was developed on microplates coated with hydatid fluid, Somatic and Excretory/secretory antigens of protoscolex of sheep. The results of this study as analyzed by Kappa test showed that, hydatid fluid antigen could be used as a precise source of detection in indirect ELISA test. In conclusion, hydatid fluid in comparison with Excretory-secretory and somatic antigens showed more compatibility = agreement in kappa test which can be used for further studies in development of any ELISA test for diagnosis of human hydatidosis.
