Evaluation of specific Fasciola antigen in the immunodiagnosis of human fascioliasis in Egypt.
Enzyme-linked immunosorbent assay (ELISA) and enzyme linked immunoelectrotransfer blot technique (EITB) were employed for the detection of circulating Fasciola antibodies in infected human sera using a specific Fasciola antigen, prepared by immunoaffinity purification of homogenates of Fasciola hepatica adult worms. Ninety two individuals diagnosed clinically and parasitologically were classified into: Fascioliasis group (21 patients), schistosomiasis group (21 patients) and subjects harbouring other parasitic infections (50 patients). Eighteen healthy individuals served as normal controls. ELISA was 100% sensitive and 93% specific with 96.5% diagnostic efficacy, whereas EITB was 100% sensitive and specific with 100% diagnostic efficacy. Our data revealed that ELISA can be used as a good screening test while EITB can serve as a confirmatory test for immunodiagnosis of fascioliasis.
