Recognition of antigenic components of Fasciola gigantica and their use in immunodiagnosis.

Antigenicity of the tegumental extract, excretory-secretory products and the whole somatic extract of Fasciola gigantica were evaluated to detect the most sensitive and specific antigen out of them that could be used as an immuno-diagnostic tool. Scanning electron microscopic study was carried out to have a full picture about the tegumental structure. The immunohistochemical staining technique was done using the indirect immunoperoxidase method on F.
