Abstract

A Fasciola hepatica tegument antigen preparation was obtained from intact adult worms by solubilization with a non-ionic detergent, Nonidet P-40. This antigen preparation contains antigens useful for the serodiagnosis of infection with this parasite. However, the antigen preparation is inadequate for use in the enzyme-linked immunosorbent assay (ELISA). The present work demonstrates that fractionation by demulsification of this antigen preparation with ammonium sulphate results in a soluble aqueous phase which contains F. hepatica serodiagnostic antigens which can then be applied to the ELISA. This F. hepatica tegument antigen preparation when used in the ELISA can detect rabbit fascioliasis two weeks after infection, with antibody levels peaking by 10 to 12 weeks of infection.
