| Abstract: | An antigen was prepared from metabolic products which were produced by maintaining Fasciola hepatica adults in RPMI tissue culture medium for 24 h. The antigen compared favourably with a soluble extract of adult flukes when used in an enzyme-linked immunosorbent assay (ELISA). Experimentally infected calves were used to evaluate the sensitivity of the test and a survey from areas of both traditionally high and low incidence of the disease was carried out. Evidence is presented which suggests that this metabolic antigen could be used for the sero diagnosis of naturally occurring infections. In addition the use of a microcomputer to read, file and analyse the results enabled a very large number of samples to be processed daily. |
