[Early diagnosis of liver fluke infection in sheep].

The sera and livers of slaughtered lambs were studied in October 1987 in order to achieve a suitable interpretation of the indirect haemagglutination assay (IHA) in the diagnosis of fascioliasis in flocks. In view of these studies, it is concluded that the IHA is useful in the early diagnosis of liver fluke infection in lambs. It is recommended to take samples from at least five lambs in each flock. An interpretation model is provided.
