Fasciola hepatica
(Common liver fluke)
Material: | Pathogen demonstration: 3 – 6 walnut-sized stool samples, each 2 – 3 days apart, bile fluid Antibody detection: 1 ml serum (external service) |
Methods: |
Mikroskopie → Hellfeldmikroskopie Agglutinationsteste → Hämagglutination | Reference range | IHA (indirect hemagglutination assay): < 1: 160 titer |
Indication | Suspicion of infection with the common liver fluke with corresponding history |
Please note | Pathway of infection: Consumption of watercress or other raw water vegetables. The liver fluke penetrates the intestinal wall and migrates to the liver and bile ducts. Eggs are excreted 3 – 4 months after infection at the earliest. As eggs are passed irregularly and in low concentration, several stool samples should be tested. Infection can be inapparent or can lead to abdominal pains as well as fever (acute phase) or hepatocholangitic symptoms (chronic phase), eosinophilia, anemia due to blood drain by leeches, hyper-IgE-syndrome and weight loss. Serological tests are suitable for the early infectious phase when there is no egg excretion yet. |
