Agent: Dicrocoelium Dendriticum
Synonyms: Lancet fluke, small liver fluke

Dicrocoeliasis is a parasitic disease caused by the small liver fluke, D. dendriticum. It is a widespread problem worldwide in grazing livestock, and it is sometimes (although rarely) found in humans as well. However, because of its unusual method of transmission, human dicrocoeliasis remains a relatively rare occurrence unless one engages in riskier activities such as eating raw or undercooked liver. Cases of human dicrocoeliasis have been reported throughout eastern and western Europe, Africa, Australia, India, and Saudi Arabia.
