The trematode parasite Fasciola hepatica infects a wide variety of mammals, causing considerable economical losses in domestic animals. It is also an important zoonosis. The major pathology of fasciolosis is caused by immature flukes migrating in the liver parenchyma and later by adult flukes in the bile ducts. Egg related immunopathology, commonly observed in the closely related parasite Schistosoma sp., is not normally expected in fasciolosis because the parasite matures and produces eggs in the bile ducts. However, the paper reports a case of Fasciola hepatica-egg induced granuloma in a bovine liver parenchyma and discusses its significance in the pathogenesis of fasciolosis.
