Abstract

The fascioliasis is a parasitic disease caused by two species of trematodes, Fasciola hepatica and Fasciola gigantica. Considered a zoonosis with wide geographical distribution, is able to limit the creation of several species of domestic animals of zootechnical interest, and affect men as occasional host, there were approximately 180 million people at risk of infection and estimated that about 2.4 million are already infected. The prevalence is high in areas that are creations of ruminants. Consisting of the most relevant parasitic disease in animals of economic interest in the world, its importance is due mainly to losses associated with condemnation of livers, mortality, reduction in production of meat, wool and milk, to secondary bacterial infections, the interference with fertility and the costs of anthelmintic treatments (fasciolicidas). Thus, the objective with the present review was to describe the importance of diagnosis and treatment of liver fasciolosis in cattle.
