The life cycle resembles that of Fasciola spp, except the prepatent period is 30 weeks, and the entire life cycle takes ~7 months. Although flukes will mature in cattle, the intense encapsulation response forms a closed cyst, so eggs rarely pass out of the animal.

Can Fascioloides Magna infect humans?

Fascioloides magna does not affect humans directly because their main host involves animals from the Cervidae family or ruminants. However, Fascioloides magna has very adverse effects on livestock economics. If the parasite is ingested by sheep, they can do much damage to the animal.
