What is the life cycle of the trematode parasite that causes the most economic damage to ruminants?
1- The parasite penetrates the snail and forms a sporocyst.
2- Each sporocyst gives rise to 8 to 12 rediae.
3- The rediae give rise to cercariae that lose their tail in the water and become metacercariae.
4- The metacercariae are ingested by the definitive host and migrate to the liver.
5- The parasite matures and lays eggs that are eliminated in the feces.
6- The eggs hatch and the larvae penetrate the snail, completing the life cycle.

O ciclo de vida do parasita trematódeo que causa o maior dano econômico aos ruminantes é o seguinte: 1- O parasita penetra no caramujo e forma um esporocisto. 2- Cada esporocisto dá origem a 8 a 12 redias. 3- As redias dão origem a cercárias que perdem sua cauda na água e se tornam metacercárias. 4- As metacercárias são ingeridas pelo hospedeiro definitivo e migram para o fígado. 5- O parasita amadurece e põe ovos que são eliminados nas fezes. 6- Os ovos eclodem e as larvas penetram no caramujo, completando o ciclo de vida.
