Life Cycle
Opisthorchis viverrini is a hermaphroditic liver fluke. Its life cycle is similar to the life cycle of Clonorchis sinensis. It involves a freshwater snail, in which asexual reproduction takes place, and freshwater cyprinid fishes (family Cyprinidae) as intermediate hosts. Fish–eating (= piscivorous) mammals, including humans, dogs and cats, act as definitive hosts, in which sexual reproduction occurs. As a result of poor sanitation practices and inadequate sewerage infrastructure, Opisthorchis viverrini-infected people pass the trematode's eggs in their feces into bodies of fresh water.

Famous quotes containing the words life and/or cycle:
“Only those who know the supremacy of the intellectual life ... can understand the grief of one who falls from that serene activity into the absorbing soul-wasting struggle with worldly annoyances.”
—George Eliot [Mary Ann (or Marian)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
