Life Cycle
The rabbits ingest sporulated oocysts. Sporulated oocysts contain four sporozoites that hatch and travel via the hepatic portal vein to the liver, and eventually penetrate the bile duct epithelium, where they undergo asexual reproduction known schizogony. Rupture of the schizont consequently causes epithelial cell rupture and death. Merozoites will penetrate other cells and create more merozoites for one to several rounds. Eventually, a merozoite becomes a male microgamecyte and asexually reproduces in epithelial cells. A ruptured microgamecyte infects a cell with the female macrogamecyte and through sexual reproduction create a zygote. The zygote develops a protective shell before expulsion in the bile excreation and then the feces as an oocyst.

Famous quotes containing the words life and/or cycle:
“We believe that civilization has been created under the pressure of the exigencies of life at the cost of satisfaction of the instincts.”
—Sigmund Freud (1856–1939)
“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)
