• Life Cycle of Gastrodiscoides hominis

  1. Adult worms lay unembryonated ovum

  2. Egg embryonates in freshwater, releasing miracidium to infect snail

  3. Miracidium develops into sporocyst, redia, tailed-cercaria in snail

  4. Cercaria infects aquatic plant as second intermediate host

  5. Metacercaria ingested from aquatic plant, excysts in duodenum
