1. Nematodes (roundworms):
- Eggs are passed in the feces of infected individuals.
- Eggs hatch into larvae in the environment.
- Larvae can infect a new host through ingestion or penetration of the skin.
- Larvae migrate through the host's tissues and develop into adult worms in the intestines.
- Adult worms produce eggs, which are passed in the feces to continue the life cycle.
2. Cestodes (tapeworms):
- Eggs or larvae are ingested by an intermediate host, such as a flea or a fish.
- Larvae develop into cysticercoids or cysticerci in the intermediate host.
- Definitive host ingests the intermediate host containing the larvae.
- Larvae attach to the intestinal wall of the definitive host and develop into adult tapeworms.
- Adult tapeworms produce eggs, which are passed in the feces to continue the life cycle.
3. Trematodes (flukes):
- Eggs are passed in the feces of infected individuals.
- Eggs hatch into miracidia in water.
- Miracidia infect a snail intermediate host.
- Miracidia develop into sporocysts, rediae, and cercariae within the snail.
- Cercariae are released from the snail and can infect a definitive host through penetration of the skin or ingestion.
- Cercariae develop into adult flukes in the definitive host, where they produce eggs to continue the life cycle.

1. Trematodes (Flatworms)
- Egg: Released into water, develops into a miracidium larva.
- Miracidium: Swims in water, penetrates an intermediate host (snail) and develops into a sporocyst.
- Sporocyst: Produces rediae larvae.
- Rediae: Leave the sporocyst, penetrate the snail's tissues, and produce cercariae larvae.
- Cercariae: Swim in water, attach to a definitive host (animal or human), and penetrate the skin.
- Juvenile: Migrates within the host's body to reach the final location.
2. Cestodes (Tapeworms)
- Egg: Released into the environment, contains an oncosphere larva.
- Oncosphere: Ingested by an intermediate host.
- Cysticercus (or hydatid cyst): Develops within the intermediate host's tissues.
- Definitive host: Ingests the cysticercus, which develops into an adult tapeworm in the intestine.
3. Nematodes (Roundworms)
- Egg: Laid by female worms, hatches into a first- or second-stage larva.
- Larvae: Develop in the environment or within an intermediate host.
- Infective larva: Enters the definitive host through ingestion, penetration, or inhalation.
- Adult: Resides in the host's digestive or respiratory system, producing eggs.
