PathogenThis section has been translated automatically.
- Dipylidium caninum (cestode, cucumber tapeworm).
- The adults are 10-70 cm long and 2-4 mm wide.
- The cestode parasitizes in the small intestine and consists of 200 tapeworm members (proglottids) and is of elliptical, cucumber-like shape.
- Released limbs migrate independently from the intestine.
- The egg packs are released when the limbs dry up. The eggs are taken up by flea species and mallophages. There the larva (oncosphere) hatches, which develops into the cysticercoid in the host. In the final host like cats, dogs and humans, they mature into adults.
- Infection e.g. through oral ingestion of fleas or contact with dog excrement or consumption of contaminated food.
