WebHymenolepis nana is an auto-infecting parasite that does not require an intermediate host. It can, however, grow in rats as well. The fertilized eggs pass in the stool from an infected host. The eggs are then either eaten by an insect or by a human which mainly occurs through the ingestion of contaminated food or water. WebEggs of H. nana are ovoid, measuring 30–47 μm in diameter and have a thin, hyaline shell. The oncosphere has six hooklets and is surrounded by a membrane with bipolar thickenings.
