Hymenolepiasis is the most common intestinal tapeworm infection of humans caused by worm of family cestoda, genus Hymenolepis and species nana. This infection does not require an intermediate host and infection can occur directly from one infected person to another by fecal-oral transmission.
Why is H Nana called dwarf tapeworm?
Infection with the dwarf tapeworm (so-called because of its small size) Hymenolepis nana occurs worldwide, mostly in children living in conditions with poor sanitation.
What is the difference between H Nana and H. diminuta?
diminuta tapeworm is much larger than H. nana and measures 10 to 60 cm long and 2 to 4 mm wide. Completion of the life cycle of H. diminuta depends on development of the cysticercoid stage in the body cavities of insects that ingest eggs they find in rodent feces; autoinfection does not occur.
What are the typical symptoms of H nana infection?

Less frequent, but more serious cases of paragonimiasis occur when the parasite travels to the central nervous system.
What causes Nana?
Hymenolepiasis is caused by two cestodes (tapeworm) species, Hymenolepis nana (the dwarf tapeworm, adults measuring 15 to 40 mm in length) and Hymenolepis diminuta (rat tapeworm, adults measuring 20 to 60 cm in length).

How is Diphyllobothriasis presented?
Most humans with diphyllobothriasis (all forms) are asymptomatic, and the most common presentation is passage of worm parts, which can be alarming. Many patients retrospectively report diarrhea or may present with symptoms of obstruction or even appendicitis.
Does eating crustaceans cause Diphyllobothriasis?
The tapeworm causing diphyllobothriasis (Diphyllobothrium latum) is widespread in North American freshwater fish, passing from crustacean to fish to humans by consumption of raw freshwater fish. It is especially common among Inuit peoples and may be asymptomatic or cause severe general and abdominal disorders.
What are the typical symptoms of H. nana infection?
How do you control Paragonimiasis?

What is the cause of Hymenolepis nana in humans?
Hymenolepiasis is primarily caused by the cestode (tapeworm) species, Hymenolepis nana (the dwarf tapeworm, adults measuring 15 to 40 mm in length). Eggs of Hymenolepis nana are immediately infective when passed with the stool and cannot survive more than 10 days in the external environment .

A morphologically identical variant, H. nana var. fraterna, infects rodents and uses arthropods as intermediate hosts. When eggs are ingested (in contaminated food or water or from hands contaminated with feces), the oncospheres contained in the eggs are released.
Which is phase of H nana life cycle is most susceptible?
Research has shown that the cysticercoid phase of H.nana’s life cycle is the most susceptible to the Praziquantel treatment. In 1980, research proved that Praziquantel had morphological effects on H.nana and other similar cestodes.
