| Hymenolepis nana | The dwarf or dwarf mouse tapeworm; a small tapeworm of man, sometimes found in great numbers in the intestine; the cysticercoid can develop by two pathways: in the final host, with the egg from one human directly infective to another human host, in which both larval and adult stages occur, or through two hosts, an insect (or crustacean) intermediate and a vertebrate final host, the obligate two-host cycle of most cyclophylidean cestodes; in addition, Hymenolepis nana can internally reinfect the same human or rodent host, producing a massive reinfection.

| Hymenolepis nana fraterna | A race, strain, or subspecies of Hymenolepis nana adapted to mice, although infectivity to humans may remain; the human form, Hymenolepis nana, presumably is derived from the rodent strain. (05 Mar 2000) |
