Hymenolepis diminuta treatment [19] was performed before and after treatment of Hymenolepis diminuta infected rats with different concentration of the plant extract. If diagnosed with dwarf tapeworm infection, a healthcare provider will treat you with praziquantel (the treatment of choice) or niclosamide or nitazoxanide (alternative drugs). diminuta ameliorates inflammatory diseases in many, but not all, animal models [20], and proved effective in the majority of self-treating humans surveyed in a recent study [18]. Given egg similarity, care is needed in diagnosis to prevent confusion with the closely related and Hymenolepis diminuta is primarily a rodent parasite that is ubiquitously distributed worldwide, but with only a few cases described as human infections. diminuta, the rat tapeworm, has a life cycle similar to the indirect cycle of Hymenolepis nana in grain insects. diminuta, the rat tapeworm, has a life cycle similar to the indirect cycle of Hymenolepis nana Hymenolepis nana (Dwarf Tapeworm) Infection Hymenolepis nana, a tiny intestinal tapeworm, is one of the most common human cestodes; the life cycle does not require an intermediate host. diminuta infection.

Despite the fact that the adult tapeworm does not possess clinging organs (hooks) that could damage host tissues, its metabolites can affect the proper functioning of a host’s digestive tract []. However, considering the patient's neurological disease, we decided to use not praziquantel but niclosamide, which proved equally effective.
