Normally in mice the intra-villus phase of Hymenolepis nana life cycle is completed by the fifth day of infection. However, when the mice were fed continuously on a mixture of 1.5 g Telmin (166.7 mg of mebendazole/g) per kg of food (Purina Lab Chow) from day 1 (24 h) post ...
Life cycle of Hymenolepis nana. Credit: Image courtesy of Gino Barzizza. Due to certain physiological variations, many authorities recognize two subspecies of H. nana: H. nana nana, which infects humans, and H. nana fraterna, which infects rodents. The life cycle of the rodent subspecies ...
prolifrate you can find proglottids or eggs in the feces and if eaten by another person the life cycle will continue you may get : some eggs instead of being pass through feces outside , they will release their oncosphere and go to the villi so this is really an exception where the ...
H. nana is the only cestode without any intermediate hosts in itslife cycle [11]. H. nana infection is typically acquired from eggs in the feces fromanother infected individual, which are transferred by contaminated food. Eggs hatch inthe duodenum, releasing oncospheres that penetrate the mucosa...

Some aspects of histological alteration in the tapeworm Hymenolepis nana infected white mice by transmission electron microscopy This transmission electron microscopy (TEM) study has shown that the all of sections were obtained from tapeworm, Hymenolepis nana infection which were administered by eggs to...
Hymenolepis nana, the last-to-be-described human tapeworm of Class Cyclophyllidea, has a complex life cycle that can only be understood in terms of its ability to combine the primary and secondary phases of its life cycle within a single host organism. Hymenolepis nana, the dwarf tapeworm ...
nana. The requirement of an arthropod intermediate host in the life cycle of H. diminuta (Wardle and McLeod, 1952) undoubtedly has limited its incidence in laboratory mice where good management practices are observed. Differentiation from H. nana can be done on the basis of the size of the ...
The life cycle may be direct or indirect (R. nanais the only cestode known that does not require an intermediate host). The indirect cycle utilizes arthropods as intermediate hosts. Liberated oncospheres penetrate intestinal villi and develop into a cercocystis stage before reemerging into the ...
nana is zoonotic and can have a direct life-cycle, whereas H. diminuta always has an indirect life-cycle, utilizing an intermediate host, and is not zoonotic. Although not uncommon in wild rats (Easterbrook et al., 2008), both are rare in laboratory rats (Livingston and Riley, 2003). ...
