    It forms cysts with four nuclei which excyst in the body and become trophozoites. Endolimax nana nuclei have a large endosome somewhat off-center and small amounts of visible chromatin or none at all. Cysts are small, with a spherical to ellipsoidal shape. Mature cysts contain four nuclei; immature cysts are rarely seen.

  2. Endolimax nana (Fig. 4-1) is the smallest of the intestine-dwelling amoebae infecting humans, its trophozoite averaging only 8 μm in diameter (range, 6-15 μm). The trophozoite lives in the host’s colon and is generally considered to be nonpathogenic.

  3. Jun 13, 2012 · Blastocystis hominis and Endolimax nana exist as two separate parasitic organisms; however co-infection with the two individual parasites has been well documented.

    Introduction . Endolimax nanais a small non-pathogenic amoeba with world wide distribution. Its life cycle is similar to that of E. histolyticabut is non invasive. Morphology of cysts . Cysts of E. nanaare 6 - 9 in diameter. They can be spherical or ovoid in shape and contain 4 pin-point nuclei which are highlighted by the addition of iodine.
