Jun 1, 2023 · What Is Endolimax Nana Cyst? Endolimax nana is an intestinal protozoan that thrives in the colon and has also been reported in the appendix. Dobell demonstrated that this infection might last for many years. Trophozoites feed primarily on bacteria and it grows through division by binary fission.
E. nana cysts can be identified and distinguished from other cysts by their smaller size (9 μm in greatest diameter; range, 5-14 μm, ovoid shape, and one to four vesicular nuclei, each usually containing a large, eccentric endosome). The nuclear envelope is very thin and is difficult to see even in stained preparations.
Endolimax nana cysts in concentrated wet mounts. Cysts of Endolimax nana are spherical to ellipsoidal in shape and measure 5 to 10 µm. Mature cysts possess four nuclei with large, karyosomes and no peripheral chromatin.
