   Entamoeba coli, E. hartmanni, E. polecki, Endolimax nana, and Iodamoeba buetschlii are generally considered nonpathogenic and reside in the lumen of the large intestine in the human host. Both cysts and trophozoites of these species are passed in stool and are considered diagnostic .

   Nov 4, 2015 · The cysts of Endolimax and E. hartmanni both have four nuclei but can be differentiated by E. nana having a larger punctuate karyosome and peripheral chromatin, both of which features however may be quite difficult to discern. [ 8, 47] Endolimax stains with both Ziehl–Neelsen and trichrome.

   What is Endolimax nana?

   • 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. According to some surveys, prevalence may be as high as 30% in some populations.

   How do you smear Endolimax nana cysts?

   • Cysts of Endolimax nana in direct smear (a), concentrated with formalin and ethyl acetate and stained with iodine showing the characteristic gibbous appearance (b), and isolated on a sucrose gradient and stained with iodine, respectively (c).

   What does Endolimax look like?

   • When mature, cysts of Endolimax are oval and very small (6–9 μm × 5–7 μm) compared with cysts of other intestinal amebae. The cyst wall appears thin (80 nm), colorless, and smooth on the outside. In the cytoplasm, no mitochondria, Golgi apparatus, rough endoplasmic reticulum, centrioles, or microtubules are present.

   How is Endolimax diagnosed?

   • The diagnosis of Endolimax traditionally relies on microscopy of cysts, which can be direct or coupled with a concentration procedure and different stains prior to analysis. Concentration can be formalin-based [ Figure 1a ], and when the fecal concentrate is stained with iodine, cysts of E. nana appear gibbous [ 7] [ Figure 1b ].

   Jun 13, 2012 · Stool specimens are examined through light microscopy by direct wet mount, trichrome stains and formal-ethyl acetate concentration. Infectivity is classified by identification and quantification of B. hominis cysts and E. nana cysts and trophozoites present in stool specimens [ 1, 16, 17, 18 ].

   The resulting slide-level agreement for positive specimens was 98.88% (95% confidence interval [CI], 93.76% to 99.98%). The one slide reported as negative was manually examined by microscopy, and the target organism ( Endolimax nana) was detected.
