Endolimax is a genus of amoebozoa that are found in the intestines of various animals, including the species E. nana found in humans. Originally thought to be non-pathogenic, studies suggest it can cause intermittent or chronic diarrhea.
Figure E: Mature cyst of E. coli stained with trichrome. This figure and Figure F display the same cyst in two different focal planes, showing eight nuclei in total. Also, above the cyst in this figure, a trophozoite of Endolimax nana can be seen.
a. Endolimax nana, Giardia lamblia, and Entamoeba coli b. Giardia lamblia, Dientamoeba fragilis, and Cryptosporidium parvum c. Cryptosporidium parvum, Trichomonas vaginalis, and Entamoeba coli d. Trichomonas hominis, Dientamoeba fragilis, and Endolimax nana
Dientamoeba fragilis is a flagellate that lacks external flagella and therefore must be morphologically differentiated from the small nonpathogenic amebae (e.g., Endolimax nana, Entamoeba hartmanni). Dientamoeba fragilis trophozoites measure 5 to 15 µm; cyst-like stages are rare. Pseudopodia are angular to broad-lobed and transparent.
Endolimax nana and; Iodamoeba butschlii. Except for Dientamoeba, the parasites above are not thought to cause disease. Free living amoebas. These species are often described as "opportunistic free-living amoebas" as human infection is not an obligate part of their life cycle. Naegleria fowleri, which causes primary amoebic meningoencephalitis
