- Trophozoite, or mobile form, is a uninucleated and pleomorphic structure, measures about 15-40 μm; the cyst measures 10-15 μm, and is a spherical tetranucleated structure covered by a chitin cell wall that confers its resistance to adverse conditions.

Feb 13, 2017 · Entamoeba histolytica occurs in the following forms, the trophozoites, precyst, cyst, metacyst, and metacystic trophozoite. The trophozoite is about 10–60 μm in size with a clear finely granular cytoplasm and a spherical nucleus that shows aggregation of chromatin beads at the nuclear membrane and a centrally located karyosome.

Mature Entamoeba histolytica/Entamoeba dispar cysts have 4 nuclei that characteristically have centrally-located karyosomes and fine, uniformly distributed peripheral chromatin. Cysts usually measure 12 to 15 µm.
May 8, 2012 · Venn diagram for 3-way comparison between the proteins of this study, proteins from the trophozoite proteome and the EST data on trophozoite. Overlaps between the E. histolytica cyst proteomic data (N = 417), trophozoite proteomic data (N = 1825), and the trophozoite specific EST data (N = 1223) were checked. A total of 191 proteins overlapped ...
