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.
