Trophozoites of Entamoeba coli usually measure 15–50 µm. The trophozoites have a single nucleus with a characteristically large, eccentric karyosome and coarse, irregular peripheral chromatin. The cytoplasm is usually coarsely granular and vacuolated (often described as “dirty” cytoplasm).

Aug 23, 2023 · Entamoeba coli, similar to other Entamoeba specifies, has three distinct morphological forms: trophozoite, pre-cystic stage, and cystic stage. The trophozoite form, which measures 20 to 25 μm, is minimally mobile. [23]

Table 1: Characteristics of Intestinal Amebae Visible in Different Types of Fecal Preparations. Quensel’s stain may be substituted for buffered methylene blue. Nuclei of trophozoites are visible in formalin-fixed material but are usually not sufficiently distinctive for species identification.

Aug 23, 2023 · Entamoeba coli is one of many non-pathogenic protozoa found in humans. [1] . It is transmitted through fecal-oral contact, and the mature cyst can be found in contaminated water. [2] . Typically, these protozoa inhabit the large intestinal tract and can be identified in diagnostic stool specimens. [3] .

How do you identify Entamoeba coli?
What type of chromatin does Entamoeba coli have?
Structure. The trophozoite is 10 to 60 µm in diameter, ameboid, actively motile, and often erythrophagocytic. In stained specimens, the nucleus has a central karyosome with finely beaded peripheral chromatin. The cyst form is rounded, 10 to 20 µm in diameter, with one to four nuclei showing the characteristic appearance.
