The trophozoite stage of Entamoeba histolytica is the active, feeding stage of the parasite. It is
characterized by a single nucleus and large cytoplasm that contains several vesicle and granules.
The trophozoite is usually pear shaped and measures approximately 10-60 micrometres in length.
After the trophozoite are released then they travel through the intestine, where they feed on
bacteria and other microorganisms. They can also invade the intestinal wall and cause tissue
damage, leading to symptoms such as diarrhoea, abdominal pain, and bloody stools. Some
trophozoite may also enter the bloodstream and migrate to other organs such as the liver here
they can cause abscesses. This is known as extraintestinal amoebiasis. After several days, the
trophozoite begin to encyst in the large intestine. Encystation is the process by which the
trophozoites transform into dominant cyst stage, which is resistant to environmental stresses such
as desiccation and temperature change.
