The parasite exists in two forms; an infective, non-dividing cyst stage and an actively dividing, invasive trophozoite. The dormant, non-motile cyst, upon ingestion by the host, gets converted to the actively dividing trophozoite in the colon.

The active (trophozoite) stage exists only in the host and in fresh loose feces; cysts survive outside the host in water, in soils, and on foods, especially under moist conditions on the latter. The infection can occur when a person puts anything into their mouth that has touched the feces of a person who is infected with E. histolytica, swallows something, such as water or food, that is contaminated with E. histolytica, or swallows E. histolytica cysts (eggs) picked up from contamin… Webb19 nov. 2024 · It is thought that, worldwide, about 40 to 50 million people infected with E. histolytica develop amoebic colitis or abscesses, causing up to 100,000 deaths per year.
