Entamoeba histolytica infection is a parasitic intestinal infection induced by the amoeba entamoeba histolytica, also known as E. histolytica. This protozoan passes the body when cysts are consumed in water or food. It can also enter the body via direct contact with feces.
The cysts are a latent type of parasite that can sustain in the soil or surroundings for a few months after being stored in feces. The microscopic cysts can be found in fertilizer, soil or water polluted with contaminated feces.
Cysts can be transmitted by food handlers while making preparations or handling food. It is also possible to transmit the virus during anal or oral sex and colonic irrigation. Cysts enter the body and become lodged in the digestive tract. They then emit a trophozoite, an intrusive, active form of the parasite.
