cysts lining gut

A disease caused by infection with the protozoan parasite entamoeba histolytica, acquired by ingestion of food or water contaminated with faeces containing infected cysts. Once inside the gut, the cysts hatch to release the adult organisms, which irritate the gut lining resulting in severe bloody diarrhoea. They also invade the lining to enter the blood stream, and circulate throughout the body forming cysts in the liver, lungs, and brain.
