Entamoeba histolytica

The Entamoeba histolytica is a species of protozoan, which is parasitic and pathogenic to man. Once it has entered the human body, the Entamoeba histolytica lives in the large intestine, attacking its mucosa and causing amebic dysentery and lesions that can perforate the walls of the intestine. The active phase of the E histolytica is called trophozoite, which measures between 20 and 40 microns. It has pseudopod, which is formed from its ectoplasm. The parasite can end up in the liver, being transported in the blood flow of the portal vein, and cause hepatic amebiasis. It can also attack the lungs and brain.
