Clockwise from top right: Amoeba proteus, Actinophrys sol, Acanthamoeba sp., Nuclearia thermophila., Euglypha acanthophora, neutrophil ingesting bacteria. An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability ...
An amoeba of the genus Mayorella (Amoebozoa, Discosea). Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm.
Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.

Entamoeba is a genus of Amoebozoa found as internal parasites or commensals of animals. In 1875, Fedor Lösch described the first proven case of amoebic dysentery in St. Petersburg, Russia. He referred to the amoeba he observed microscopically as Amoeba coli ; however, it is not clear whether he was using this as a descriptive term or intended ...

A representation of the endosymbiotic theory. An endosymbiont or endobiont [1] is an organism that lives within the body or cells of another organism. Typically the two organisms are in a mutualistic relationship.
Cysts of Entamoeba can survive for up to a month in soil or for up to 45 minutes under fingernails. [2] Invasion of the intestinal lining results in bloody diarrhea. [2] If the parasite reaches the bloodstream it can spread through the body, most frequently ending up in the liver where it can cause amoebic liver abscesses. [2]
Even with treatment, CNS infection with Acanthamoeba is often fatal, and there are very few recorded survivors, almost all of whom had permanent neurocognitive deficits. [17] The prognosis is largely influenced by the time of diagnosis, how virulent and sensitive the Acanthamoeba strain is, and, most crucially, the immune status of the affected ...
