The genus Entamoeba was defined by Casagrandi and Barbagallo for the species Entamoeba coli, which is known to be a commensal organism. Lösch's organism was renamed Entamoeba histolytica by Fritz Schaudinn in 1903; he later died, in 1906, from a self-inflicted infection when studying this amoeba.

The genus Entamoeba was named in 1895 by Casagrandi and Barbagallo [ 3 ], who were studying E. coli , and for reasons that are unclear they (and others) concluded that Lösch’s ameba was the same organism.
Entamoeba are pseudopod-forming, protozoan parasites in the subphylum Sarcodina. The genus Entamoeba is composed of five species that infect humans: E. histolytica, E. dispar, E. hartmanni, E. coli, E. polecki and E. gingivalis. Only E. histolytica is known to cause disease in humans.
