In 1911, Sistrunk1 published our earlier experience at the Mayo Clinic with regard to the finding of intestinal parasites in individuals residing in the middle Northwest. Since then the examination of the stools in certain cases has led so frequently to the identification of entamebas that we have come to consider this infection as a relatively common one. In the diagnosis of the different types of amebas present, Craig's2 description of the morphologic characteristics has been followed in our laboratories by Sistrunk and Sanford. Moreover, the recent work of Darling3 and Craig4 on the identity of Entamoeba tetragena with Entamoeba histolytica inclines us to prefer to group eases in which a morphologic diagnosis of either one of these parasites was made as Entamoeba histolytica. In this review, however, the former distinctions between tetragena and histolytica are maintained because of any interest that may remain in connection
