| Abstract: | In vitro agglutinability of trophozoites of threeEntamoeba histolytica strains, cultivated under axenic conditions in the presence of concanavalin A (Con A), was shown to be related to the degree of their pathogenicity for experimental animals and of the concentration of Con A. Seven strains ofE. invadens tested also agglutinated in the presence of Con A, and the degree of agglutination was proportional to the concentration of the lectin. Three strains ofE. histolytica-like  Laredo-type amebae, a strain ofE. terrapinae, and a strain ofE. moshkovskii agglutinated very slightly, only in the presence of the highest concentration of Con A tested. |
