The antigenic anatomy of Entamoeba histolytica and the variation in response of 148 patients with amebic disease are described. Immunoelectrophoretic patterns and indirect hemagglutination titers were studied in sera obtained from patients with amebic disease acquired in several areas of the world, i.e., Canada, Vietnam, Africa, India, Central America, and southern United States. The various populations are compared and similarities and differences are discussed.
