Electrophoretic isoenzyme patterns of Entamoeba histolytica and Entamoeba coli

Abstract

Cultures of 14 stocks of Entamoeba histolytica and one only of Entamoeba coli were compared by electrophoretic patterns of three enzymes: glucose-phosphate isomerase, phosphoglucomutase and L-malate: NADP+ oxidoreductase (oxaloacetate-decarboxylating). Easily distinguished patterns divided E. histolytica into three groups, whilst a distinctly different pattern for E. coli was also seen.
