TAXONOMIC SEROLOGY OF AMOEBA PROTEUS 121 between strains AP and TiP were in strain AP because of the following reasons: (a) strain AP differed significantly from all strains of A. proteus, with the exception of its cytoplasmic hybrid, I~Pc, in G + C content of the denser nuclear DNA band, whereas strain TIP had the same G + C content as the other strains of A. proteus [9]; (b) strain … Contents. There are numerous parasitic amoebas. There are many species, of which the most extensively studied is Amoeba proteus.
