SYNOPSIS. Growth curves in a monophasic, polyxenic medium are presented for a strain of Entamoeba invadens. Three characteristics of these curves are: 1) the increase in numbers of trophozoites is linear with time; 2) the increase in numbers of cysts is linear with time; and 3) the durations of these 2 periods are equal to each other. Additional experiments are described in which variations of the culture conditions do not alter these 3 characteristics. Because of these data, we propose that, under the cultural conditions we have used, division of the trophozoites of Entamoeba invadens is coupled to the differentiation of these cells into cysts.
