Effects of Some Environmental Factors upon Growth and Encystation of Entamoeba invadens

Abstract

The life cycles of Entamoeba and most other parasitic amoebae are marked by an alternation of trophic growth and asexual multiplication with the periodic formation of resistant cysts. A true understanding of the biology of intestinal amoebae, establishing a rational basis for control of amoebiasis, requires studies of both trophic growth and encystation. The former represents the road to pathogenesis, while the latter process involves a distinctive series of metabolic events
