Abstract

Summary: Axenically prepared cysts of readily excysted in the presence of heat stable factors prepared from and several fungi. Peptone, proteose peptone, tryptone or amino acids also promoted excystment. Crowding of the cysts and dilution of bacterial extracts adversely affected the excystment. Continual presence of the factors in the medium was essential for excystment.
