Abstract

SUMMARY: Aqueous extracts of sp. and have been found to cause excystment of viable sterile cysts of The factors which cause excystment are thermostable. With the aid of paper partition chromatography of the aqueous extract of sp., it has been found that part of the excystment-inducing activity is due to the presence of amino acids, some of which have been identified. Amino acids, sugars, purines, pyrimidines, nucleosides, nucleotides and organic phosphates have been tested for their ability to induce excystment. It has been found that some amino acids and a few nucleotides can cause excystment. The effect of pH, concentration and time on excystment with amino acids has been studied.
