Hitherto the cultivation of protozoa has been successfulto a very limited degree. Kartulis (1891) claimed to have cultivatedAmoeba coli in an infusion of straw. He found however that multipli-cation did not occur, unless bacteria were present. Schardinger (1896)cultivated amoebae, in the presence of bacteria, on agar to which strawor hay infusion had been added. Tsujitani (1898), using Schardingersmethod, cultivated straw amoebae in the presence of various bacteria, S. cholerae, B. typhi.
