Research output: Contribution to journalArticle


The growth of Tetrahymena was influenced by both diphtheria and tetanus toxoids; depression occurred at a high and stimulation at a low concentration. Pretreatment with the stimulating concentration of diphtheria toxoid caused a lasting modification of growth rate and development of imprinting that resulted in an enhanced response of the cell at reexposure to the toxoid. Tetanus toxoid failed to induce either switch over of cell function or imprinting.
