When again placed under favorable conditions of moisture, temperature, food supply, etc.,the spore germinates into a bacillus and the process of reproductionby fission recommences. Bacteria absorb nourishment through theexternal surface of the cell from the surrounding materials, thesebeing acted on as a preparation for absorption by ferments secretedby the cell. Bacteria thus digest their food outside the cell body, aprocess which results in chemical changes in the matter surround-ing them; changes made evident in the various processes of fer-mentation, putrefaction and decomposition of organic substancesresulting from the action of saphrophytic bacteria, and in thecase of the disease-producing or pathogenic species, in injuryor destruction of the tissue cells of higher organisms invaded bythem. Abundant moisture is essential for bacterial growth. The. Fig. 4.—Diphtheria bacilli. (Microphoto-graph by Carr.) Fig. 5. — Spirilli of Asiaticcholera (Carr). CELLS OF BODY AND INVADING CELLS
