BAGILLTJS CO LI COMMUNIS. 445 Escherich, to degenerative changes in the protoplasm. The colon bacillus does not form spores. There is nothing in the morphology of this bacillus which is characteristic or which may aid in its identification, for in this respect it simulates many other organisms. Fig. Colon bacilli.

It is an aerobic, facultative anaerobic, non- liquefying bacillus. It is motile, but its movements are so sluggish that a positive opinion is often difficult, being exhibited often by one or two individuals, in fresh cultures, and at a high temperature only. These move- ments are produced by flagella, which may be demon- strated by Loffler's method of staining, though not usually in such numbers as are seen to occur on the bacillus Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Park, William Hallock, 1863-1939; Guerard, Arthur Rose, 1851-.
