B. coli lives and grows in the intestinal tract of man and mam- mals, and organisms closely resembling it have been found in the intestinal canal of other vertebrates. It is discharged in large ' For the organisms of the colon-typhoid-dysentery group the Committee of the Society of American Bacteriologists has adopted the generic name Bacterium Ehrenberg 1838, emended Jensen, 1909. Its use in this sense may lead to con- fusion with the genus Bacterium Migula, especially in the minds of beginning students. The old generic name. Bacillus, is therefore here retained. 22 ,337.
