Cassedebat isolated three species of bacilli from water, which could be distinguished with great diiBculty, and only after the most â careful comparison. The bacillus which most â closely resembles it is the Bacillus coli com- munis ; in fact, Ptoux regards it as a non- pathogenic variety of the typhoid bacillus. Others claim to be able to distinguish it by careful comparison and the application of tests. Special importance is attached to potato cultures, the typhoid bacillus forming an invisible film, and Bacillus coli communis a well-marked yellowish growth. Terni pointed out that Bacillus typhosus retains its motility in media containing hydrochloric acid, while Bacillus coli communis and other.
