Excerpt from Bacteria and Their Products This method (the maas method) is even now sometimes employed to obtain pure cultivations of cholera bacillus. A drop of the discharge from a cholera patient containing a large number of organisms besides the Specific cholera bacillus, when placed in broth which is so prepared as to be specially suited to the nourishment of the cholera organism, soon becomes almost a pure culture, as the cholera bacilli are able to multiply in an extraordinary degree at their optimum temperature and to far outnumber all the other organisms present, and it becomes a much easier matter to obtain from the broth culture a pure culture of the comma bacillus than directly from the cholera discharge itself. It may be said to correspond to the assing of a mixed culture through an animal. Certain organisms - those t at are pathogenic - can grow luxuriantly whilst the others make a much weaker struggle for existence.
