Summary
Experiments were performed with the cultures ofProteus vulgaris andBacillus pyocyaneus, the initial strains of which did not posses natural antitumor properties.
These bacteria were cultured for a long period in a medium in which Crocker's sarcoma cells formed the source of nutritive substances. This resulted in the appearance of certain substances among the metabolites of the bacteria able to selectively depress the development and the growth of Crocker's sarcoma in mice.
