“…These would account for the virulence of such particles. On the other hand Spengler's "splitters" (14), the work of Sweany (15) and especially the recent single cell studies of Kahn (16) would suggest that they may be stages in the development cycle of the microorganism.…”

“…The extensive literature of the past 20 years on the growth of tubercle bacilli may well be considered in connection with how much light it throws on the life cycle of these organisms. It has been analyzed recently by LShnis (26), Sweany (27), and Kahn (28,29). The most extensive bibliography is the recent list of 462 articles by Puntoni (30).…”

The Induced Development of Non-Acid-Fast Forms of Bacillus Tuberculosis and Other Myco-Bacteria

In a previous communication (1), a description was given of an organism which was obtained from a stock culture of human tubercle bacilli, Strain H-37. This organism had the morphological characteristics of the parent strain but its growth was more rapid, and it was chromogenic, having acquired a deep yellow-orange color. On media suitable to acid-fast growth, colonies of this organism were made up of non-acid-fast rods with a scattering of acid-fast granules and rods. On more simple media, the acid-fast elements were almost entirely absent. This organism caused tuberculosis in three of five guinea pigs. It was assumed to be a non-acid-fast type of B. tuberculosis and was named the chromogenic H-37 strain.The work represented in the present communication was done in order to determine whether there existed in association with the chromogenic H-37 strain an agent causing the loss of acid-fastness and, if this agent was transferable, to use it in degrading acid-fast organisms into non-acid-fast forms.Extracts of the chromogenic H-37 organism were made and passed through a Berkefeld filter and added to the culture media on which six strains, representing four types of mycobacteria, were grown. From five of the six strains, growths which were apparently wholly non-acid-fast were obtained; the sixth strain, an organism recently isolated from human renal tuberculosis, developed non-acid-fast
