It forms gas. In agar it forms round colonies and sporalates abundantly, 

 but in saccharated media does not spore at all. It forms acid in saccha- 

 rated media, coagulates milk, forms indol, and is not pathogenic to 

 laboratory animals. 



Properties of Bacillus tuberculosis cultivated on Bile.* — H. 

 Calmette and C. Guerin found that when Bacillus tuberculosis of bovine 

 origin is cultivated on bile it easily passes through the wall, of the 

 alimentary canal, and when it penetrates in large masses it may rapidly 

 produce calcareous nodules. When injected intravenously into Bovines 

 it produces a general febrile disorder without the formation of tubercles, 

 a typho-bacillosis in fact. On bile medium human tubercle grows with 

 difficulty, avian tubercle not at all, and per contra, each of these tuber- 

 culoses when cultivated on human or avian bile develops very rapidly.
