EXPERIMENTS WITH HUMAN SUBJECTS 



105 



The ingestion of the very large numbers of B. biUgaricus brought 

 about no apparent change in the intestinal flora. It was impossible to 

 recover B. hulgaricus from the plates, which were free from colonies of 

 this general type except an occasional B. acidophilus colony. There 

 was no reduction whatever in the amount of gas production in the 

 Veillon tubes, and the Gram-stained slides were typical of the usual 

 flora of so-called "normal" individuals. The results are shown in 

 Tables 68a and 68b, and Chart 42a. These results are in accord with 

 those obtained with white rats, and fully corroborate the findings in the 

 B. hulgaricus milk feeding experiments on man.
