64 TRANSFORMATION OF THE INTESTINAL FLORA 



There appears to be a definite relation between the rate of absorption 

 or digestion in the alimentary canal of a utilizable carbohydrate and its 

 tendency to effect a transformation. Only those carbohydrates which 

 reach the caecum and colon unchanged have a transforming influence. 



The process of elimination of the ordinary mixed flora and the 

 establishment of B. acidophilus apparently does not depend on any 

 changes in the hydrogen ion concentration within the intestine.
