86 TRANSFORMATION OF THE INTESTINAL FLORA 



over the other intestinal organisms was maintained as long as the sour 

 milk consumption was continued. 



Similar results were obtained with subjects B, H, M, O and P, who 

 received one liter of the milk culture daily in addition to the ordinary 

 diet. The change in the intestinal flora of these individuals was quite 

 uniform, the ingestion of the acidophilus milk causing in each case such 

 a marked development of the B. acidophilus type as to overshadow 

 completely all of the other viable organisms ordinarily present. (See 

 Tables 53 to 57, and Charts 37 and 38.) It is of particular interest to 

 note that the dominating B. acidophilus flora of subjects H and O, who 

 received the milk cultures for twenty and thirty days respectively, 

 remained unchanged during the entire milk-feeding period, without any 

 apparent tendency whatever to revert to the original mixed flora. Fol- 

 lowing the discontinuance of the milk consumption the homogeneous
