72 INFECTIONS OF THE DIGESTIVE TRACT 



in the faeces. Indol and phenol are found in the faeces 

 in only very small quantities a few milligrams in 

 one hundred grams of the moist faeces. Frequently, 

 indeed, only a trace of indol is detectable in the intestinal 

 contents. The character of the urine as regards putre- 

 factive products corresponds to the faeces. The ethereal 

 sulphates are low in proportion to the preformed, and 

 there is little or no indican in the urine. There is also 

 little phenol. The reaction with dime thy lamidobenz- 

 aldehyde is slight or moderate. Frequently it is so 

 slight that its existence is questionable. During a 

 period of temporary digestive derangement the ethereal 

 sulphates may show a considerable increase, and indican 

 may be present, but as the derangement subsides the 

 urinary indications of putrefactive decomposition in 

 the intestine likewise grow less and gradually fall back 

 to the previously existing normal level. 



Period of Adult Life. During adult life factors 

 usually enter into the lives of human beings which are 

 not without influence upon the bacterial conditions 

 that prevail in the stomach and intestine. Great 

 differences exist in the habits of different persons at 

 this time of life, and these differences are in a degree 

 reflected hi the nature of the bacterial processes that 



as are also slender, negative bacilli. There are moderate numbers 

 of positive diplococci and diplobacilli. Organisms of the capsulatus 

 type are a little more numerous than at the last level. There are 

 a very few free, oval spores, and a few spore-holding bacilli, very 

 much enlarged, suggesting clostridia. There are also some few 

 slender Gram-positive bacilli about the length of B. aerogenes 

 capsidatas or longer, but about one-half the diameter of capsulatus.
