AMCEBA COLL 647 



Concerning the source of the amoeba and the mode of 

 infection little can be' positively stated. It is reason- 

 able to suppose, however, that the mouth must be the 

 usual path of infection, and that the amoeba, in all 

 probability, is taken with drinking water. 



With regard to other organisms found in amoebic 

 dysentery, a great number of bacteria of various kinds 

 and some flagellated infusorial organisms are associated 

 with the amoeba in dysenteric stools.
