RHIZOPODA 407 



Whitmore 1 has carefully studied a number of cultures of amebae 

 obtained from cases of dysentery, one of them from a liver abscess, 

 and has concluded that in every instance the amebae were free- 

 living saprophytic forms belonging to the genus Amoeba and not 

 in any case parasitic species. 



Other Rhizopoda. The remaining orders of the Rhizopoda, 

 namely Helizoa, Foraminifer, Radiolaria and Mycetozoa contain 

 no parasitic forms of great importance to human pathology. 

 Plasmodium brassica which causes tumors on the roots of the 

 cauliflower plant is of some interest. 2
