TRICERCOMONAS INTESTINALIS 



Wassell (1921) as E. sinensis, but it seems probable that 

 the specimens observed belonged to the species already 

 known. 



(3). TRICERCOMONAS INTESTINALIS 



This flagellate (Fig. 12a, 12b) has been reported in 

 less than 100 cases. It appears in the feces in both the 

 trophozoite and cyst stages. Nothing is known regarding 

 its relations to the human host. Much confusion exists 

 regarding this species and Enter omonas hominis (Fig. 

 14) described by Fonseca (1915) ; the reader is referred 

 to Wenyon ( 1926) for a discussion of this subject.
