OTHER INTESTINAL TRICHOMONADS. 



Derrieu and Raynaud (1914), Chatterjee (1915), 

 Haughwout and deLeon (1919), and Kofoid and 

 Swezy (1924) have called particular attention to a 

 subgenus of Trichomonas carrying five anterior flag- 

 ella instead of four. From time to time trichomonads 

 of man have been described without the regulation 

 number of flagella. Kofoid and Swezy (1923) name 

 the five flagellated organism, Pentatrichomonas, the 

 specific name for that of man being P. ardin delteili, 

 and the three flagellated form Tritrichomonas. 



Pentatrichomonas in man is given special signifi- 

 cance by some of these writers on account of finding 

 it in cases of dysentery and also its habit of ingest- 

 ing red blood corpuscles. Kofoid and Swezy have 

 cultivated the organism and determined its survi- 

 val in rain, tap and creek water for three days.
