210 THE ANIMAL PARASITES OF MAN 



4. The body next breaks up into a number of smaller bodies 

 known as initial corpuscles. These, in their turn, divide by simple 

 division (in the manner already described) into numerous elementary 

 bodies (fig. 119). Thus, the life-cycle is completed. 



The Chlamydozoa are, then, the minute granules inside the body of 

 the Cytoryctes variolce or the Nenroryctes liydrophobice, so that the whole 

 body of the Cytoryctes or Xcuroryctcs corresponds to the mantle and 

 parasite of the Chlamydozoon. The Cytoryctes group is said to 

 cause destruction of the host cell. The Cytooikon group (e.g., 

 trachoma bodies) causes proliferation of the host cell. 



In September, 1913, Noguchi : described the cultivation of the 

 parasite of rabies in an artificial medium, similar to that used by.<him 

 for the cultivation of Spirochctta recurrent is. The cultures were stated 

 to HP infprtivp to HOCK rabbits and Puinea-Di^s. Levaditi, in 



Sergentella hominis, Brumpt, 1910. 



Et. and Ed. Sergent in 1908 found vermiform bodies about 40 //, 

 long by i /* to i'5 /* broad in the blood of an Algerian suffering from 

 nausea and cold sw r eats, without other symptoms. The bodies were 

 pointed at each end, with a somewhat ill-defined nucleus in the 

 middle. Their systematic position is doubtful.
