MALARIA 



93 



The change of form and position of the parasite in the corpuscle 

 from time to time. 



That it pushes out and retracts pseudopodia. 



The movement is suspended when the concentration of haemozoin 

 is accomplished. 



The haemozoin particles are finer than cjuartan and have more active 

 and incessant movement. 



There is hypertrophy and marked decolorization of the invaded red 

 cell, which may be twice its normal size. 



The rim of haemoglobin becomes almost colourless. 



With deep Leishman's stain the Hb. shows chromatophile dots, 



Simple benign tertian. 



" Schiifner's " dots, which are not shown by quartan or sub-tertian 

 parasites. 



The segmented body has sixteen to twenty spherules, like a cluster 

 of grapes and not daisy fashion. One or two particles of pigment 

 can be seen among the spherules. These latter are smaller, smoother 

 and rounder than those of the quartan, 



The segmented parasite is called a " rosette " body. 



As in the quartan the gametocyte is a spherical body, but much 

 larger than the quartan. 



This parasite is the commonest, and occurs in tropical and tem- 

 perate climates. 



The fever resembles that of the quartan type. 



Spontaneous cure is more likely than in the quartan type. 



The resulting anaemia is more readily recovered from than that of 

 quartan malaria. 



Double Benign Tertian Fever. 



This is the same as the above, but there are two families of 

 parasites maturing on different days. The two attacks may not be 

 equal in severity.
