Figure 219. Microorganisms in Trichonympha. A, constantly present organism that 

 forms an aggregate surrounding or near to the nucleus of T. campanula; B, nuclear 

 parasite of T. saepiculae; C, Sphaerita in T. sphaerica; D, E, peg-formed organisms in 

 T. campanula; F, G, fusiform organisms in T. catnpanula; H, group of parasites (micro- 

 sporidia?) in T. magna; I, developmental stages of organism shown in H. (After Kirby, 

 1932a.) 



In early stages of invasion by the Nucleophaga-\ik.Q parasite, a body, 

 apparently amoeboid, is observed in the process of penetration into the 

 chromatin mass. In the earliest stages so far found, it is already multi- 

 nucleate. This becomes located in the interior of the chromatin mass, 

 and as it grows its nuclei multiply and the chromatin of the Trichonym- 

 pha nucleus becomes restricted to a peripheral reticulum (Fig. 220E).
