1906 H. M. Woodcock in Q. Jrnl. Microsc. Sci. 50 182 This is revealed..in the sharp resolution of the nuclear material into trophic and kinetic constituents, which are practically separate and independent, at any rate, during the trypanosome phase... The fertilisation spindle or definitive nucleus is to be regarded as representing the trophic portion, and it will be convenient, therefore, to distinguish it as the trophonucleus.
1928 L. E. H. Whitby Med. Bacteriol. xxi. 213 Stained preparations [of Trypanosoma gambiense] show two nuclear structures, the one, larger and centrally placed, is known as the macronucleus or trophonucleus.
