by a heavy chromatin dot. The vacuole may at
times appear filled in. Pigment characteristically
forms early.
Developing Trophozoites. The key characteristic
of this morphologic form that distinguishes
it from the other Plasmodium species is the formation
of a nonameboid solid cytoplasm potentially
assuming a band, bar, oval, or roundish
shape (Fig. 6-5; Table 6-4). The cytoplasm consists
of coarse dark brown pigment often masking
