This stage is diagnostic. These plasmodia are also
motile. The cells in the background are host
granulocytes.
Schizogony of the plasmodium. The filamentous trophont can divide
via budding to produce more plasmodia, or via schizogony to produce
trophonts. The mass of cells in the center of the field represents the schizont.
