From: The phylogeography of trypanosomes from South American alligatorids and African crocodilids is consistent with the geological history of South American river basins and the transoceanic dispersal of Crocodylus at the Miocene

Figure 5

Microphotographs (light microscopy) of Giemsa-staining culture forms of Trypanosoma ralphi (a-d) and Trypanosoma terena (e-i). Cultures (~5 days) showing C- and roll-shaped large trypomastigotes with small kinetoplast and exuberant “undulant membrane” (a,e), transient forms between trypo- and epimastigotes (b,f), and small trypomastigotes (asterisk) (~7 days). Log-phase forms (c,g) showing rounded and long dividing forms (stars). The T. ralphi epimastigotes are pointed, exhibit a dilated anterior end (c), and the kinetoplast is thin and adjacent to the nucleus (c,d). The epimastigotes of T. terena are slender and the kinetoplast is rounded, and either very close or far from the nucleus (g,h); wider forms predominated in stationary cultures (h,i). Arrows indicate segments of the flagellar membrane detached from the cell body membrane. Nucleus (n), kinetoplast (k), flagellum (f).
