Figure 10. Rapid switching between synchronised and chaotic motion inside the ectoperitrophic space of the tsetse fly midgut.
Infected tsetse fly midguts were dissected and analysed in PBS. Swarms of trypanosomes in the long procyclic to mesocyclic transition stages were recorded with 250 fps in the ectoperitrophic space of the anterior midgut (Video 10). Scale bars: 10 µm. (A) Switch from chaotic (left panel) to synchronised motion (right panel). (B) Synchronised motion (left panel) of cells and transition to chaotic movement (right panel) within a few seconds. Fluorescent trypanosomes express GFP in the nucleus and/or the flagellum.
