Shape-shifting trypanosomes: Flagellar shortening followed by asymmetric division in Trypanosoma congolense from the tsetse proventriculus
Fig 10
SEM images of proventricular cells of T. congolense 1/148 during first cell division. (A) The posterior-to-posterior conformation with a narrow cytoplasmic bridge connecting the two trypanosomes (arrowed); both cells appear to be trypomastigotes, judging by the exit position of the flagellum, rather than a proventricular cell and daughter; scale bar = 2 μm. (B) Proventricular trypanosome with daughter cell (top) joined by a cytoplasmic bridge between the posterior of the mother cell and the mid-region of the daughter; judging by the length of the free flagellum of the daughter, these two cells are about to separate; scale bar = 2 μm. (C) Close up of the cytoplasmic bridge; scale bar = 1 μm. (D) Proventricular trypanosome with daughter cell (bottom) joined by a cytoplasmic bridge between the posterior of the mother cell and the mid-region of the daughter; scale bar = 2 μm. (E) Close up of the cytoplasmic bridge; scale bar = 1 μm.
