Visualization of distinct forms of T. cruzi during metacyclogenesis. Images of T. cruzi during metacyclogenesis, showing the position of the nucleus (N) and the kinetoplast (K). The nucleus is localized centrally and becomes more elongated from the epimastigote to the trypomastigote stages. The flagellum and kinetoplast are repositioned from the anterior to the posterior region of the cell body along metacyclogenesis. Five forms were observed: epimastigote, intermediate I, intermediate II, intermediate III, and trypomastigote. Scale-bars: 10 μm
