Trypanosoma rangeli: ultrastructure and activity of the mitochondrion

Abstract:
Axenic cultures of pure Trypanosoma rangeli were used to investigate the relation between ultrastructure and activity in the mitochondrion. Every other day, ultrathin sections were obtained from cultivated flagellates and, subsequently, observed in order to register changes in the cytoarchitecture of the organelle. Culture samples were incubated in tetrazolium salts to determine the mitochondrion's metabolic state. The results show a high correspondence between mitochondrion ultrastructural shape and function of the same organelle in populations of T. rangeli maintained under in vitro conditions.
