Trypanosoma lewisi Kent is a nonpathogenic hemoflagellate of rats (Rattus spp.). After briefly reviewing its infrastructure, the writers postulate that inside the flagellum the change in shape of kinetosomal plate 1 may cause one of the central microtubules and the helical-like structure to contribute to flagellar movement. The energy to run this system may be transferred from the kinetoplast with its associated mitochondrion.
