The biochemistry and cell biology of "Leishmania" is similar to that of other kinetoplastids.They share the same main morphological features, including a single flagellum which has an invagination, the flagellar pocket, at its base, a kinetoplast, which is found in the single mitochondrion, and a subpelicular array of microtubules, which make up the main part of the cytoskeleton.
