Leishmania sp. amastigotes
Amastigotes are the most commonly-seen form of Leishmania species in humans. These non-motile forms of the parasite are round-to-oval, measure 2-4 micrometers in diameter, and have a small nucleus and rod-shaped kinetoplast (see accompanying schematic). They reside within phagocytic cells such as macrophages as seen here on this Giemsa-stained air-dried touch preparation.
