This is an electron microscopic (EM) image of Leishmania major amastigotes grown in cell culture. Note the dense kinetoplasts in the cytoplasm.
Additional Information:
“Amastigotes of Leishmania are spherical to ovoid and measure 1-5 µm long by 1-2 µm wide. They possess a large nucleus, a prominent kinetoplast, and a short axoneme, the last of which is rarely visible by light microscopy. The organisms reside in macrophages of the host and can be found throughout the body.”
