- Title:
- Electron Micrograph: Leishmania braziliensis promastigotes
- Description:
- This is an electron microscopic (EM) image of Leishmania braziliensis promastigotes grown in cell culture. Note the dense kinetoplasts in the cytoplasm of these flagellated forms.
Promastigotes are not found in human tissue; this stage occurs in the mid-gut of the sand fly (genera Phlebotomus and Lutzomyia) intermediate hosts. Promastigotes are elongate, slender and measure about 10-12 µm in length. They have a large central nucleus and a kinetoplast located near the anterior end. A flagellum arises at the anterior end, that may be longer than the rest of the promastigote.
