Identification of Leishmania donovani /CC6-P (B.SC.ZOOLOGY_MAJOR_CCF)

Identifying features are:

1. Elongated, spindle shaped body.
2. Size 10-20µm in length and 1-5 µm in width.
3. Flagellum is present at its anterior end helps in movement.
4. Kinetoplast, a dense granule of mitochondrial DNA located near the anterior end, typically situated in front of the nucleus and close to the base of the flagellum
5. Single centrally located nucleus is present.

     Hence, the specimen seems to be Promastigote stage of Leishmania donovani

1. Small body, ovoid or round, about 2-5µm in diameter, lodged in vertebrate macrophage.
2. Periplast covered by the body.
3. Cytoplasm if differentiated into ectoplasm & endoplasm.
4. Endoplasm contains a central nucleus, a rod shaped kinetoplast & a basal body.

    Hence, the specimen seems to be Amastigote stage of Leishmania donovani
