Leishmania spp. is a type of parasite that causes the disease Leishmaniasis. During its life cycle, it alternates between two distinct forms:

1. Promastigote Form: This is the form that exists within the sandfly vector. In this form, the parasite has a long, whip-like tail (flagellum) that it uses for movement. It is in this form that the parasite is injected into a mammalian host when the sandfly takes a blood meal.

2. Amastigote Form: Once inside the mammalian host, the parasite transforms into the amastigote form. This form is smaller, round, and does not have a flagellum. It is adapted to survive and replicate within the harsh conditions of the phagolysosome, an acidic compartment inside the host's immune cells.

The parasite continues to alternate between these two forms as it is transmitted between sandfly and mammalian hosts, completing its life cycle.
