False-colour light micrograph (LM) of a colony of Leishmania tropica., a parasitic flagellate protozoan that causes the disease leishmaniasis in humans. The parasite assumes a different form in each of its two hosts, humans & the sandfly, its insect carrier. This colony is comprised of promastigote forms from the insect host, with protuding flagella (blue). In its human host the parasite (in its amastigote form) appears as small round features, with retracted, rudimentary flagella. Human infection affects the bone marrow, spleen & lymphatic system.
