Description
Macrophage engulfing Leishmania. Coloured scanning electron micrograph (SEM) of a macrophage engulfing a Leishmania sp. parasite (blue). Leishmania is a parasitic protozoan that causes the tropical disease leishmaniasis. Here, the macrophage, a type of white blood cell, has extended part of its body (yellow) to capture the Leishmania. This process is called phagocytosis. Leishmaniasis is transmitted to humans by bites of infected sandflies, causing a skin ulcer at the site of the bite. Macrophages are part of the immune system and keep the body free of invading organisms. Magnification: x1,950 at 6x7cm size.
