Macrophage engulfing protozoan. Coloured scanning electron micrograph (SEM) of a macrophage white blood cell (brown) engulfing (phagocytosing) a Leishmania sp. protozoan (green). The macrophage,part of the body's immune system,surrounds the protozoan,engulfs it and destroys it,a process known as phagocytosis. This parasitic protozoan causes the tropical disease leishmaniasis,which is transmitted by the bites of infected sandflies and can be fatal | |
