Leishmania protozoa. Coloured transmission electron micrograph (TEM) of a white blood cell (centre) infected by Leishmania sp. (purple). These parasitic protozoa cause kala-azar (visceral leishmaniasis),when they invade internal organ body cells. Leishmania switch between two forms during their life-cycles,one living in each of their hosts: humans and sandflies. In human cells they are known as Leishman-Donovan bodies. They pass between their hosts when sandflies feed on human blood. Kala-azar causes open sores and ulcers on the skin and internal organs,without treatment it may be fatal. Magnification unknown | |
