Leishmaniasis. Light micrograph of a section through a human liver,showing a white blood cell (centre) infected by Leishmania donovani,the par- asitic protozoan causing visceral leishmaniasis. The protozoa are the pale dots in the cell's cytoplasm (purple). L. donovani switches between two main forms during its life-cycle,one living in each of its hosts: humans and sandflies. These amastigotes (Leishman-Donovan bodies) occur in humans. The parasite passes between the hosts when sandflies feed on human blood. Without drug treatment,visceral leishmaniasis (kala-azar) can be fatal. Brightfield illumination. Magnification: x400 at 35mm size | |
