Light micrograph of the malaria parasite, Plasmo- dium sp., parasitising a red blood cell. At upper left, an infected red blood cell contains the internal dumb-bell shaped stage of this parasite. Other parasites (centre, blue) are seen among the blood cells. Malaria is spread by the mosquito Anopheles sp., which deposits the Plasmodium para- site whilst sucking a human's blood. The parasite enters the liver, reproduces, then enters red blood cells to grow and multiply further. Infected red blood cells are destroyed and the patient becomes anaemic, suffering from recurrent fevers. Magnification: x320 at 6x4.5cm, x192 at 35mm size.
