Malaria. Coloured transmission electron micrograph (TEM) of a human red blood cell (red) infected with the malarial parasite Plasmodium sp. (blue). The single-celled Plasmodium parasites are seen in the swollen region of the cell. Malaria is spread to humans by species of tropical mosquitoes (Anopheles sp.). Infection spreads from the liver to the blood, where the plasmodium multiplies inside red blood cells. Release of mature Plasmodium results in further infection and produces bouts of shivering fever and sweating that may be fatal. Magnification: x13,000 at 5x7cm size. x45,000 at 6.5x9.5"~LANDSCAPE"
