Shigella bacterium. Coloured scanning electron micrograph (SEM) of a Shigella sp. bacterium (orange) being engulfed by a macrophage white blood cell. This process is called phagocytosis. Macrophages are cells of the body's immune system. They phagocytose and destroy pathogens,dead cells and cellular debris. Shigella sp. are Gram-negative rod-shaped bacteria. They infect the large intestine,causing dysentery,which can vary in severity from a mild attack of diarrhoea to an acute infection. Magnification: x 11,650 when printed at 10 centimetres wide | |
