Shigella bacterium and macrophage, SEM C016 / 8922
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 bodys 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

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate relationship between a Shigella bacterium and a macrophage, providing a glimpse into the fascinating world of immunology. In this coloured scanning electron micrograph (SEM), we witness the process of phagocytosis, as an orange-hued Shigella sp. bacterium is engulfed by a white blood cell known as a macrophage. Macrophages play a crucial role in our body's defense system, tirelessly patrolling for pathogens, dead cells, and cellular debris to phagocytose and destroy. This image beautifully captures their defensive prowess in action. Shigella sp. , Gram-negative rod-shaped bacteria responsible for causing dysentery, are depicted here at an astonishing magnification of x 11,650 when printed at 10 centimeters wide. The severity of dysentery can range from mild diarrhea to acute infection. The use of scanning electron microscopy allows us to delve into the microscopic realm where these biological interactions occur. It provides invaluable insights into microbiological processes that shape our understanding of infections and immune responses. This mesmerizing image serves as both an artistic representation and scientific documentation—an ode to the intricacies of life on a minuscule scale. It reminds us of the constant battle within our bodies between harmful invaders and our remarkable immune system's relentless defense mechanisms.
