Shigella bacterium and macrophage, SEM C016 / 8924
Shigella bacterium. Coloured scanning electron micrograph (SEM) of a Shigella sp. bacterium (green) 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 colored scanning electron micrograph (SEM), we witness the process of phagocytosis, as a green-colored Shigella sp. bacterium is engulfed by a white blood cell known as a macrophage. Macrophages are vital components of our body's immune system, responsible for identifying and eliminating pathogens, dead cells, and cellular debris. This image captures their defensive role in action as they phagocytose and destroy harmful invaders like Shigella bacteria. Shigella sp. , gram-negative rod-shaped bacteria seen here, specifically target the large intestine causing dysentery – an infection that ranges in severity from mild diarrhea to acute illness. The magnification level of x 11,650 allows us to appreciate the microscopic details when printed at just 10 centimeters wide. Immersing ourselves in this visually stunning SEM photograph reminds us of the complex interactions occurring within our bodies every day. It highlights both the beauty and importance of biology in defending against infections while shedding light on microbiological research.
