Macrophage engulfing TB bacteria, SEM C014 / 0593

Macrophage engulfing TB bacteria. Coloured scanning electron micrograph (SEM) of a macrophage white blood cell engulfing a tuberculosis (Mycobacterium tuberculosis) bacterium (purple). This process is called phagocytosis. Macrophages are cells of the bodys immune system. They phagocytose and destroy pathogens, dead cells and cellular debris. Magnification: x12, 500 when printed at 10 centimetres wide

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate process of a macrophage engulfing tuberculosis (TB) bacteria. In this colored scanning electron micrograph (SEM), we witness the defensive power of a macrophage, a white blood cell responsible for protecting our bodies against harmful pathogens. The purple-hued TB bacterium is being devoured by the macrophage through phagocytosis, an essential mechanism in our immune system's arsenal. Macrophages act as vigilant soldiers, patrolling our body to identify and destroy invading organisms such as bacteria, dead cells, and cellular debris. At a magnification of x12,500 when printed at 10 centimeters wide, this image reveals the microscopic battlefield within us. The vibrant colors highlight the biological significance of this interaction between host and pathogen. Immersed in biology and medicine, this photograph symbolizes both protection and disease. It serves as a reminder of how our immune system acts as an unwavering defense force against infections like TB. Through their relentless attacks on pathogens like Mycobacterium tuberculosis, macrophages play a crucial role in safeguarding our health. With its scientific depth and aesthetic appeal, this SEM print offers insights into immunology while showcasing the wonders hidden within us at a microscopic level.
