Macrophage engulfing TB bacteria, SEM C014 / 0590

Macrophage engulfing TB bacteria. Coloured scanning electron micrograph (SEM) of a macrophage white blood cell engulfing a tuberculosis (Mycobacterium tuberculosis) bacterium (blue). This process is called phagocytosis. Macrophages are cells of the bodys immune system. They phagocytose and destroy pathogens, dead cells and cellular debris. Magnification: x4755 when printed at 10 centimetres wide

EDITORS COMMENTS
This print from Science Photo Library showcases the incredible defensive abilities of our immune system. In this coloured scanning electron micrograph (SEM), we witness a macrophage, a white blood cell, engulfing a tuberculosis bacterium. The blue hue of the bacterium stands out against the backdrop, emphasizing its infectious nature. Phagocytosis, the process depicted here, is an essential mechanism employed by macrophages to protect our bodies from harmful pathogens. These remarkable cells not only identify and target invading bacteria but also eliminate dead cells and cellular debris. The magnification level of x4755 allows us to appreciate the intricate details captured in this image when printed at 10 centimetres wide. It serves as a reminder of the microscopic battles taking place within our bodies every day. Immersed in shades of protection and defense, this photograph encapsulates both biology and medicine. Its visual narrative highlights how these tiny warriors play a crucial role in combating infections like tuberculosis. As we marvel at this mesmerizing display under the scanning electron microscope, we gain insight into immunology and microbiology while acknowledging the relentless efforts made by our immune system to safeguard us against diseases.
