Bacteria infecting macrophage cells, SEM

Bacteria infecting macrophage cells. Coloured scanning electron micrograph (SEM) of Bacillus anthracis bacteria (purple) infecting macrophage white blood cells. The macrophages, when activated, will engulf (phagocytose) the bacteria and destroy them as part of the bodys immune response. B. anthracis is a Gram-positive, spore-forming bacteria that causes anthrax. It can infect the skin (cutaneous anthrax), causing raised itchy lesions, the lungs (pulmonary anthrax), which is fatal unless treated quickly, and the digestive system (gastrointestinal anthrax), causing vomiting of blood and severe diarrhoea. All forms can be fatal if left untreated. Treatment is with antibiotics

EDITORS COMMENTS
This print showcases the intricate relationship between bacteria and macrophage cells. In this colored scanning electron micrograph (SEM), we witness Bacillus anthracis bacteria, depicted in a striking purple hue, infecting macrophage white blood cells. These remarkable macrophages play a crucial role in our body's immune response by engulfing and destroying harmful pathogens like B. anthracis. Bacillus anthracis is a Gram-positive, spore-forming bacterium notorious for causing the deadly disease known as anthrax. This versatile pathogen can invade different parts of the body, leading to various forms of the illness with severe consequences if left untreated. Cutaneous anthrax affects the skin and results in raised itchy lesions; pulmonary anthrax attacks the lungs and is often fatal unless promptly treated; gastrointestinal anthrax impacts the digestive system, causing vomiting of blood and severe diarrhea. The image not only highlights the biological aspects but also raises awareness about potential biohazards associated with such dangerous bacteria. Bioterrorism remains a significant concern due to organisms like B. anthracis being used as agents for biological warfare. Fortunately, medical science has developed effective treatments using antibiotics to combat these infections successfully. As we delve into this visually stunning photograph from Science Photo Library, let us appreciate both its scientific significance and its reminder of how vital ongoing research is to protect ourselves against infectious diseases that pose threats to public health worldwide
