Neutrophil cell and bacteria, SEM
Neutrophil cell and bacteria. Coloured scanning electron micrograph (SEM) of bacteria (rod-shaped) and part of a neutrophil cell (lower left). The neutrophil cell (a type of white blood cell) is extruding material towards the bacteria. It may be forming a net-like structure to trap them. This is called a NET (neutrophil extracellular trap). This previously unknown method of cellular defence was discovered in 2004. These are Shigella sp. bacteria, one of the causes of dysentery, a severe intestinal inflammation

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate battle between a neutrophil cell and bacteria. In this coloured scanning electron micrograph (SEM), we witness the remarkable defense mechanism of the human body at work. The rod-shaped bacteria, identified as Shigella sp. , are met with fierce resistance from a neutrophil cell, which is part of our immune system. The lower left corner reveals an extraordinary sight: the neutrophil cell extruding material towards the bacteria. This process is known as a NET (neutrophil extracellular trap), where the cell forms a net-like structure to ensnare and immobilize its adversaries. Discovered in 2004, this previously unknown method of cellular defense has revolutionized our understanding of how our bodies combat harmful pathogens. Shigella sp. , one of the culprits behind dysentery, triggers severe intestinal inflammation. Hence, witnessing this intense interaction between neutrophils and these pathogenic invaders sheds light on both disease pathology and immune responses within our digestive system. With its false-colored presentation through SEM, this print not only offers scientific insights but also serves as a testament to the beauty found within microbiology. It reminds us that even on a microscopic scale, there exists an awe-inspiring world full of battles fought by cells to protect our well-being.
