Astrovirus particles, TEM
Astrovirus particles. Coloured transmission electron micrograph (TEM) of a cluster of astrovirus particles (purple). These are small viruses, measuring approximately 28 nanometres in diameter. They contain a single strand of ribonucleic acid (RNA) genetic material within a icosahedral (20-sided) outer coat (capsid). Astroviruses are a major cause of gastroenteritis but have been poorly studied because they do not grow in a culture. Symptoms include nausea, headaches and diarrhoea. Magnification: x126, 000 when printed 10 centimetres tall

EDITORS COMMENTS
This print showcases a cluster of astrovirus particles, revealing their intricate structure and vibrant purple color. These tiny viruses, measuring only 28 nanometres in diameter, are responsible for causing gastroenteritis, a common intestinal disease. Despite their significance as a major cause of illness, astroviruses have remained poorly studied due to the challenge of growing them in culture. The image provides a close-up view of these pathogenic microorganisms under a transmission electron microscope (TEM). Each particle consists of an outer coat called capsid, which has an icosahedral shape with twenty sides. Within this protective shell lies a single strand of ribonucleic acid (RNA), the genetic material that enables viral replication. With its false-colored presentation and high magnification level (x126,000 when printed at 10 centimeters tall), this print not only captures the beauty and complexity of these astrovirus particles but also serves as an invaluable resource for researchers in virology and microbiology. By shedding light on the structure and characteristics of these elusive viruses, scientists can gain insights into their behavior and develop effective strategies to combat associated symptoms such as nausea, headaches, and diarrhea. This remarkable photograph from Science Photo Library is more than just art; it represents the intersection between biology and medicine—a visual testament to our ongoing quest to understand and conquer infectious diseases that affect millions worldwide.
