Influenzavirus B, TEM

Influenzavirus B. Coloured transmission electron micrograph (TEM) of particles of the influenza B virus, which is the cause of influenza (flu) in humans. The virus particles have an enveloped outer coat, or capsid, bearing the proteins (green) haemagglutinin (H) and neuraminidase (N), which allow the virus to enter and leave host cells. As with all viruses, influenza cannot reproduce by itself, instead entering cells and hijacking their biochemical machinery to produce more copies of the virus. Flu usually causes lethargy, aching muscles, fever and nausea. Influenza B, however, is less virulent than influenza A, due to the limited host range and its slower rate of evolution (by 2 to 3 times)

EDITORS COMMENTS
This print showcases the Influenzavirus B, a notorious virus responsible for causing influenza or flu in humans. The image, captured using a transmission electron microscope (TEM), reveals the intricate details of these viral particles. Adorned with an enveloped outer coat, known as the capsid, the virus flaunts its vibrant green proteins - haemagglutinin (H) and neuraminidase (N). These proteins play a crucial role in enabling the virus to invade and exit host cells. Unlike other viruses, such as Influenza A, Influenza B exhibits lower virulence due to its limited host range and slower rate of evolution. However, it still manages to wreak havoc on our bodies by infiltrating cells and exploiting their biochemical machinery to replicate itself. As a result, individuals infected with this strain often experience lethargy, muscle pain, fever, and nausea. This visually striking micrograph not only highlights the pathogenic nature of Influenzavirus B but also serves as a reminder of the complex world of microbiology. It underscores how viruses like these rely on hijacking our cellular processes for survival and propagation. Captured by Science Photo Library's talented photographers using advanced microscopy techniques, this print is both scientifically informative and artistically mesmerizing. It offers viewers an opportunity to delve into the microscopic realm where pathogens like Influenza B thrive while emphasizing the importance of understanding these microorganisms for medical research purposes.
