Coloured SEM of streptococcus pneumoniae

False colour scanning electron micrograph (SEM) of Streptococcus pneumoniae (pneumonococcus), a spherical, Gram-positive bacterium associated with pneumonia in humans. The bacteria secrete a viscous material to form a capsule around their cell wall. The role of the capsule is uncertain, but is associated with virulence in pathogenic organisms, conveying protection against the immune system of the host. Capsulated organisms resist phagocytosis (engulfing) by white blood cells and may survive digestion by scavengers cells, continuing to multiply normally. Magnification: x8000 at 6x7 cm size, x4000 at 35mm size

EDITORS COMMENTS
This print showcases a false-colour scanning electron micrograph (SEM) of Streptococcus pneumoniae, also known as pneumonococcus. This spherical, Gram-positive bacterium is notorious for causing pneumonia in humans. The image reveals the intricate details of this pathogenic organism, highlighting its unique features and potential dangers. One striking characteristic of S. pneumoniae is its ability to secrete a viscous material that forms a protective capsule around its cell wall. Although the exact role of this capsule remains uncertain, it has been associated with increased virulence in pathogenic organisms by providing protection against the host's immune system. The significance of this capsule becomes evident when considering how it aids the bacterium's survival strategies. Capsulated organisms like S. pneumoniae can resist phagocytosis, which refers to engulfing by white blood cells designed to eliminate foreign invaders. Additionally, they may even withstand digestion by scavenger cells while continuing their normal multiplication process. At an impressive magnification level of x8000 at 6x7 cm size or x4000 at 35mm size, this SEM image offers valuable insights into the world of microorganisms and bacteriology. It serves as a reminder that despite their minuscule size, these microbes possess remarkable adaptations that allow them to thrive and pose significant health risks to humans.
