F / col TEM of Corynebacterium diphtheria
False-colour transmission electron micrograph (TEM) of Corynebacterium diphtheria, showing a number of the Gram-positive, non-sporing, aerobic bacilli (rod-shaped bacteria) which are the causative agents of diphtheria. C. diphtheria is an obligate human parasite - man is its only natural host - causing an infection of the upper respiratory tract. Other effects arise from the production of an exotoxin which enters the bloodstream and damages the heart, nervous system, liver, kidneys and adrenal glands. The bacilli are slightly curved, and their appearance has earned them the name of " chinese characters". Mag: x13, 000 at 35mm size, x26, 000 at 6x7cm size

EDITORS COMMENTS
This print showcases a false-colour transmission electron micrograph (TEM) of Corynebacterium diphtheria, the causative agent of diphtheria. The image reveals numerous Gram-positive, non-sporing, aerobic bacilli or rod-shaped bacteria that are responsible for this infectious disease. C. diphtheria is an obligate human parasite, exclusively infecting humans and primarily affecting the upper respiratory tract. However, the detrimental effects of this bacterium extend beyond its colonization in the respiratory system. It produces an exotoxin that enters the bloodstream and wreaks havoc on various organs including the heart, nervous system, liver, kidneys, and adrenal glands. The slightly curved appearance of these bacilli has earned them the nickname "chinese characters" adding a visual intrigue to their microscopic world. This particular TEM image was captured at magnifications of x13,000 for a 35mm size print and x26,000 for a 6x7cm size print. Bacteriology enthusiasts will appreciate this stunning portrayal as it delves into the intricate details of bacterial morphology and highlights how seemingly innocuous organisms can cause significant harm to our bodies. With its emphasis on transmission electron microscopy (TEM), this photograph offers valuable insights into microbial biology while shedding light on one of humanity's oldest foes - infectious diseases caused by bacteria like Corynebacterium diphtheria.
