Clostridium perfringens bacterium
False-colour transmission electron micrograph (TEM) of Clostridium perfringens (alternative name Clostridium welchii or Welchs bacillus), an individual Gram-positive, anaerobic, spore-forming bacterium that causes blood poisoning, types of food poisoning & gas gangrene in man. C. perfringens secretes exotoxins; one of which, alpha-toxin (a lecithinase enzyme) has the ability to destroy plasma membranes surrounding cells - a possible cause of tissue damage in gas gangrene. Food poisoning from C. perfringens results from eating foods where the species has developed & formed exotoxins. Magnification: x15, 000 at 35mm size, x30, 000 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate details of a Clostridium perfringens bacterium, captured through a false-colour transmission electron micrograph (TEM). Also known as Clostridium welchii or Welchs bacillus, this individual Gram-positive, anaerobic, spore-forming bacterium is notorious for causing various health issues in humans. It is responsible for blood poisoning, different types of food poisoning, and gas gangrene. C. perfringens possesses the ability to secrete exotoxins that can be detrimental to our well-being. One such toxin is alpha-toxin, an enzyme called lecithinase that has the power to destroy plasma membranes surrounding cells. This destructive action could potentially lead to tissue damage seen in cases of gas gangrene. Food poisoning caused by C. perfringens occurs when individuals consume contaminated foods where this species has thrived and produced exotoxins. The consequences can range from mild discomfort to severe illness. The magnification used in capturing this image is truly remarkable: x15,000 at 35mm size and x30,000 at 6x7cm size. Such high-resolution imaging allows scientists and researchers in the fields of transmission microscopy, bacteriology, microbiology, and infectious diseases to study these microbes closely. This stunning photograph serves as a reminder of the hidden world teeming with microscopic organisms that impact our lives in both positive and negative ways.
