E. coli bacterium strain O157: H7, TEM
E. coli bacterium strain O157:H7, coloured transmission electron micrograph (TEM). E. coli are Gram-negative rod-shaped bacteria that are part of the normal flora of the human gut. Although most are harmless, some strains produce a toxin that causes severe diarrhoea and can be fatal. E. coli O157:H7 is an enterohemorrhagic strain, which causes bloody diarrhoea, and occasionally kidney failure, especially in young children and elderly people

EDITORS COMMENTS
This print showcases the E. coli bacterium strain O157:H7, captured through a coloured transmission electron micrograph (TEM). The image reveals the intricate details of these Gram-negative rod-shaped bacteria, which are commonly found in the human gut as part of our normal flora. While most strains of E. coli are harmless, this particular strain produces a potent toxin that can lead to severe diarrhoea and even prove fatal. E. coli O157:H7 is classified as an enterohemorrhagic strain due to its ability to cause bloody diarrhoea, posing a significant threat especially to young children and elderly individuals who may experience kidney failure as well. This false-coloured depiction sheds light on the pathogenic nature of these bacteria, emphasizing their role in gastroenteritis and highlighting their unique features such as flagella for movement. The microscopic world unraveled by this photograph offers valuable insights into microbiology and bacteriology studies. It serves as a reminder that within our bodies exists an intricate ecosystem where both beneficial and harmful microorganisms coexist. Science Photo Library's dedication to capturing such remarkable images allows us to appreciate the complexity of life at its smallest scale while deepening our understanding of infectious diseases caused by pathogens like E. coli.
