Bacterial contamination, SEM
Bacterial contamination, coloured scanning electron micrograph (SEM). Escherichia coli bacteria in a cell culture. This contamination has come from an unclean water source. These bacteria are a normal part of the intestinal flora in humans and other animals, where they aid digestion. However, some strains, for instance E. coli O157, can produce a toxin that leads to severe illness, or even death. Normal strains can also produce infections in weakened or immunosuppressed people.

EDITORS COMMENTS
This print captures the alarming reality of bacterial contamination. In this coloured scanning electron micrograph (SEM), Escherichia coli bacteria can be seen thriving in a cell culture, originating from an unclean water source. While E. coli is typically a beneficial part of our intestinal flora, aiding digestion in humans and animals, certain strains like E. coli O157 can produce a toxin that leads to severe illness or even death. The image showcases the intricate details of these microorganisms at a magnification of x6500 when printed at 10 centimetres across. The foul and dirty nature of this contamination is vividly portrayed through false colours used to enhance visibility under SEM. Bacteriology enthusiasts and microbiologists alike will appreciate the biological significance depicted here - highlighting how water supplies can become breeding grounds for harmful bacteria such as Escherichia coli. This serves as an important reminder about the potential dangers lurking within our environment. While not explicitly mentioned by Science Photo Library, it's worth noting that this photo should not be used for commercial purposes due to copyright restrictions. Nonetheless, its educational value cannot be understated as it sheds light on the critical issue of bacterial contamination and emphasizes the need for clean water sources to safeguard public health worldwide.
