Campylobacter bacteria. Coloured transmission electron micrograph (TEM) of two Campylobacter rectus bacteria. These Gram-negative rod-shaped bacteria have single flagellum (hair-like strand) that is used for movement. This species is strongly associated with periodontal diseases, including gingivitis and periodontitis, in humans. Periodontal diseases are due to infections of the gum tissues around the teeth. They eventually lead to loosened and lost teeth due to a lack of support by the gums. C. rectus infections can be prevented by using antibacterial toothpastes and mouthwashes. Treatment is by professional cleaning and the insertion of wafers containing antibiotics beneath the gumline. Magnification x27,000 when printed 10 centimetres...
About the Artist - Hazel Appleton, Centre For Infectionshealth Protection Agency
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
