False-colour transmission electron micrograph of a rod-shaped bacterium, Shigella sp., a pathogenic strain causing dysentery. Dysentery, affecting mainly the large intestines, varies in severity from a mild attack of diarrhoea to an accute infection. Until the introduction of the drug sulphonamides in the late 1930s it was a killer disease all over the world. It still is among the young, elderly & malnourished. The infection is spread by flies, direct contact, & water contaminated by faeces containing the bacillus. Magnification: x15,600 at 6x4.5cm size.
