E. coli bacteria. Coloured transmission electron micrograph (TEM) of a colony of Escherichia coli bacteria. This is a rod-shaped, Gram-negative species of bacteria. Some of the cells are dividing into pairs of \daughters\". E. coli is a normal inhabitant of the human intestine and is usually harmless. Under certain conditions its numbers may increase and cause infection. Some strains are responsible for gastroenteritis in children, particularly in tropical countries. In adults it is the cause of \"traveller's diarrhoea\" and of 80% of all urinary tract infections. It is also the organism most used in genetic studies. Magnification: x2,800 at 5x7cm size.
