E. coli bacteria. Transmission electron micrograph of an Escherichia coli bacterium. This rod-shaped, Gram-negative species of bacteria has numerous tail-like flagella (green) which help it move. 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. It can cause "traveller's diarrhoea" and 80% of all urinary tract infections. It is also the organism most used in genetic studies.Magnification:x4715 at 6x4.5mm.
