E. coli bacterium. Coloured scanning electron micrograph (SEM) of Escherichia coli bacterium. E.coli are Gram-negative rod-shaped bacteria that are part of the normal flora of the human gut. Some strains produce a toxin that causes severe diarrhoea and can be fatal,especially in the very young or elderly. The hair-like tendrils are the flagella,which the bacterium uses as propellers to move around. Magnification: x 25,000 when printed at 10 centimetres high | |
