E. coli induced cell death. Coloured scanning electron micrograph (SEM) of a macrophage white blood cell (centre) that is being destroyed by toxins released by Escherichia coli (E. coli) bacteria (rod-shaped). These toxins disrupt the macrophage's cell membrane, resulting in death of the cell. Magnification x2000, when printed at 10 centimetres wide.
