Escherichia coli bacteria,coloured scanning electron micrograph. E. coli bacteria are a normal part of the intestinal flora in humans and other animals,where they aid digestion. However,some strains,for instance enterohaemorrhagic E. coli (EHEC),can produce a toxin (Shiga toxin) that leads to severe illness or even death. Normal strains can also produce infections in weakened or immunosuppressed people. Magnification: x7000 | |
