Escherichia coli bacteria,coloured transmission electron micrograph (TEM). 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)i,can produce a toxin that leads to severe illness or even death. Normal strains can also produce infections in weakened or immunosuppressed people. Magnification: x17.000 | |
