Computer artwork of the inner structure of an Escherichia coli bacterium. Shown are the pili and capsule (yellow),the membrane (green),the ribosome (light blue) and the DNA (blue). 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 | |
