Computer artwork of the inner structure of a 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 | |
