E coli (escherichia coli)

One of the most common bacteria found in the world, investigation into the impact of this bacteria has shown some forms to be beneficial to humans especially as part of the gut bacteria population. Also commonly associated with food poisoning.

 

Escherichia coli is a rod-shaped bacterium that is the most widely studied prokaryotic model organism in biomedical research. Most strains are harmless, however some serotypes are pathogenic with different forms presenting different symptoms. It is frequently used in biotechnology to synthesise proteins introduced via recombinant DNA and a technique known as splicing.
