E. coli (Escherichia coli)

E. coli (Escherichia coli) is a type of bacteria commonly found in the gut of warm-blooded animals and people.  E. coli naturally occurs in freshwater and is not usually harmful in itself. However, high concentrations of this bacteria exceeding water quality guidelines indicate faecal contamination which can be harmful to humans.
