The difference between them:
① Coliform bacteria refers to a group of Gram-negative Bacillus which can ferment lactose, produce acid and gas, and are aerobic and facultative anaerobic.
Coliform bacteria are not classified and named in bacteriology, but bacteria related to fecal pollution, which are put forward according to the requirements of hygiene, that is, as indicators of whether food and water have been polluted by human and animal feces. These bacteria are not completely consistent in biochemistry and serology. According to further biochemical tests, these bacteria can be further divided into Escherichia coli (commonly known as Escherichia coli), Citrobacter freundii, Klebsiella pneumoniae and Enterobacter cloacae.
② Escherichia coli (also known as Escherichia coli), classified in Enterobacteriaceae, belongs to the genus Escherichia.
Escherichia coli refers to Gram-negative Bacillus, bacteria which produce acid and gas by lactose fermentation, and whose imvic test (indigo substrate, mr, v-p, citrate test) is +

Escherichia coli related to human beings are collectively called diarrheal Escherichia coli, including five kinds: enterotoxigenic Escherichia coli (etec), pathogenic Escherichia coli (epec), hemorrhagic Escherichia coli (ehec), invasive Escherichia coli (eiec) and adherent Escherichia coli (eaec).
