Escherichia coli (Migula 1895) Castellani and Chalmers 1919, species. (Type species of the genus.)
Type strain: (see also StrainInfo.net) ATCC 11775= CCUG 24 = CCUG 29300 = CIP 54.8 = DSM 30083 = JCM 1649 = LMG 2092 = NBRC 102203 = NCCB 54008 = NCTC 9001.

Note: Escherichia coli and the four species of the genus ¤ Shigella are a single species on the basis of DNA relatedness. Moreover, these taxa are often difficult to separate biochemically, and pathogenicity does not provide definitive separation (some Escherichia coli strains can cause a dysentery-like diarrhea). However, they remain separate species to avoid confusion in medical microbiology.
