  • The four species of Shigella and Escherichia coli 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. Publication: Brenner DJ. Family I. Enterobacteriaceae Rahn 1937, Nom. fam. cons. Opin. 15, Jud.
