Due to the close systematic relationships within the tribe Escherichieae, definition of the taxon Shigella should be based primarily on the potential enteropathogenicity of the dysentery types. Immobile and anaerogenic dysentery bacilli possessing biochemical activities exceeding the established Shigella norm could be included in Shigella subgroup D, to which should be given the name S. metadysenteriae to avoid misunderstandings resulting from lipopolysaccharide phase designations I and II of S. sonnei. S. sonnei, serotypes 792 and serotype 147, and S. guanabara are proposed to be listed as serotypes 1 to 4 of S. metadysenteriae. Regularly aerogenic and/or motile dysentery types of the tribe Escherichieae—E. coli O124, O136, O143, O144, and O152—could be placed for the present into a provisional taxon Escherichia dysenteriae.
