Enterobacterales with its type genus Enterobacter is an order of Gram-negative bacteria.
Historical identification and systematics
Enterobacterales was proposed in 2005 under the name "Enterobacteriales". However, the name "Enterobacteriales" was not validated, thus it lacked standing in nomenclature, so the name should be written in parentheses. "Enterobacteriales" was a monotypic order, containing only the family Enterobacteriaceae, and shared its type genus Escherichia.
In 2016, "Enterobacteriales" was proposed to be reclassified as Enterobacterales, and the type genus changed to Enterobacter. This was to avoid the confusion that would be generated by renaming the order to "Escherichiales"; in contrast, the name "Enterobacteriales" remains a commonly used synonym for the order. In addition, several new families within the Enterobacterales were proposed, consisting of species that were formerly members of the Enterobacteriaceae.

Validly published genera
The following genera have been validly published, thus they have "Standing in Nomenclature". The year the genus was proposed is listed in parentheses after the genus name.
