Enterobacterales with its type genus Enterobacter is an order of Gram-negative bacteria.[1]

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.[2][3][4]

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.[1] The Thorselliaceae may also be considered a member of this order.[5]
