Taxonomy

Until the 2021 revision of bacterial taxonomy by the ICSP, the entire phylum was classified within the Proteobacteria (synonym Pseudomonadota) as the Epsilonproteobacteria and the Desulfurellales. The separation of this phylum from "Proteobacteria" was originally proposed in 2017, using GTDB-based methods.

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).
