Short description
This article lists the orders of the Bacteria . The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[ 1] National Center for Biotechnology Information (NCBI)[ 2] phylogeny is based on 16S rRNA-based LTP release 132 by The All-Species Living Tree Project.[ 3]
Phylogeny
National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using phylorank and the taxonomy manually curated to remove polyphyletic groups.[ 4] [ 5] [ 6] [ 7] [ 8]
Cladogram was taken from GTDB release 10-RS226 (16th April 2025).[ 9] [ 10] [ 11]
