Introduction
The two prokaryotic domains (or empires), "Bacteria" (or "Eubacteria") and "Archaea" (or "Archaeobacteria"), are subdivided into 40 phyla (or divisions): 35 phyla in the domain "Bacteria", and 5 phyla in the domain "Archaea".
This file provides, alphabetically, the list of phyla included in the domains "Bacteria" and "Archaea". The classes, subclasses, orders, suborders, families and genera included in the phyla are also cited.
Taxa above the rank of class are not covered by the Rules of the Bacteriological Code (1990 Revision). Such names cannot be validly published and they are cited below in quotes.
Total number of names cited in this file: 2 domains, 40 phyla, 94 classes, 1 subclasses, 199 orders, 20 suborders, 469 families and 2998 genera.
A note on unassigned taxa
Unassigned taxa (families, orders, classes and phyla) have not been properly classified but are given here as placeholders for their child taxon in the hierarchical classification.
