The following tables list the species, and some higher groups, of pathogenic Eubacteria mentioned in the text. The classification of Bacteria, one of the three domains of life, is in constant flux as relationships become clearer through sampling of genetic sequences. Many groups at all taxonomic levels still have an undetermined relationship with other members of the phylogenetic tree of Bacteria. Bergey’s Manual of Systematics of Archaea and Bacteria maintains a published list and descriptions of prokaryotic species. The tables here follow the taxonomic organization in the Bergey’s Manual Taxonomic Outline. Bergey’s Manual Trust. Bergey’s Manual of Systematics of Archaea and Bacteria, Taxonomic Outline . 2012. http://www.bergeys.org/outlines.html
We have divided the species into tables corresponding to different bacterial phyla. The taxonomic rank of kingdom is not used in prokaryote taxonomy, so the phyla are the subgrouping below domain. Note that many bacterial phyla not represented by these tables. The species and genera are listed only under the class within each phylum. The names given to bacteria are regulated by the International Code of Nomenclature of Bacteria as maintained by the International Committee on Systematics or Prokaryotes.
