Nomenclature of prokaryotes

A name is given to a taxonomic unit (taxon) and the relevant level for identification is the species level.
This site is not the right place to learn all about nomenclature, see DSMZ site [1] : "The naming of bacteria is controlled by the International Code of Nomenclature of Bacteria (Lapage et al., 1992). The correct name of a bacterial taxon is based on:

1. Valid publication
2. Legitimacy
3. Priority of publication "

"The Bacteriological Code (1990 Revision) applies to all procaryotes. The procaryotes include groups known by such names as Bacteria, Eubacteria, Archaea, Archaebacteria, Archaeobacteria, Cyanobacteria, Cyanophyceae, Schizomycetes, Schizophycetes" [2]
Species are defined today [3] on a phylogenetic base (member of the species are sharing a common ancester and a high degree of genome identity) and other type of data [4].

Nomenclature Databases

Of course, it remains possible to refer in the International Journal of Systematic and Evolutionary Microbiology [5] to collect the valid name (and Type Strain) of new species (either in a paper dealing with the species description or in Approved Lists of Bacterial Names). Older but validated names may be found in the Approved Lists of Bacterial Names (before 1980).
Fortunately DSMZ releases tables of the current situation (Bacterial Nomenclature Up-to-Date) [6]. This table is used by Bibi Le to decide whether the species name found in Bank Format fields

DEFINITION

ORGANISM

in Gen Bank is nomenclature compliant or not.
Another Nomenclature Data Base is the work of Pr J-P Euzeby, in Toulouse (France) [7]. This Nomenclature Data Base is very usefull for a manual work, but not structurated enougth (and not built) toward an automated seach.

Type Strains

In these two data bases the Type Strain of each species is given and Bibi Le uses it to built its TypeStrainDataBase?.
