Introduction

The naming of bacteria is controlled by the International Code of Nomenclature of Prokaryotes (Parker et al., 2019). The correct name of a bacterial taxon is based on:

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

In 1980, the APPROVED LISTS OF BACTERIAL NAMES (Skerman et al., 1980) set a new starting point for bacterial names. Names that were not included in the APPROVED LISTS lost standing in bacterial nomenclature.

Valid publication of new names and new nomenclatural combinations can only be made by publication in the INTERNATIONAL JOURNAL OF SYSTEMATIC BACTERIOLOGY (IJSB)/ INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROCBIOLOGY (IJSEM) (from January 2000), either as an original article or in the "VALIDATION LISTS" regularly appearing in that journal. The VALIDATION LISTS constitute valid publication of new names and new combinations that were previously effectively published outside the IJSB/IJSEM.

Names not considered to be validly published should no longer be used or should be used in quotation marks (e.g."Bacillus mesentericus") to denote that the name is not validly published.

The APPROVED LISTS contain more than 2,200 names at the genus level and below and 124 names of higher taxa. Numerous Validation Lists have been published since then. To date, the total number of validly published bacterial species and genus names is considerably larger, even if one accounts for the presence of synonyms.

BACTERIAL NOMENCLATURE UP-TO-DATE includes all bacterial names which have been validly published since January 1 1980 and nomenclatural changes which have been validly published since then. It will be updated with the publication of each new issue of the IJSEM.

BACTERIAL NOMENCLATURE UP-TO-DATE has been compiled by the Leibniz Institute DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH. It is available electronically. DSMZ accepts no responsibility for any errors.

The risk group classification is based on the official regulations of the Federal Republic of Germany.
