Background and history

From the first identification of a bacterial species in 1872, microbial species were named according to the binomial nomenclature, based on largely subjective descriptive characteristics. [2] By the end of the 19th century, however, it was clear that this nomenclature and classification system required reform. Although several different comprehensive nomenclature systems were invented (most notably, that described in Bergey's Manual of Determinative Bacteriology , first published in 1923), none gained international recognition. In 1930, a single international body, now named the International Committee on Systematics of Prokaryotes (ICSP), was established to oversee all aspects of prokaryotic nomenclature. Work began in 1936 on drafting a Code of Bacteriological Nomenclature, the first version of which was approved in 1947. [2]

In 1950, at the 5th International Congress for Microbiology, a journal was established to disseminate the committee's conclusions to the microbiological community. It first appeared the following year under the title of International Bulletin of Bacteriological Nomenclature and Taxonomy. [2] In 1980, the ICSP published an exhaustive list of all existing bacterial species considered valid in the Approved Lists of Bacterial Names. [2] Thereafter, the committee's Code required all new names to be either published or indexed in its journal to be deemed valid. [5]

The journal was at first published quarterly by Iowa State College Press, [2] which later increased to bimonthly. In 1966, the journal was renamed the International Journal of Systematic Bacteriology. [2] [6] For decades, the journal's cover quoted Dutch naturalist Otto Friedrich Müller: "the sure and definite determination (of species of bacteria) requires so much time, so much acumen of eye and judgement, so much of perseverance and patience that there is hardly anything else so difficult." [7] Between 1971 and the end of 1997, the journal was published by the American Society for Microbiology. [2] [6] [8]

Publication moved to the United Kingdom in 1998, the journal being taken over by the Society for General Microbiology, in conjunction with Cambridge University Press. [6] The title was changed to International Journal of Systematic and Evolutionary Microbiology in 2000, to reflect the broadened focus of the journal. A major redesign brought the journal into line with the three other society journals in 2003, and at the same date the printer/typesetter changed to the Charlesworth Group. The frequency increased to monthly in 2006. [6]

Role in nomenclature validation

The journal publishes research papers establishing novel prokaryotic names, which are summarized in a notification list. Each monthly issue also contains a compilation of validated new names (the validation list) that have been previously published in other scientific journals or books. [2] [3] [5] Since August 2002, publications relating to new bacterial taxa and validation of publication elsewhere have both required type strains to have been deposited at two recognised public collections in different countries. [5] [9]

As of 2007, the journal has officially validated around 6500 species and 1500 genera. [2] It was estimated in 2004 that over 300 new names had been published but not validated. [5]

Modern journal

As of 2017, the editor-in-chief is Martha E. Trujillo (University of Salamanca). [1]

According to the Journal Citation Reports , the journal has a 2022 impact factor of 2.8. [10]

Pseudomonadota is a major phylum of Gram-negative bacteria. The renaming of several prokaryote phyla in 2021, including Pseudomonadota, remains controversial among microbiologists, many of whom continue to use the earlier name Proteobacteria, of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as Escherichia, Salmonella, Vibrio, Yersinia, Legionella, and many others. Others are free-living (non-parasitic) and include many of the bacteria responsible for nitrogen fixation.

<span class="mw-page-title-main">Korarchaeota</span> Proposed phylum within the Archaea

The Korarchaeota is a proposed phylum within the Archaea. The name is derived from the Greek noun koros or kore, meaning young man or young woman, and the Greek adjective archaios which means ancient. They are also known as Xenarchaeota. The name is equivalent to Candidatus Korarchaeota, and they go by the name Xenarchaeota or Xenarchaea as well.

The Thermomicrobia is a group of thermophilic green non-sulfur bacteria. Based on species Thermomicrobium roseum and Sphaerobacter thermophilus, this bacteria class has the following description:

<span class="mw-page-title-main">Chlamydiota</span> Phylum of bacteria

The Chlamydiota are a bacterial phylum and class whose members are remarkably diverse, including pathogens of humans and animals, symbionts of ubiquitous protozoa, and marine sediment forms not yet well understood. All of the Chlamydiota that humans have known about for many decades are obligate intracellular bacteria; in 2020 many additional Chlamydiota were discovered in ocean-floor environments, and it is not yet known whether they all have hosts. Historically it was believed that all Chlamydiota had a peptidoglycan-free cell wall, but studies in the 2010s demonstrated a detectable presence of peptidoglycan, as well as other important proteins.

Mollicutes is a class of bacteria distinguished by the absence of a cell wall. The word "Mollicutes" is derived from the Latin mollis, and cutis. Individuals are very small, typically only 0.2–0.3 μm in size and have a very small genome size. They vary in form, although most have sterols that make the cell membrane somewhat more rigid. Many are able to move about through gliding, but members of the genus Spiroplasma are helical and move by twisting. The best-known genus in the Mollicutes is Mycoplasma. Colonies show the typical "fried-egg" appearance.

<span class="mw-page-title-main">Candidatus</span> Indication in bacteriological nomenclature

In prokaryote nomenclature, Candidatus is used to name prokaryotic taxa that are well characterized but yet-uncultured. Contemporary sequencing approaches, such as 16S ribosomal RNA sequencing or metagenomics, provide much information about the analyzed organisms and thus allow to identify and characterize individual species. However, the majority of prokaryotic species remain uncultivable and hence inaccessible for further characterization in in vitro study. The recent discoveries of a multitude of candidate taxa has led to candidate phyla radiation expanding the tree of life through the new insights in bacterial diversity.

The International Code of Nomenclature of Prokaryotes (ICNP) or Prokaryotic Code, formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC), governs the scientific names for Bacteria and Archaea. It denotes the rules for naming taxa of bacteria, according to their relative rank. As such it is one of the nomenclature codes of biology.

Parachlamydiaceae is a family of bacteria in the order Chlamydiales. Species in this family have a Chlamydia–like cycle of replication and their ribosomal RNA genes are 80–90% identical to ribosomal genes in the Chlamydiaceae. The Parachlamydiaceae naturally infect amoebae and can be grown in cultured Vero cells. The Parachlamydiaceae are not recognized by monoclonal antibodies that detect Chlamydiaceae lipopolysaccharide.

Alteromonas is a genus of Pseudomonadota found in sea water, either in the open ocean or in the coast. It is Gram-negative. Its cells are curved rods with a single polar flagellum.

In botanical nomenclature, a validly published name is a name that meets the requirements in the International Code of Nomenclature for algae, fungi, and plants for valid publication. Valid publication of a name represents the minimum requirements for a botanical name to exist: terms that appear to be names but have not been validly published are referred to in the ICN as "designations".

The International Committee on Systematics of Prokaryotes (ICSP), formerly the International Committee on Systematic Bacteriology (ICSB), is the body that oversees the nomenclature of prokaryotes, determines the rules by which prokaryotes are named and whose Judicial Commission issues Opinions concerning taxonomic matters, revisions to the Bacteriological Code, etc.
