There is no widely accepted concept of species for prokaryotes, and assignment of isolates
to species is based on measures of phenotypic or genome similarity. The current methods …

Advancing prokaryotic taxonomy constitutes a contemporary academic challenge as well as
practical necessity. Genome sequencing has greatly facilitated the evaluation of the current …

The issues of microbial taxonomy and potential interactions with a microbial commons are
discussed, with emphasis on three components: characterization, classification and …

Taxonomic classification is an important field of microbiology, as it enables scientists to
identify prokaryotes worldwide. Although the current classification system is still based on …

The classification of life forms into a hierarchical system (taxonomy) and the application of
names to this hierarchy (nomenclature) is at a turning point in microbiology. The …

The species concept is a recurrent controversial issue that preoccupies philosophers as well
as biologists of all disciplines. Prokaryotic species concept has its own history and results …

To help advance the species definition for prokaryotes, we have compared the gene content
of 70 closely related and fully sequenced bacterial genomes to identify whether species …

The exponentially increasing number of sequenced genomes necessitates fast, accurate,
universally applicable and automated approaches for the delineation of prokaryotic species …

Direct molecular analyses of natural microbial populations reveal patterns that should
compel microbiologists to adopt a more natural species concept that has been known to …

▪ Abstract Bacterial systematics has not yet reached a consensus for defining the
fundamental unit of biological diversity, the species. The past half-century of bacterial …
