Large type strain database

In microbial taxonomy a type strain is the nomenclatural type of a
species. Whether or not a novel strain belongs to a particular species is
thus determined by comparison to type strains. The comprehensive TYGS
database contains a comprehensive collection of
currently 11819
microbial type-strain genomes.

Fast, reliable and easily interpretable analyses

The TYGS web service implements many established methods
(GGDC, GBDP)
from recent years and provides fast data analysis on an entirely new
level.

Type-based
species and subspecies clusters

The classification or identification of novel strains is
done by a dedicated type-based species clustering as opposed to just some
arbitrary de-novo clustering at the species or subspecies delimitation
threshold. This clustering takes nomenclatural priority and taxonomic
conservatism into account. The reported clusters can be visualized on the
resulting trees to generate instructive figures.

Truly genome-based phylogenetic trees.
With branch support.

Many published "genome-based" phylogenetic trees are only
based on a fraction of the genes found in the involved genomes. In other
cases trees based on a larger, more representative set of genes are
presented but without statistical support for the branches; some methods
suggested for genome-based taxonomy are even unable to calculate branch
support in the first place. In yet other cases authors present clusterings
instead of phylogenetic trees. To the contrary, TYGS uses the Genome BLAST
Distance Phylogeny (GBDP) method which addresses all of these aspects.
