With version 3.0.0, we’re releasing the most substantial update in the history of Mabritec Central. Over the past year we didn’t simply add data — we rebuilt the entire database from the ground up, with a sustained focus on coverage, consistency, and taxonomic quality.
3.0.0 in numbers
Version 3.0.0 more than doubles the scale of the database. It now holds:
- more than 580,000 genome assemblies
- more than 1.4 million ribosomal proteins
- 28,937 type strains
- 22,904 species
- 1,292 genomospecies
But scale is only the surface. Every entry was re-examined, re-classified, and re-curated to raise the overall quality of the data.
A complete rebuild for coverage and quality
Rather than extending the previous version incrementally, we started over. The entire dataset was reprocessed through a single, up-to-date pipeline. This removes historical inconsistencies, harmonises naming across the whole database, and ensures every genome is evaluated by the same modern criteria — giving you broader coverage and greater confidence in every result.
Taxonomy, curated in-house
At the heart of 3.0.0 is a thoroughly curated taxonomy. Every classification rests on two complementary lines of evidence: in-house Average Nucleotide Identity (ANI) calculations, and concatenated ribosomal protein analysis. Using both means each assignment is supported at the whole-genome level and by an independent, sequence-based signal.
This curation follows the official taxonomy of validly published species, so the names you see reflect the current, accepted nomenclature.
Just as importantly, we preserve biologically and clinically meaningful distinctions. Where closely related species show an ANI conflict at the 95% identity threshold, we keep them as distinct species rather than collapsing them into a single group. This applies to several well-known groups, for example:
- the Burkholderia cepacia complex
- Bordetella pertussis, B. parapertussis, and B. bronchiseptica
- the Bacillus cereus group
The practical benefit is sharper resolution exactly where it matters: species with real diagnostic relevance stay separable in your analyses.
A new genomospecies concept
For genomes that do not yet correspond to a validly published species, we’ve introduced a redesigned genomospecies concept — now comprising 1,292 genomospecies. Instead of arbitrary running numbers, each genomospecies is anchored to a representative assembly and expressed in the new MabrTax GCF_… format (for example, MabrTax GCF_000248195).
The advantage is stability: every genomospecies now has an unambiguous, fully traceable identifier tied to a real reference genome — one you can look up, cite, and rely on across releases.
Continuous monthly updates
Version 3.0.0 also changes how we deliver data. From now on, Mabritec Central follows a monthly update cycle, staying continuously in sync with newly published genomes and taxonomic changes. You’ll always be working with current data — no more waiting for the next major release.
Explore 3.0.0
Version 3.0.0 is live now. This milestone is the result of more than a year of dedicated work, and we’re glad to put it in your hands — a cleaner, more rigorously curated, and continuously maintained foundation for confident, species-level identification.
