Abstract

fetched live from OpenAlex

The diverse members of the Enterobacterales are agriculturally and medically relevant species that have continued to undergo taxonomic revision. To assess the current taxonomy of 64 genera of the Enterobacterales , we carried out a phylogenetic analysis using 32 single-copy core proteins. The resulting phylogeny was robust, and shows that eight genera – Biostraticola , Enterobacillus , Gibbsiella , Limnobaculum , Izhakiella , ‘Nissabacter’, Rosenbergiella and Samsonia – are currently assigned to incorrect families. Taxonomic reassignment of these genera was also supported by average amino acid identity comparisons. We propose taxonomic revision of these genera to reflect their phylogenetic position within the Enterobacterales .

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
