Abstract
Abstract Eg.ger.thel.la.ce'ae. N.L. fem. n. Eggerthella type genus of the family; suff. ‐ aceae ending to denote a family; Eggerthellaceae the Eggerthella family. The family contains the type genus Eggerthella and the following validly published genera: Adlercreutzia, Cryptobacterium, Denitrobacterium, Ellagibacter, Enteroscipio, Gordonibacter , Paraeggerthella, Parvibacter, Rubneribacter , Senegalimassilia , and Slackia . Of these genera, the genus Parvibacter, containing the species Parvibacter caecicola , was recently merged with the genus Adlercreutzia . However, evidence presented indicates that P. caecicola , which remains a validly published name, is distinct from other Adlercreutzia species and hence is retained within the genus Parvibacter . Besides the genera with validly published names, the following effectively published genera “ Arabia ,” “ Hugonella ,” “ Phoenicibacter ,” and “ Raoultibacter ” are also part of this family. The members are Gram‐positive rods or cocci and asaccharolytic except some species. Most members contain enzymes responsible for hydrolyzing amino acids such as arginine and leucine, and their growth is stimulated in the presence of arginine and some other amino acids. Most members are anaerobic, nonmotile, and do not form spores. The G + C content is in the range of 43.4–66.3% for the known species. The species of this family form a distinct clade in phylogenetic trees based on 16S rRNA gene sequences and sequences for different datasets of proteins from genomes. Additionally, the members of the family Eggerthellaceae (order Eggerthellales ) can be reliably distinguished from members of the order Coriobacteriales and other bacteria based on molecular signatures consisting of conserved indels (inserts or deletions) identified in >12 proteins described in earlier work and updated here. DNA G + C content (mol%) : 43.4–66.3 (for the known species). Type genus : Eggerthella Wade et al. 1999 VP emend. Würdemann et al. 2009. Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the family Eggerthellaceae is: correct name (last update, April 2026) * . LPSN classification: Bacteria / Bacillati / Actinomycetota / Coriobacteriia / Eggerthellales / Eggerthellaceae The family Eggerthellaceae can also be recovered in the Genome Taxonomy Database (GTDB) as f__Eggerthellaceae (version v232) ** . GTDB classification: d__Bacteria / p__Actinomycetota / c__Coriobacteriia / o__Coriobacteriales / f__Eggerthellaceae * Freese , H.M. , Meier‐Kolthoff , J.P. , Sardà Carbasse , J. , Afolayan , A.O.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
