Criibacterium bergeronii gen. nov., sp. nov., a new member of the family Peptostreptococcaceae, isolated from human clinical samples
Bibliographic record
Abstract
A rod-shaped, motile anaerobic bacterium, designated CCRI-22567 T , was isolated from a vaginal sample of a woman diagnosed with bacterial vaginosis and subjected to a polyphasic taxonomic study. The novel strain was capable of growth at 30–42 °C (optimum, 42 °C), at pH 5.5–8.5 (optimum, pH 7.0–7.5) and in the presence of 0–1.5 % (w/v) NaCl (optimally at 0.5 % NaCl). The phylogenetic trees based on 16S rRNA gene sequences showed that strain CCRI-22567 T forms a distinct evolutionary lineage independent of other taxa in the family Peptostreptococcaceae . Strain CCRI-22567 T exhibited 90.1 % 16S rRNA gene sequence similarity to Peptoanaerobacter stomatis ACC19a T and 89.7 % to Eubacterium yurii subsp. schtitka ATCC 43716. The three closest organisms with an available whole genome were compared to strain CCRI-22567 T for genomic relatedness assessment. The genomic average nucleotide identities (OrthoANIu) obtained with Peptoanaerobacter stomatis ACC19a T , Eubacterium yurii subsp. margaretiae ATCC 43715 and Filifactor alocis ATCC 35896 T were 71.8, 70.3 and 69.6 %, respectively. Strain CCRI-22567 T contained C 18 : 1 ω9 c and C 18 : 1 ω9 c DMA as the major fatty acids. The DNA G+C content of strain CCRI-22567 T based on its genome sequence was 33.8 mol%. On the basis of the phylogenetic, chemotaxonomic and other phenotypic properties, strain CCRI-22567 T is considered to represent a new genus and species within the family Peptostreptococcaceae , for which the name Criibacterium bergeronii gen. nov., sp. nov., is proposed. The type strain of Criibacterium bergeronii is CCRI-22567 T (=LMG 31278 T =DSM 107614 T =CCUG 72594 T ).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
