Assignment of provisionally named CDC group NO-1 strains derived from animal bite wounds and other clinical sources, to genera nova in the family Comamonadaceae: description of Vandammella animalimorsus gen. nov., sp. nov. and Franklinella schreckenbergeri gen. nov., sp. nov
Bibliographic record
Abstract
CDC group non-oxidizer (NO)-1 is the provisional name designated in 1993 for phenotypically similar, Gram-stain-negative bacilli recovered primarily from human wound infections after animal bites. Otherwise, this group has been rarely alluded to in recent literature. CDC NO-1 strains had been described as non-motile, asaccharolytic, oxidase-negative, catalase-positive, nitrate-reducing bacilli, with predominate cellular fatty acids of C 10 : 0 3OH, C 16 : 1 ω7 c , C 16 : 0 and C 18 : 1 ω7 c . Only one 16S rRNA gene sequence deposited in NCBI (accession no. DQ054782) had been identified as CDC group NO-1 prior to this study. That sequence was closely related (>99 % identity) to sequences called ‘ Xenophilus species’ from canine (JN713339) and feline (KM461961) oral microbiomes as well as to sequences derived from human strains (this study). Some of the 11 isolates delineated here were recovered from human wound infections subsequent to cat/dog bites; others were from wounds (links to animal bites not described) and two were recovered from dialysates. After 16S rRNA and whole genome sequencing, the isolates were found to be most closely related to each other but fell into two distinct genera assignable to the family Comamonadaceae , provisionally discussed here as CDC group NO-1 and CDC group NO-1-like. The genomes of CDC group NO-1 isolates ranged from 3.08 to 3.38 MB with G+C contents of 65.08–66.92 %; genomes derived from CDC group NO-1-like strains were smaller, ranging from 2.72 to 2.82 Mb with G+C contents of 62.87–63.0 mol%. Based on a polyphasic study of these bacteria, we describe Vandammella animalimorsus gen. nov., sp. nov. and Franklinella schreckenbergeri gen. nov., sp. nov. for these clusters.

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.
