Abstract
U.re.a.plas'ma. N.L. fem. n.ureaurea; Gr. neut. n.plasmaanything formed or moulded, image, figure; N.L. neut. n.Ureaplasmaurea form. Tenericutes / Mollicutes / Mycoplasmatales / Mycoplasmataceae / Ureaplasma Bacteria in the genusUreaplasmaare small (350–500 nm in diameter) coccoid cells, devoid of a cell wall, that form exceptionally tiny (<0.2 mm) colonies on solid media. Like the closely‐related genusMycoplasma, ureaplasmas have small (0.75–1.2 Mb) A+T‐rich genomes, use the codon UGA to encode tryptophan, and are nutritionally fastidious, but unlike mycoplasmas they hydrolyze urea rather than glucose or arginine for ATP synthesis. DNA–DNA hybridizations and serotyping involving a family of phase‐variable surface lipoproteins called multiple‐banded antigens have been important in developing the species concept for this genus. In nature all species are obligate commensals or opportunistic pathogens of vertebrate hosts. Based on the most recent comparative genome analyses, a consensus is emerging that the strains associated with humans, currently recognized as biovars of eitherUreaplasma urealyticumorUreaplasma parvum, probably exist collectively as quasi‐species rather than as stable serovars in their native environment.

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.
