Prevalence of<i>Malassezia</i>species on various body sites in clinically healthy subjects representing different age groups
Bibliographic record
Abstract
To investigate the distribution of Malassezia species on four body sites (scalp, forehead, chest and back), we employed contact plates filled with Leeming-Notman agar to sample 245 clinically healthy subjects, representing six age groups (AG) (AG I, 0-3 years; AG II, 4 14 years; AG III, 15-25 years; AG IV, 26-40 years; AG V, 41-60 years; AG VI, over 60 years). The number of colony forming units was recorded for every plate positive for Malassezia species, and the species were identified. Younger individuals (< 14 years) yielded a culture positive for Malassezia significantly less frequently than did older individuals (> or = 15 years). M. globosa was cultured at significantly elevated frequency on younger subjects. M. sympodialis was present at low frequency on younger subjects, but was found in higher amounts on the skin of adolescents and adults. The amount and kind of Malassezia species that can be recovered from human skin varies with age and body site.
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.

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.
