Skin Microbial Flora and Effectiveness of Aseptic Technique for Deep Muscle Biopsies in Weddell Seals (Leptonychotes weddellii ) in McMurdo Sound, Antarctica
Bibliographic record
Abstract
Deep muscle biopsies were collected from the pectoralis and longissimus dorsi of wild Weddell seals (Leptonychotes weddellii) in McMurdo Sound, Antarctica, during October-December 2007. Sterile swabs were collected from the surface of each skin site before biopsy and from the deep-needle path after biopsy. No growth occurred in two of six pectoralis and three of six longissimus skin sites, or in four of 10 pectoralis deep biopsy and eight of 12 longissimus deep-biopsy sites. Positive skin culture was not predictive of deep-biopsy contamination, nor did contamination at one body location correlate with contamination at the second site. Psychrobacter species were most common in one or more samples from each of the four sample types. Only one of the eight documented bacteria exhibited resistance to commonly used antibiotics.
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.
