Minocycline treatment for acute cervical spinal cord injury in females rats: microbiota composition
Bibliographic record
Abstract
STUDY PURPOSE: Minocycline has been widely studied for its local anti-inflammatory properties; however little is known about its antibiotic and systemic immune effects following spinal cord injury (SCI). The aim of the present study is to elucidate multiple system-wide changes involving the microbiota-immune axis induced by minocycline treatment in a rodent model of cervical contusion SCI (unilateral contusion 125 kdyns at an angle of 15 degrees to the right at C5). This study included 4 groups of adult female Lewis rats: uninjured n=10, uninjured + minocycline n=10, SCI n=8, SCI + minocycline n=9. Minocycline (or sterile water for untreated control groups) was administered at a dose of 50mg/kg via oral gavage for 7 days immediately following injury. DATA COLLECTED: fecal microbiota data: 16s rRNA sequencing data (at the phylum, class, order, family, genus and species taxonomic levels) from fecal samples collected before injury, on the day of injury, 5, 14 and 28 days post injury PRIMARY CONCLUSION: The present data shows that 7 days of minocycline treatment had a drastic acute effect on the microbiota composition regardless of whether the animal was uninjured or had a SCI. Later effects of SCI vs. uninjured rats emerged by 28 days post-SCI.

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.
