Antibiotics Effects in a Rabbit Model of<i>Chlamydia pneumoniae–</i>Induced Atherosclerosis
Bibliographic record
Abstract
The association of Chlamydia pneumoniae infection with the complications of atherosclerosis, cardiovascular disease, and stroke are well established. C. pneumoniae infection of New Zealand White rabbit respiratory tract can result in early changes of atherosclerosis of the aorta that are not produced by sham infection or by Mycoplasma pneumoniae (which result in similar lung pathology). Early institution of antimicrobials with antichlamydial activity (azithromycin, clarithromycin, moxifloxacin, and doxycycline) within 5 days of infection can largely prevent the aortic lesions (75%-85% efficacy). Early treatment is also effective in suppressing the IgG antibody response to C. pneumoniae. However, delayed treatment (6 weeks after infection) with azithromycin was ineffective in aborting vascular changes but clarithromycin was partially effective (62.5% reduction). These studies support but do not prove that C. pneumoniae can cause atherosclerosis. Antibiotics are potentially useful in this model, but the optimum dose and duration of therapy or use of combination of agents remain to be determined.

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.
