A Case of Fulminant <i>Bacillus cereus</i> Lung Necrosis in a Preterm Neonate
Bibliographic record
Abstract
Bacillus cereus is a ubiquitous Gram-positive rod seldom considered pathogenic in clinical isolates. However, it possesses multiple virulence factors explaining why it has been linked to fulminant and pyogenic infections in vulnerable hosts. Its recovery from sterile samples in immunocompromised patients cannot be disregarded. Premature infants would fall into this category. We describe the case of a neonate born at 26 weeks of gestational age, who died of a rapidly progressive B. cereus necrotizing pneumonia following suspected nosocomial acquisition. The rapidity of his course and the autopsy findings of necrosis with minimal inflammation suggest a toxin-mediated process. Pathologists should be aware of this pathogen and obtain proper microbiological samples in the presence of such autopsy findings, as the diagnosis may have infection-prevention implications in health-care settings.

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.
