Recurrent Late-Onset Group B <i>Streptococcus</i> Sepsis in a Preterm Infant Acquired by Expressed Breastmilk Transmission: A Case Report
Bibliographic record
Abstract
Group B Streptococcus is a known cause of neonatal sepsis, being more common in the early period by maternal genital tract transmission and less so in the late neonatal period, ascribed to intestinal colonization or horizontal transmission. Although breastmilk transmission of Group B Streptococcus has rarely been reported in the past, most cases are of patients nursed on the mother's breast and less commonly in expressed breastmilk-fed infants. This case describes a preterm infant (born at a gestational age of 24 weeks 6 days) in the neonatal intensive care unit who acquired recurrent late-onset sepsis with Group B Streptococcus with the mother's expressed breastmilk culture growing the same organism that was later matched to the infant's isolate. The mother had presented with features of mastitis only during the second episode of sepsis and was then treated with oral antibiotics. The infant was fed on formula feeds after the second incidence and remained healthy, being discharged on a regular follow-up plan at 39 weeks corrected gestational age.

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.
