Antibodies to Capsular Polysaccharides of Group B Streptococcus in Pregnant Canadian Women: Relationship to Colonization Status and Infection
Bibliographic record
Abstract
Canada, the serotype distributions of vaginal-rectal group B Streptococcus (GBS) isolates were compared with all isolates from neonates with invasive GBS disease identified by population-based surveillance. Serum con-centrations of Ia, Ib, II, III, and V capsular polysaccharide (CPS)–specific IgG also were determined, according to serotype of the vaginal-rectal colonizing GBS strain. GBS coloni-zation was detected in 19.5 % (235 of 1207) of women. Serotype III accounted for 20.6 % (48 of 233) of colonizing strains available for typing but for 37 % (27 of 73) of invasive isolates from neonates (). Maternal colonization with type III was least likely to be associatedP!.01 with moderate concentrations of III CPS–specific IgG. Serotype III GBS is more invasive than other serotypes in this population; this may be due, at least in part, to poor maternal type III CPS–specific antibody response. Group B Streptococcus (GBS) is an important cause of in-vasive infection in humans, especially in infants!3 months old [1]. On the basis of information from an active population-based surveillance in the United States, 115,000 cases and 11300

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.
