Human Serum Activities against Hemophilus influenzae, Type b

Abstract

Humoral immunity to Hemophilus influenzae, type b was studied in normal human adults by means of assays for serum bactericidal and opsonizing activities against the organism and for passive hemagglutinating activity using erythrocytes sensitized with polyribophosphate, the type-specific capsular antigen. Hemagglutinating activity was detectable in about 60% of the 114 sera tested. Serum bactericidal and opsonizing activities were found in all sera tested; the levels in some sera, however, were quite low. The antibacterial activities were due not only to antibodies directed against the polyribophosphate capsule but also to antibodies that appear to be directed against somatic antigens. Type b strains differed in their susceptibility to the antisomatic antibodies of particular sera but were uniformly sensitive to anticapsular antibody.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
