The opsonic activity of bovine milk whey for the phagocytosis and killing by neutrophils of encapsulated and non-encapsulated Escherichia coli
Abstract
Encapsulated strains of Escherichia coli were found to be more resistant to phagocytosis and killing by bovine neutrophils; requiring in the order of 100 times more serum opsonins than non-encapsulated strains. Mid-lactation pooled whey from cows with no history of mastitis was opsonic for non-encapsulated strains, but had no effect on encapsulated organisms. In contrast, early lactation pooled whey (5-10 days post-partum) was opsonic for all strains of E. coli. It is concluded that since early lactation milk contains sufficient opsonins, severe E. coli mastitis at this stage of lactation is not due to opsonic deficiency.

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.
