THE RELATION BETWEEN THE ACCUMULATION OF GLOBULINS AND THE APPEARANCE OF AGGLUTININS IN THE BLOOD OF NEW-BORN CALVES
1Department of Animal Pathology of The Rockefeller Institute for Medical Research, Princeton, N.J.
Abstract:
A comparison of the appearance of the agglutinins for Bacillus abortus in the blood of new-born calves with the first appearance of globulins in the same blood following the ingestion of colostrum indicates that the agglutinins are associated with the globulins. These observations are supported by the removal of the agglutinins from serum or colostrum with concentrations of sodium sulfate which precipitate globulins present in the blood of calves which have ingested colostrum, but which are not present at birth. Neither the association of immune bodies with globulins nor the direct absorption of protein by new-born animals is a new fact. The evidence presented is of particular value, however, in associating the appearance of certain protein fractions in the blood of the new-born animal with the simultaneous absorption of agglutinins.

Transcytosis of IgG
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
