Abstract
The transmission of anti-Brucella agglutinins to the young from mothers immunized during pregnancy, and from mothers immunized before and during pregnancy was studied. There is no significant transfer of anti-Brucella agglutinins before birth, and the post-natal transfer of these antibodies is of a very low order. The highest concentration obtained in the sera of suckling young was only 3% of that in the maternal sera. At parturition the titre of the milk is of the same order as that of the maternal serum, but with suckling it declines to about 25% of the maternal serum titre.
