THE TRANSMISSION OF AGGLUTININS OF BACILLUS ABORTUS FROM COW TO CALF IN THE COLOSTRUM.
The agglutinins towards Bacillus abortus found in the blood serum of new-born calves are obtained from the mother through the colostrum. Calves at birth, unfed, are without agglutinins. The problem of the production of agglutinins by the fetus in whose tissues Bacillus abortus has multiplied and which is subsequently expelled prematurely is not touched by these observations.
