title: Detection of brucella antigen in bovine fetal stomach contents by agar gel precipitation and counter-immunoelectrophoresis.
abstract: Among 21 fetuses from serologically positive dams soluble brucella antigen was detected in the stomach contents in 14 instances by agar gel precipitation test and in 19 by counterimmunoelectrophoresis. Brucella abortus biotype 3 was isolated from the fetal stomach contents in 15 of these cases. None of 20 fetuses from serologically negative dams revealed brucella antigen in the stomach contents in either test.
