This disease is normally caused by Brucella abortus. It will result in abortions or still births. Diagnosis is by tests on fetuses and blood samples from involved females.
There is no trreatment, but animals with positive blood tests would be pelted.
This bacteria also causes Bang’s Disease or contagious abortion in cattle. This disease level is very low in the Maritimes, but is higher in Ontario. Infected cattle or any aborted fetuses should not be fed for this reason.
