CONTAGIOUS ABORTION IN DAIRY COW S AND THE PRESENCE OF THE BACILLUS IN THE MILK By CHARLES EVANS, D.V.S. THE tagious presence abortion of the in bacillus the economy of con- of tagious abortion in the economy of ^ dairy cows and the dissemination of the germ by the milk, forms the subject of this paper. During the past twelve months, the. The existence of a specific contagious disease causing abor- tion in cows has been recognized for a long time, and it is certain that the disease known abroad as infectious or contagious abortion is also prevalent in the United States. 2. The infectious agent is a bacterium first described by the Danish investigators, Bang and Stribol.t. Every case of abortion should be regarded as of the contagious variety unless proved to be otherwise by sero-diagnostic tests. In badly infected herds every effort should be made in order that aborted cows may conceive again, so that an immune herd may be acquired eventually. Methods of vaccination have been introduced. Brucellosis in Cattle (Contagious abortion, Bang’s disease) BRUCELLA ABORTUS is a major cause of abortion worldwide but has been controlled in most parts of the world. In countries with a high incidence of bovine brucellosis B. MELITENSIS is sometimes isolated from cattle. Most abortions occur at months of gestation.
An important bacterial disease of cattle and buffalo. Leads to loss in milk production, loss of calf, birth of weak or diseased calf,repeat breeding and even mastitis. Humans may also get the disease from consumption of raw milk of infected animal or contact with uterine discharges. The disease is very much prevalent in India, both in humans and animals. In , Danish veterinarian Bernhard Bang isolated a bacillus as the agent of heightened spontaneous abortion in cows, and the name "Bang's disease" was assigned to this condition. At the time, no one knew that this bacillus had anything to do with the causative agent in Malta lty: Infectious disease. The cow recognizes the fetus as dead, so she aborts. Hanzlicek said mycotic abortions are often mistaken for other types of abortions. Most abortions in cattle occur in either the middle or last trimester, and mycotic abortions likewise typically occur around six to eight months of pregnancy.

Immunity to the serotype causing abortion but sensitive to . Mycotic (caused by mycotoxins) abortions may be seen in increased numbers in spring, due to cattle consuming moldy feed contaminated with mycotoxins. These abortions are typically sporadic and occur from four months to term. The germs of Contagious Abortion not only work on the diseased animals, but are found in the barns where diseased cattle have been housed, ready to attack every animal rendered susceptible to attack. They go farther back, and are found to affect calves dropped by cows infected with contagious abortion.
