Abstract:
An outbreak of brucellosis on a dairy farm and its subsequent treatment are documented. Brucellosis most often attacks fetal calves, killing them in utero and resulting in abortion. It spreads quickly among cows. In human beings, the disease is called undulant fever. When an animal is found to be infected, it is isolated from the herd. The aborted calf should be buried where it can not be dug up by dogs or other predators, and where it can not contaminate the soil. Lime should be spread on the calf's grave and on the spot where it was found dead. Tools, shoes, everything used in handling the calf should also be disinfected. All the cows in the herd must now be tested for brucellosis. All infected cows mustbe slaughtered as there is no cure for the disease. Remaining healthy cows are vaccinated with Strain 19 against the disease. The premises are thoroughly cleaned to get rid of remaining microorganisms.
