(undulant fever, Bang's disease)

Brucellosis is a bacterial disease that may affect various organs of the body, producing a wide variety of signs and symptoms such as intermittent fever of variable duration, headache, weakness, swollen lymph nodes, profuse sweating, chills, weight loss and generalized aching. Brucellosis can also cause infection and inflammation of the bone, testicles, and the lining of the heart.

The disease is generally transmitted from infected animals (cattle, goats, pigs, and dogs) to humans and occurs more commonly outside the USA and Canada. Wisconsin averages only about one to two cases per year. Although everyone is susceptible and may get the disease if exposed to the Brucella bacteria, brucellosis occurs most commonly in people who work with livestock or in slaughterhouses, or who consume unpasteurized dairy products. The consumption of raw milk cheese from Mexico is a well recognized risk factor. Occasionally, persons who work in bacteriology laboratories can get exposed to the bacteria.
