Brucellosis causes abortions after the fifth month of pregnancy in cattle. An epidemic situation could destroy us. However, my main concern about brucellosis is it is a human disease. The incubation period runs anywhere from five days to several months. Onset can be sudden and acute, with chills and fever, severe headache, pains, malaise and occasional diarrhea.
Symptoms also can show up slowly, with mild malaise, pain in the muscles, head and back of the neck.
The fever's undulation can cause a spike of 104 or 105 degrees in the evening, with normal or subnormal temperatures and profuse sweating by morning. Symptoms may extend from 10-14 days in mild cases and from four to six months in acute ones. Since 1934, the battle against Brucellosis began, more as an effort to control the human vector, undulant fever, and cattlemen have voluntarily vaccinated their young female replacement cattle each year to help eradicate the disease at their own expense. More than 6,000 people were infected with the disease in 1947. In 1954 more than 100,000 cattle herds in the United States were infected.
