Brucellosis is an infectious disease caused by the bacteria of the genus Brucella. These bacteria are primarily passed among animals, and they cause disease in many different vertebrates. Various Brucella species affect sheep, goats, cattle, deer, elk, pigs, dogs, and several other animals. Humans become infected by coming in contact with animals or animal products that are contaminated with these bacteria.

Brucellosis is not very common in the United States, where100 to 200 cases occur each year. But brucellosis can be very common in countries where animal disease control programs have not reduced the amount of disease among animals.

Brucellosis is diagnosed in a laboratory by finding Brucella organisms in samples of blood or bone marrow. Also, blood tests can be done to detect antibodies against the bacteria. If this method is used, two blood samples should be collected 2 weeks apart.

Yes, but treatment can be difficult. Doctors can prescribe effective antibiotics. Usually, doxycycline and rifampin are used in combination for 6 weeks to prevent reoccuring infection. Depending on the timing of treatment and severity of illness, recovery may take a few weeks to several months. Mortality is low (<2%), and is usually associated with endocarditis. These are live vaccines, and strain 19 is known to cause disease in humans.

Nobody knows. Like many disabled people (but unlike typical sufferers from those diseases) she was a very productive worker, even when she was too ill to leave her bed. She must have suffered from Post-Traumatic Stress Disorder (PTSD), because of her terrible experiences of the war. This would have contributed to her disability.

Direct person-to-person spread of brucellosis is extremely rare. Mothers who are breast-feeding may transmit the infection to their infants. Sexual transmission has also been reported. For both sexual and breast-feeding transmission, if the infant or person at risk is treated for brucellosis, their risk of becoming infected will probably be eliminated within 3 days. Although uncommon, transmission may also occur via contaminated tissue transplantation.

B. canis is the species of Brucella species that can infect dogs. This species has occasionally been transmitted to humans, but the vast majority of dog infections do not result in human illness. Although veterinarians exposed to blood of infected animals are at risk, pet owners are not considered to be at risk for infection. This is partly because it is unlikely that they will come in contact with blood, semen, or placenta of the dog.

Humans are generally infected in one of three ways: eating or drinking something that is contaminated with Brucella, breathing in the organism (inhalation), or having the bacteria enter the body through skin wounds. The most common way to be infected is by eating or drinking contaminated milk products. When sheep, goats, cows, or camels are infected, their milk is contaminated with the bacteria.

Although RB51 was developed as a less pathogenic strain, it does retain pathogenicity for humans so exposures can pose a human health risk. Post-exposure prophylaxis should therefore be considered for persons with RB51 exposure. RB51 was derived by selection in rifampin-enriched media and is resistant to rifampin in vitro. Use of rifampin for post-exposure prophylaxis or treatment, a recommended choice for other pathogenic bacteria, will not be effective for RB51.

Note: PEP recommendations for B. abortus RB51 (attenuated vaccine strain) differ from those for fully pathogenic Brucella spp. As RB51 was derived by selection in rifampin-enriched media and is resistant to rifampin in vitro, the use of rifampin for PEP or treatment will not be effective for RB51. Post-exposure prophylaxis for those at high risk of exposure should include doxycycline 100 mg orally twice daily for at least 21 days.

The major sources of infection are reproductive (mainly fetal and placental) secretions and mammary secretions (milk) from infected animals. Brucellosis can be transmitted through ingestion of or contact with aborted fetuses and infected calves. Brucellosis can be transmitted from bull to cow through natural mating; however, this is very rare.

USGS scientists are collaborating with university, State, and Federal groups on a number of studies. Ecological studies focus on forage availability, habitat use, and bison population dynamics. Brucellosis research includes examining the risk of transmission of the disease from wildlife to cattle, identification of exposed animals in the field, and the safety of vaccines to wildlife species.

Have you not seen or do you just choose to ignore the fact that Brucellosis is NOT just in the Elk and Bison. The Mountain sheep have it as well as every living thing out there. The places you say have eradicated it don't have ELK feed lot breeding grounds, you can NOT be so sure that there still isn't Brucellosis in the other animals. In the State of Montana the law is 'You must fence to keep OUT' Not the other way around, that in itself works both ways For the rancher and For the wildlife.

In order to obtain a certification, one must have 2 complete negative herd tests 10 to 14 months apart. Your private veterinarian must complete the application after 2nd test.

Your seal will indicate your expiration date however, you have 60-days either side to get your animals brucellosis tested.

This depends on several different factors and each case is looked at on an individual basis. The Veterinary Officer dealing with your breakdown will be the person who can best advise you on this matter. In some cases the herd may be depopulated.

The main risk for humans to become infected with brucellosis is through contact with reproductive fluids - placental and fetal fluids - from infected animals. Although there is a possibility for brucellosis to be transmitted through milk or meat, the pasteurization of milk and the cooking of meat destroy the bacteria. Any infection risk in humans is primarily in people who work with cattle and are exposed to potentially infected fluids.

Currently there are no known infected cattle herds in Idaho. However, there are some infected elk in a small portion of eastern Idaho.

In rare instances, brucellosis can be transmitted to horses and other animals. These animals, however, cannot transmit the disease to other animals.
