The RBT is the screening test in all species. Positive and inconclusive results are subsequently tested with the confirmatory complement fixation test (CFT). Negative RBT results, but with a strong clinical picture and history suggestive of B. suis infection will also be tested with the CFT.
A blood sample is tested for the antibodies that fight Brucella canis. If a dog tests positive for the antibodies on a screening test, another test is done to confirm. The tests are: Screening tests: Rapid Slide Agglutination Test (RSAT) and Tube Agglutination Test (TAT)
Brucellosis can be diagnosed in a laboratory by finding bacteria in samples of blood, bone marrow or other bodily fluids. Serological tests can also be done to detect antibodies against the bacteria.

Rapid turn-around time. Negative test results will typically be available within 1 business day.
Doctors usually confirm a diagnosis of brucellosis by testing blood or bone marrow for the brucella bacteria or by testing blood for antibodies to the bacteria. To help detect complications of brucellosis, your doctor may order additional tests, including: X-rays. X-rays can reveal changes in your bones and joints.
Signs and symptoms of brucellosis may include fever, joint pain and fatigue. The infection can usually be treated with antibiotics. However, treatment takes several weeks to months, and the infection can recur.
Brucellosis in dogs is a rare disease in Canada. It is more prevalent in some areas of the United States, such as the southern USA, and in other parts of the world.
2) Identification of Infected Puppies: All puppies born to infected dams or puppies less than 6 weeks of age at the time of initial screening must have 3 negative blood cultures at least 24 hours apart or be euthanized. Puppies with a positive blood culture should be euthanized.
Euthanasia of infected animals is recommended in kennels, and should also be considered in pets, since treatment is often expensive and unsuccessful. There is no vaccine available to prevent canine brucellosis in dogs or in people.
What are the signs of brucellosis? There is no effective way to detect infected animals by their appearance. The most obvious signs in pregnant animals are abortion or birth of weak calves. Milk production may be reduced from changes in the normal lactation period caused by abortions and delayed conceptions.
How serious is brucellosis? Considering the damage done by the infection in animals-decreased milk production, weight loss in animals, loss of young, infertility, and lameness, it is one of the most serious diseases of livestock.
However, it can also cause a disease with flu-like symptoms in humans. People with brucellosis may develop fever, sweats, headaches, back pains, and physical weakness. In severe cases, the central nervous system and the lining of the heart may be affected.
Death from brucellosis is rare, occurring in no more than 2% of all cases. Generally, the antibiotics doxycycline and rifampin are recommended in combination for a minimum of 6-8 weeks.
For simple infections, doxycycline (100 mg PO twice daily for 6 weeks) may be the most appropriate monotherapy; however, relapse rates with such monotherapy approach 40% and as a result, rifampin (600-900 mg/day) is usually added.
I have read estimates as high as 6% of dogs in the southeastern US are affected but this percentage includes stray/feral dogs. CHF: How are the Brucella bacteria transmitted from dog to dog?
Can brucellosis in animals be cured? No. Repeated attempts to develop a cure for brucellosis in animals have failed. Occasionally, animals may recover after a period of time.
Brucellosis is an infectious disease caused by bacteria. People can get the disease when they are in contact with infected animals or animal products contaminated with the bacteria. Animals that are most commonly infected include sheep, cattle, goats, pigs, and dogs, among others.
In addition to bacterial isolation, serological tests can be performed. CDC utilizes a test called the Brucella microagglutination test (BMAT), a modified version of the serum (tube) agglutination test (SAT), that can detect antibodies to Brucella species – abortus, melitensis or suis.
It is a serious disease that has been eradicated from most livestock in theUnited States (U.S.). The only remaining reservoir of infection in the U.S. is in elk and bison in the Greater Yellowstone Area, with regular spill-over of infection into livestock. It is still prevalent in cattle in Mexico.
Brucellosis caused by Brucella abortus, B. suis, or B. melitensis is relatively rare in dogs. In cases that do occur, the dogs are usually around livestock, as they are the primary source of those strains of the bacteria.
Signs of illness can occur within one week to several months after exposure. On average, signs and symptoms will begin within three to four weeks following infection.
While there are no vaccines for humans or dogs, several licensed live Brucella vaccines are available for use in livestock throughout the world, such as the B.
The best way to prevent brucellosis is to spay or neuter your dog according to your veterinarian's advice. Since breeding your dog should be a very well-considered decision, discuss with your veterinarian the potential consequences of breeding. Reducing the risk of exposing your favorite canine also reduces your risk.
Lethality: Brucellosis has a very low mortality rate, less than 5% of untreated cases, with most deaths caused by endocarditis or meningitis.
