Milk Ring Test. The test consists of mixing colored Brucella whole-cell antigen with fresh bulk/tank milk. In the presence of anti-Brucella antibodies, antigen-antibody complexes form and migrate to the cream layer, forming a purple ring on the surface.

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.

An abnormal (positive) result usually means you have come in contact with the bacteria that causes brucellosis or a closely related bacteria. However, this positive result does not mean that you have an active infection. Your provider will have you repeat the test after a few weeks to see if the test result increases.

Brucella abortus is a bacterium that causes brucellosis in cattle. B. abortus RB51 is a strain of this bacterium developed specifically for immunization of cattle against brucellosis to allow serological differentiation between naturally infected and vaccinated animals.

In order for bovine brucellosis surveillance to be effective, reliable diagnostic tests need to be used. Bacterial culture and identification is the gold standard for diagnosis of B. abortus (Morgan 1977; Nielsen 2002).

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.

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. One form of the illness may also cause long-lasting symptoms, including recurrent fevers, joint pain, and fatigue.
