How is brucellosis identified?

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. There is no serological test available to detect antibodies to B.

Is Brucella oxidase positive or negative?

Brucella is non-motile and generally oxidase-positive and urease-positive [6].

Is Brucella canis Gram positive or negative?

gram-negative bacterium
Brucella canis is a gram-negative bacterium in the family Brucellaceae that causes brucellosis in dogs and other canids. B. canis is rod-shaped or a coccus, and is oxidase, catalase, and urease positive. The species was firstly described in United States in 1966 where mass abortions of beagles were documented.

What is Wright test for Brucella?

In Wright’s serotype reaction, specific Brucella antigens are mixed with the patient’s serum and a welding reaction is sought. A positive reaction is followed by successive dilutions of serum and re-testing. The results are expressed as the highest titre indicating welding.

What is the difference between Brucella and brucellosis?

Brucellosis is a severe acute febrile disease caused by bacteria of the genus Brucella. Relapses are not uncommon; focal lesions may occur in bones, joints, genitourinary tract, and other sites. Hypersensitivity reactions can follow occupational exposure. Infection may be subclinical.

Is Brucella indole positive?

Although Brucella is a strict aerobe, some strains require carbon dioxide, especially on primary isolation. Brucella is non-motile and generally oxidase-positive and urease-positive [6].

Does Brucella grow on MacConkey?

Brucella & Pasteurella. MacConkey: MacConkey agar is a selective medium that inhibits the growth of Gram-positive bateria due to the presence of crystal violet and bile salts. Most Gram-negative bacteria grow well on MacConkey.

How is Brucella canis treated?

In dogs. Brucellosis is very difficult to treat and relapses are common. Treatment includes spaying or neutering, giving antibiotics for several months, and frequent blood tests to monitor treatment progress.
