Brucellosis is a bacterial infection caused by the Brucella canis bacteria that primarily affects dogs, although it can also be transmitted to other animals and humans. It is a significant concern for dog breeders and owners as it can lead to infertility, abortions, and other reproductive problems. Therefore, brucellosis testing in canines is an essential aspect of managing dog populations, and the Brucellosis SNAP test is a commonly used method for screening dogs.
The Brucellosis SNAP test is a rapid and easy-to-perform test that provides results in just 10 minutes. The test works by detecting antibodies to the Brucella canis bacteria in a dog's serum or plasma. The SNAP test is based on the enzyme-linked immunosorbent assay (ELISA) principle, and it is highly sensitive and specific, with a reported sensitivity of 99.2% and a specificity of 99.9%.
The Brucellosis SNAP test is performed using a small amount of canine serum or plasma which is easily obtained by the centrifuge method. The device contains an antigen that reacts with the antibodies in the serum or plasma, causing a color change. The color change is then compared to a color chart provided with the test to determine whether the dog has been exposed to the Brucella canis bacteria.
It is important to note that a false-positive results can occur with the SNAP test, particularly in dogs that have been vaccinated against Brucella canis or have been exposed to other strains of the Brucella bacteria.
