is a major cause of canine infertility. It is primarily a sexually
transmitted disease, but can also be transmitted by contact with
infected bodily fluids. The disease can be passed from dogs to humans
In humans, brucellosis can cause a range of symptoms similar to
influenza, and may include fever, sweats, headaches, back pains, and
physical weakness. Severe infections of the central nervous system or
lining of the heart may occur. Brucellosis can also cause long-lasting
or chronic symptoms that include recurrent fevers, joint pain and
Although brucellosis is not common in United States, it frequently
occurs in countries that have poor animal disease control programs.
Travel to these countries can result in infection with these bacteria.
Humans are usually infected by eating or drinking something that is
contaminated with the bacteria, by inhaling the bacteria, or by
exposure of wounds to these bacteria. Occupational exposure is one of
the major routes for human infection. The chronic nature of the
disease means that infected people or animals can become carriers of
Diagnosis of brucellosis has traditionally been by culture detection
of the bacteria, but culture has very low sensitivity and so is less
useful for detection of subacute and chronic carriers. Molecular
detection by PCR, on the other hand, can provide rapid, sensitive and
specific identification of these bacteria in a sample (Mitka et al.,
