an infectious disease caused by bacteria of the genus
species have been shown to infect sheep, goats, cattle, deer,
elk, pigs, dogs, and several other animal species. Humans can
become infected when they contact these infected animals or
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 fatigue.
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 the bacteria.
brucellosis has routinely been by culture detection of the
bacteria, but culture has very low sensitivity and so is less
useful for 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
