Treatment. Before treatment begins, a diagnosis of brucellosis infection must be made by a doctor. Tests will be performed to look for bacteria in samples of blood, bone marrow, or other body fluids. In addition, a blood test can be performed to detect antibodies against the bacteria. Once a diagnosis is made, a doctor can prescribe antibiotics.

Depending on the timing of treatment and severity of illness, recovery may take a few weeks to several months. Death from brucellosis is rare, occurring in no more than 2% of all cases. Generally, the antibiotics doxycycline and rifampin are recommended in combination for a minimum of 6-8 weeks.
Diagnosis
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:
Treatment
Treatment for brucellosis aims to relieve symptoms, prevent a relapse of the disease and avoid complications. You'll need to take antibiotics for at least six weeks, and your symptoms may not go away completely for several months. The disease may also return and become chronic.
Preparing for your appointment
If you think you may have brucellosis, you're likely to start by seeing your family doctor or a general practitioner. You may be referred to an infectious disease specialist.

What is the cause of brucellosis?
Brucellosis Facts. Brucellosis is an infectious disease caused by bacteria from the genus Brucella. Brucellosis is an infection of certain animals that is transmitted to humans. Humans acquire brucellosis when they come in contact with contaminated animals or animal products, most commonly from the ingestion of raw milk or cheese.

The use of brucellosis for biological warfare purposes was later banned in 1969 by President Nixon.
How long does a Brucella abortus live?
Brucella abortus survived in a model system using sterilized milk and lactic acid for 34 days at a pH range of 5.0–5.8, but when the pH dropped to 3.9, the survival period decreased to only 2 days. The same species showed 90% survival after 3 h exposure to pH 3.8 and this dropped to only 60% survival after 24 h.

What is the disease of brucellosis?
Brucellosis is a disease occurring in cattle ( Brucella abortus ), dogs ( B. canis ), goats and sheep ( B. melitensis ), and pigs ( B. suis). Humans are affected mainly through ingestion of contaminated milk products, by contact, or by inhalation. Brucellosis (also known as relapsing, undulant, Malta, or Mediterranean fever) is a systemic bacterial disease of acute or insidious onset characterized by fever, headache, weakness, sweating, chills, arthralgia, depression, weight loss, and generalized malaise. Transmission can occur as a result of contact with tissues, blood, urine, vaginal discharges; however, brucellosis is predominantly spread by ingestion of raw milk and dairy products from infected animals. The disease may last from a few days to a year or more. Complications include osteoarthritis and relapses. Case fatality is under 2 percent, but disability is common and can be pronounced.
What are the proteins in the Brucella abortus genome?
Genome sequence analyses reveal that Brucella abortus genome encodes 10 proteins with predicted PAS domains, 8 are associated with histidine kinase domains and 2 are associated with GGDEF/EAL domains, among which 5 proteins (BAB1_0640, 1139, 1621, 2101, and 0220) are predicted to contain a haem as a prosthetic group though it is not proved experimentally (Carrica Mdel, Fernandez, Martí, Paris, & Goldbaum, 2012 ). NtrY (BAB1_1139) is the histidine kinase in the NtrY/NtrX two-component system found in Brucella spp. that are facultative intracellular gram-negative bacteria that belong to the α2 proteobacteria group. The expression of all the denitrification enzymes is increased in low O2 tension in these bacteria, which is partly triggered by the NtrY/NtrX two-component system ( Al Dahouk et al., 2009; Roop & Caswell, 2012 ). NtrY from B. abortus is a homologue to NtrY that is involved in nitrogen metabolism and/or fixation in Azorhizobium caulinodans and Azospirillum brasilense ( Ishida et al., 2002; Pawlowski, Klosse, & de Bruijn, 1991 ), which contains predicted transmembrane regions at the N-terminus followed by a HAMP, PAS, and histidine kinase domains ( Carrica Mdel et al., 2012). The PAS domain binds a haem, which shows the Soret, α, and β bands at 408, 558, and 533 nm, and 423, 555, and 527 nm in the ferric and ferrous states, respectively ( Carrica Mdel et al., 2012 ). While a stable O 2-bound NtrY does not form due to an autoxidation to produce the ferric form, NO and CO can bind to the ferrous haem in NtrY to form a 5-coordinate nitrosyl haem and 6-coordinate CO-bound haem, respectively (Carrica Mdel et al., 2012 ). Ferrous NtrY possesses much higher autokinase activity than ferric NtrY. The autokinase activity of CO-bound and NO-bound NtrY is similar to that of ferrous NtrY ( Carrica Mdel et al., 2012 ), though the coordination structures of the CO- and NO-bound haems are different from each other. The reason of this unique property is not obvious at present. Based on these results, it is proposed that NtrY acts as a redox sensor, not a gas sensor ( Carrica Mdel et al., 2012 ). Alignments of amino acid sequences among NtrY and other haem-containing PAS domains reveal that NtrY does not show a conserved His as the proximal haem ligand within its PAS domain, which suggests that the haem binds to the PAS domain in NtrY in a different manner to that described for other haem-containing PAS domains. However, more detailed characterisation with spectroscopic and structural methods is required to prove this hypothesis with identification of the coordination structure of the haem in NtrY.
How long does B. abortus stay in cheese?
