Brucellosis is an infectious disease caused by bacteria. People can get the disease when they are in contact with infected animals or animal products contaminated with the bacteria. Animals that are most commonly infected include sheep, cattle, goats, pigs, and dogs, among others.
People with brucellosis may develop fever, sweats, headaches, back pains, and physical weakness. In severe cases, the central nervous system and the lining of the heart may be affected. One form of the illness may also cause long-lasting symptoms, including recurrent fevers, joint pain, and fatigue.
Brucellosis can spread from dogs to people through contact with an infected dog's birthing fluids and vaginal discharge while birthing puppies. This is why dog breeders and veterinarians are at higher risk.
Signs and symptoms of brucellosis may include fever, joint pain and fatigue. The infection can usually be treated with antibiotics. However, treatment takes several weeks to months, and the infection can recur.
It is not found in Australia but occurs in many overseas countries, particularly in the Mediterranean, Middle East, Central Asia and Central America. Brucella abortus usually infects cattle. Bovine brucellosis (brucellosis in cattle) has been eradicated from all states of Australia, including NSW, since 1989.
People who work with animals and are in contact with blood, placenta, foetuses and uterine secretions have an increased risk of contracting the disease. This method of transmission primarily affects farmers, butchers, hunters, veterinarians and laboratory personnel.

Symptoms and Signs of Brucellosis
Onset may be sudden, with chills and fever, severe headache, joint and low back pain, malaise, and occasionally diarrhea. Or onset may be insidious, with mild prodromal malaise, muscle pain, headache, and pain in the back of the neck, followed by a rise in evening temperature.
Brucellosis can be diagnosed in a laboratory by finding bacteria in samples of blood, bone marrow or other bodily fluids. Serological tests can also be done to detect antibodies against the bacteria.
The symptoms usually improve and are completely gone within about two to six months. However, the prognosis is poor in people who develop organ changes or complications such as heart damage, neurological, or genitourinary problems caused by chronic Brucella infection.
Brucellosis affects males and females in equal numbers. The disorder is rare in the United States since pasteurization of milk is routine and cattle are vaccinated against this disease. Fewer than 100 new cases are reported each year in the United States.
Clinical Signs in Dogs
Infected male dogs may have abnormally sized testicles (swollen or shrunken). Other signs observed with canine brucellosis include infertility, anorexia, weight loss, pain, lameness, incoordination, swollen lymph nodes, and muscle weakness.
Generally speaking, the STIs (sexually transmitted infections) we associate with person-to-person sexual contact, including HIV, cannot be transmitted through sexual contact between humans and animals because these infections are species-specific.
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.
Brucellosis is an infectious disease caused by Brucella species. It is known by many other names, including remitting fever, undulant fever, Mediterranean fever, Maltese fever, Gibraltar fever, Crimean fever, goat fever, and Bang disease.
Overall, three (9.38%) patients had known risk factors for tuberculosis, while six (18.75%) had risk factors for brucellosis. Conclusions: There is a clear overlap between brucellosis and tuberculosis both in terms of clinical presentation and laboratory parameters.
Soil: Brucella is persistent in soil for up to 125 days. Decon precautions should be taken. Water: Brucella is a probable water threat because the bacteria are stable for 20-72 days Other: Brucella spp. are naturally occurring & endemic in the United States.
Since person-to-person transmission is rare, patients do not have to be held in isolation rooms. Healthcare workers should exercise standard precautions. Laboratory workers should take necessary precautions when working with Brucella species.
Brucellosis is a reportable condition in all states and territories. Brucellosis cases must be reported to jurisdictions when identified by a healthcare provider, hospital, or laboratory.
For simple infections, doxycycline (100 mg PO twice daily for 6 weeks) may be the most appropriate monotherapy; however, relapse rates with such monotherapy approach 40% and as a result, rifampin (600-900 mg/day) is usually added.
Unpasteurized milk and cheese, as well as raw meat, can carry Brucella bacteria. Your chances of getting brucellosis are higher if you eat raw dairy or meat products from areas of the world where the disease is more common, such as Asia, Africa, and many parts of Europe.
Lethality: Brucellosis has a very low mortality rate, less than 5% of untreated cases, with most deaths caused by endocarditis or meningitis.
It was later named for British army physician David Bruce, who in 1887 first isolated and identified the causative bacteria, Brucella, from the spleen of a soldier who had died from the infection.
Although brucellosis can be found worldwide, it is more common in countries that do not have effective public health and domestic animal health programs. Areas currently listed as high risk are: the Mediterranean Basin (Portugal, Spain, Southern France, Italy, Greece, Turkey, North Africa)
