Equine brucellosis is caused by Brucellaabortus and most commonly manifests as fistulous withers in horses, which can be a source of exposure to humans. Clinically, brucellosis may also be associated with poll evil, nonspecific lameness due to joint infection or, rarely, late abortions in mares.
How do horses get brucellosis?
Brucellosis is an uncommon infection in horses. Two strains of the bacteria, namely Brucella abortus(bovine) and Brucella suis (porcine), are responsible for equine infections. Infection is thought to be caused by direct contact with infected cattle or by ingesting contaminated feed.
What does brucellosis do to animals?
How does brucellosis affect my animal? Brucellosis causes reproductive problems (e.g. abortions, stillbirth, infertility) in most species of animals. Other signs can include arthritis in cows and pigs, mastitis and lameness in goats, and oozing skin lesions in horses (“fistulous withers”).
What is brucellosis and what causes it?
Brucellosis is a bacterial infection that spreads from animals to people. Most commonly, people are infected by eating raw or unpasteurized dairy products. Sometimes, the bacteria that cause brucellosis can spread through the air or through direct contact with infected animals.
How does brucellosis affect the body?
Brucellosis is a disease, caused by bacteria, which affects many different kinds of animals – including sheep, goats, cattle, deer, elk, pigs, and dogs. However, it can also cause a disease with flu-like symptoms in humans. People with brucellosis may develop fever, sweats, headaches, back pains, and physical weakness.
Is brucellosis a virus?
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.
How contagious is brucellosis?
Person-to-person spread of brucellosis is extremely rare. Infected mothers who are breast-feeding may transmit the infection to their infants. Sexual transmission has been rarely reported. While uncommon, transmission may also occur via tissue transplantation or blood transfusions.
What is the best treatment for brucellosis?
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.
Can brucellosis go away on its own?
Brucellosis goes away on its own in most people. Some health problems can linger.
How long does brucellosis last?
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.
How is brucellosis treated in humans?
Two-drug regimen consisting of streptomycin and doxycycline (streptomycin for 2 to 3 weeks and doxycycline for 8 weeks) or gentamicin plus doxycycline (gentamicin for 5-7 days and doxycycline for 8 weeks) should be recommended as the treatment of choice for uncomplicated brucellosis.
How common is brucellosis in humans?
Human brucellosis is a disease that is found worldwide, and it has an annual occurrence rate of more than 500,000 cases. Brucellosis tends to occur more commonly in regions with less established animal disease control programs and in areas where public-health initiatives may be less effective.
How do you test for brucellosis in humans?
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: X-rays. X-rays can reveal changes in your bones and joints.
Can brucellosis be prevented?
Brucellosis is preventable. To lower your chances of getting it, you’re encouraged to do the following: Avoid consuming raw meat or unpasteurized milk, cheese, and ice cream. Wear gloves and protective glasses when handling animals or animal tissues.
How is brucellosis controlled?
The most rational approach for preventing human brucellosis is the control and elimination of the infection in animals. Pasteurization of milk is another protective mechanism. Vaccination of cattle is recommended for control of bovine brucellosis in enzootic areas with high prevalence rates.
Can Rifampinin treat brucellosis?
Rifampin, which exhibits good intracellular diffusion and in vitro bactericidal activity on brucella, is effective in experimental brucellosis in mice, without selection of resistant strains.
