Inflammation of the inner lining of the heart chambers (endocarditis). This is one of the most serious complications of brucellosis. Untreated endocarditis can damage or destroy the heart valves and is the leading cause of brucellosis-related deaths.
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.
Generally, the antibiotics doxycycline and rifampin are recommended in combination for a minimum of 6-8 weeks.
Animals that are most commonly infected include sheep, cattle, goats, pigs, and dogs, among others. Brucellosis in the U.S.
Brucellosis is a bacterial disease caused by various Brucella species, which mainly infect cattle, swine, goats, sheep and dogs. Humans generally acquire the disease through direct contact with infected animals, by eating or drinking contaminated animal products or by inhaling airborne agents.
Brucellosis can also cause long-lasting or chronic symptoms such as recurrent fevers, joint pain, testicular swelling, heart infections, nervous system impairment, depression, and fatigue. Death from brucellosis is rare.
Brucellosis can affect almost any part of your body, including your reproductive system, liver, heart and central nervous system. Chronic brucellosis may cause complications in just one organ or throughout your body. Possible complications include: Inflammation of the inner lining of the heart chambers (endocarditis).
The natural invasion of the host by Brucella induces a specific immune response mediated by Th1 lymphocytes that protects against the development of the disease, similar to the one observed in infections caused by other intracellular pathogens as Salmonella and Mycobacterium tuberculosis.
Brucellosis is a zoonotic disease that severely hinders livestock productivity and human health worldwide. The burden that the disease places specifically on low-income countries has led the World Health Organization (WHO) to classify it as one of the world's leading 'neglected zoonotic diseases' [1].
Brucellosis infection of the central nervous system (CNS) is a rare but severe complication [2, 3] and the varied clinical manifestations, including confusion, meningoencephalitis, myelitis, peripheral or cranial neuropathies, and psychiatric manifestations, make the diagnosis challenging.
Lethality: Brucellosis has a very low mortality rate, less than 5% of untreated cases, with most deaths caused by endocarditis or meningitis. Transmissibility: Person-to-person transmission of brucellosis is extremely rare.
Canine Brucellosis is a disease found in dogs and caused by the bacterium, Brucella canis. Infected dogs can also spread the disease to people.
Yes, Brucella infections in humans can be cured by antibiotics. However, some complications can cause lasting damage.
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.
Brucellosis, also known as “undulant fever”, “Mediterranean fever” or “Malta fever” is a zoonosis and the infection is almost invariably transmitted by direct or indirect contact with infected animals or their products. It affects people of all age groups and of both sexes.
Clinical Presentation
Focal infections are common and can affect most organs in the body. Osteoarticular involvement is the most common brucellosis complication, as is reproductive system involvement. Although rare, endocarditis can occur and is the principal cause of death among patients with brucellosis.
There are a reported 500,000 incident cases of human brucellosis per year. However, true incidence is estimated to be 5,000,000 to 12,500,000 cases annually.
Public Health Significance of Brucellosis
Brucella abortus causes serious zoonotic disease and is an invasive Brucella species in humans. Occupational contact is seen in people who have interacted with infected cattle or their tissues. Brucella infection is among the principal easily acquired laboratory infections.
In addition, Brucella uses multiple strategies such as cloaking to avoid recognition by the autophagy mechanism and development of replicative niches. Furthermore, inhibition of apoptosis is another strategy of Brucella to evade the immune response to establish chronic infection.
Brucellosis is a zoonotic disease caused by a Gram-negative bacillus of the Brucella genus with multisystem involvement, primarily affecting the reticuloendothelial system, joints, heart and kidneys. Although the disease can be spread by inhalation, pulmonary involvement is rare.
Brucella can survive for months in the environment under optimum conditions but can be destroyed by heat and some disinfectants. Thoroughly clean and disinfect areas exposed to infected animals, their urine, blood, milk, or discharges. Keep sick animals away from other animals to avoid spreading the disease.
Neurobrucellosis occurs in 5%–10% of patients with brucellosis (4). The most frequent clinical manifestation is meningoencephalitis (5). Mass lesions in the brain are uncommon (4).
Four main clinical patterns of skin lesions associated with brucellosis have been described, including disseminated papulonodular eruption, diffuse maculopapular rash, and erythema nodosum-like and purpuric lesions.
Sensory conduction velocities of the median (p < 0.001), ulnar and sural (p < 0.05) nerve were also decreased. Brucellosis may be considered as a cause of clinical or subclinical peripheral neuropathy and should be evaluated especially in endemic areas.
Brucellosis is caused by Brucella species, which are gram-negative bacteria. Symptoms begin as an acute febrile illness with few or no localized signs and may progress to a chronic stage with relapses of fever, weakness, sweats, and vague aches and pains. Diagnosis is by culture, usually from the blood.
