One of the reasons why brucellosis still remains an elusive disease in humans concerns weaknesses in our understanding of the host–pathogen interaction. Recent methodological advances might possibly contribute to the identification of potential new targets for diagnosis, intervention and prevention of brucellosis.
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.
Brucella evades the host immune response by affecting macrophage function. Brucella can inhibit IFN-γ mediated phagocytosis and TNF-α expression in macrophages [51]. Infected macrophages can produce proinflammatory factors (TNF-α, IL-6, IL-12) and inflammatory chemokines (GRO-α, IL-8, MCP-1).
The disease is called undulant fever because the fever is typically undulant, rising and falling like a wave. It is also called brucellosis after its bacterial cause.
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.
Apart from well-known endemic regions, brucellosis remains a neglected disease in many areas worldwide which can lead to serious health and economic concern for the livestock populations by affecting animals such as cattle, buffalo, camel, sheep and goat (Sulima and Venkataraman 2010; Santos et al.
The brucellosis eradication program was designed as a cooperative effort between the federal government, the states, and livestock producers. National eradication in cattle was mostly achieved by the early 2000s, with now only an occasional spillover case in cattle in the GYA, but none elsewhere since 2010.
In cattle, brucellosis is called Bang's disease, after Bernhard Lauritz Frederik Bang, a Danish veterinarian, who discovered B. abortus as the cause of contagious abortion in cattle in 1887. In cows the organism causes disintegration of the placenta, leading to late-term abortion.
Worldwide, Brucella melitensis is the most prevalent species causing human brucellosis, owing in part to difficulties in immunizing free-ranging goats and sheep.
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.
One way in which an infectious agent can evade immune surveillance is by altering its antigens; this is particularly important for extracellular pathogens, against which the principal defense is the production of antibody against their surface structures.
Brucella spp. are facultative intracellular parasitic pathogens that can survive and multiply in professional and nonprofessional phagocytes.
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 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.
The disease we now know as brucellosis was first discovered in the 1850s in Malta. It came to the attention of British medical officers serving on the island after the Crimean War. It was easy to eliminate the disease in British servicemen, but very difficult to reach Maltese citizens.
Although vaccination of individuals living in brucellosis endemic areas, veterinarians, livestock, and laboratory personnel is essential, human vaccines have not yet been developed (9). Live-attenuated vaccines are the most effective vaccines used to control animal brucellosis (10).
Except for possible cases of transmission after blood transfusion, parenteral drug use and bone marrow transplant (1), brucellosis is still considered not to be transmissible from person to person via close contact (2).
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.
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].
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.
Bovine tuberculosis is a chronic bacterial disease (primarily of cattle) caused by the microorganism, Mycobacterium bovis. Brucellosis is a contagious, infectious, and communicable disease, primarily affecting cattle, bison, and swine, and is caused by bacteria of the genus Brucella.
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.
Lethality: Brucellosis has a very low mortality rate, less than 5% of untreated cases, with most deaths caused by endocarditis or meningitis.
