There are several infectious species of Brucella, but B. suis is the only species in Australia that can cause human disease. Brucellosis has been eradicated from Australian cattle herds, but it still present in feral pigs in northern Australia and is a risk to those who hunt and/or butcher feral pigs.
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.
Brucellosis is a zoonotic disease caused by the intracellular bacteria, Brucella species. There are several types of Brucella bacteria, but Brucella suis is the only species in Australia that can cause human disease. It is transmitted to humans from infected animals.
*Three types of the bacteria that cause brucellosis – Brucella abortus, Brucella melitensis and Brucella suis – are designated as select agents. This means that they have the potential to be developed as bioterrorism agents due to their ability to undergo aerosolization.
Of the 4 Brucella species known to cause disease in humans (B abortus, B melitensis, B canis, B suis), B melitensis is thought to be the most virulent and causes the most severe and acute cases of brucellosis; it is also the most prevalent worldwide.
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.
Brucella species differ markedly in their capacity to cause invasive human disease. Brucella melitensis is the most pathogenic; B abortus is associated with less frequent infection and a greater proportion of subclinical cases. The virulence of B suis strains for humans varies but is generally intermediate.
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 is a disease caused by the bacteria of the genus Brucella. These bacteria are primarily passed among animals, and they cause disease in many different vertebrates. Various Brucella species affect sheep, goats, cattle, deer, elk, pigs, dogs, and several other animals.
Surveillance and reporting. Brucellosis is a nationally notifiable disease. We monitor cases through the National Notifiable Diseases Surveillance System. For more on brucellosis in Australia, you can search Communicable Diseases Intelligence .
Surra is currently absent from Australia, PNG and West Papua.
suis biovars have obviously limited potential to infect humans. The reason why the B. ovis is not zoonotic in opposite to the rest of Brucella species is attributed to the fact that the genome of B.
Live-Attenuated Vaccines. In recent decades, the most effective way to control brucellosis has been to vaccinate animals. Although vaccination of individuals living in brucellosis endemic areas, veterinarians, livestock, and laboratory personnel is essential, human vaccines have not yet been developed (9).
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.
Bovine tuberculosis (BTB) is caused by M. bovis, a Mycobacterium closely related to the human pathogen M. tuberculosis, both belonging to the Mycobacteria Tuberculosis Complex (MTC) [1]. Brucellosis is a bacterial infectious disease caused by Brucella spp, with B.
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.
Human cases of brucellosis are uncommon, with only 100 to 200 cases a year reported in the U.S. Although brucellosis can make you very sick, it is rarely fatal.
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.
Consumption of raw milk containing Brucella can cause brucellosis. Most cases of brucellosis associated with raw milk are caused by a strain called Brucella melitensis or Brucella abortus in people who traveled to countries where these strains are common and drank contaminated cow, sheep or goat milk.
Eating undercooked meat or consuming unpasteurized/raw dairy products. The most common way to be infected is by eating or drinking unpasteurized/raw dairy products. When sheep, goats, cows, or camels are infected, their milk becomes contaminated with the bacteria.
abortus are considered the most important species that cause illness in humans and domestic animals in many countries throughout the world. Three biovars of B. melitensis mainly infect sheep and goats, while the preferred hosts of seven biovars of B. abortus are cattle and buffaloes (3).
Generally, the antibiotics doxycycline and rifampin are recommended in combination for a minimum of 6-8 weeks.
Occupational groups at high risk of brucellosis include butchers, livestock farmers/breeders, milkers, veterinarians, inseminators, laboratory workers as well as individuals associated with packing and selling dairy products and raw meat (6, 10, 11, 15, 19).
