Brucellosis Explained: Understanding Its Methods of Spread, Causes, and Remedies

In the United States, certain activities can increase the risk of coming into contact with the Brucella bacteria, such as travel to certain regions, occupations involving animals, and hunting wild animals. This article aims to shed light on the typical animals that carry Brucella bacteria in the U.S., the role they play in the transmission of the disease, and the implications for human health.

The primary domestic animals that serve as the natural reservoirs for brucellosis in the U.S. are cattle, bison, sheep, goats, swine, and dogs. Cattle and bison are primarily infected with Brucella abortus, a species that can potentially cause outbreaks. Sheep and goats commonly carry Brucella melitensis, a species that is not currently found in the U.S., but can be a common source for human cases, especially via the consumption of unpasteurized dairy products. Swine are mainly infected with Brucella suis, and Brucella canis can be found in domestic dogs.

Bison herds in the Rocky Mountain plains have recently become infected, potentially posing a transmission risk to domestic cattle. Brucellosis can enter the body through the eyes, mouth, or cuts in the skin, and the majority of brucellosis cases in humans in the U.S. are linked to consumption of unpasteurized goat milk products, occupational exposures such as in veterinarians, farmers, meat-packing workers, and others who have close contact with these animals or their products.

Dogs can carry Brucella bacteria in the U.S. and Canada, but there is no standard veterinary treatment. Complications of Brucellosis can include endocarditis, kidney damage, liver damage, problems with blood clotting, blood poisoning, encephalitis, stroke, and more. Treatment for Brucellosis typically involves a combination of antibiotics, doxycycline and rifampin, for 6-8 weeks.

In fewer than 10% of people who receive antibiotic treatment for Brucellosis, symptoms may reappear. A doctor may request a blood test called a serum agglutination test to diagnose Brucella infection. Anyone with symptoms of Brucellosis complications should also receive professional care.

It is important to note that Brucella bacteria can be contracted by consuming uncooked meat or unpasteurized dairy products. When to see a doctor includes if flu-like symptoms develop after coming into contact with wild animals, traveling abroad, drinking unpasteurized milk, or consuming unpasteurized dairy, or eating undercooked meat.

Brucella melitensis is carried by goats and sheep and is not currently found in the U.S., while Brucella ceti and pinnipedium are found in marine mammals and rarely infect people. Brucella abortus is found in some cows, wild elk, and bison in the U.S.

In conclusion, understanding the animals that carry Brucella bacteria in the U.S. and the potential risks they pose is crucial for public health. By being aware of the sources of the disease and taking precautions such as avoiding unpasteurized dairy products and properly cooking meat, individuals can significantly reduce their risk of contracting brucellosis. If symptoms do develop, seeking prompt medical attention is essential for effective treatment and management of the disease.
