Brucellosis is a bacterial infection that can affect both humans and animals. It’s caused by various species of the Brucella bacteria. In this article, we’ll provide you with a comprehensive overview of Brucellosis, including its types, causes, symptoms, diagnostic tests, treatments, and medications. We aim to present this information in a simple and easy-to-understand language to improve accessibility and visibility on search engines.
Brucellosis Types:
- Classical Brucellosis: This is the most common form of the disease and is caused by the Brucella melitensis bacteria.
- Bovine Brucellosis: Caused by Brucella abortus, this type mainly affects cattle and can also be transmitted to humans.
- Swine Brucellosis: This type is caused by Brucella suis and is primarily associated with swine, but humans can also be infected.
- Canine Brucellosis: Brucella canis is responsible for this type, affecting dogs and sometimes spreading to humans.
- Marine Mammal Brucellosis: Marine mammals can carry Brucella ceti and Brucella pinnipedialis, and exposure to these animals can transmit the disease to humans.
- Atypical Brucellosis: This category includes rare forms of Brucellosis, such as Brucella ovis in sheep and Brucella neotomae in desert woodrats.
- Occupational Brucellosis: Certain professions, like veterinarians and slaughterhouse workers, are at a higher risk of contracting the disease due to their close contact with infected animals.
- Chronic Brucellosis: Some individuals may develop long-lasting symptoms, turning the acute infection into a chronic condition.
- Reservoir-Related Brucellosis: In regions with specific animal reservoirs, like Brucella suis in wild boars, the disease can be prevalent.
- Travel-Related Brucellosis: Travelers to areas with high Brucellosis prevalence may become infected, highlighting the importance of preventive measures.
Brucellosis Causes
- Consuming Unpasteurized Dairy Products: Drinking raw milk or eating unpasteurized cheese can expose you to the Brucella bacteria.
- Handling Infected Animals: Close contact with infected livestock, such as cows, goats, or pigs, can lead to transmission.
- Occupational Exposure: People working in agriculture, veterinary services, or meat processing are at a higher risk due to their contact with infected animals.
- Consuming Undercooked Meat: Eating undercooked meat from infected animals can introduce the bacteria into your system.
- Inhaling Contaminated Air: In rare cases, inhaling airborne particles contaminated with Brucella can lead to infection.
- Contaminated Water: Drinking water contaminated with the bacteria can cause infection.
- Handling Animal Placentas: Disposing of infected animal placentas without proper protection can result in transmission.
- Contact with Aborted Animal Fetuses: Handling fetuses from infected animals can expose you to the bacteria.
- Tick Bites: Some ticks can carry Brucella and transmit the disease when they bite humans.
- Unhygienic Farm Practices: Poor sanitation on farms can facilitate the spread of Brucella.
- Inadequate Personal Hygiene: Failing to wash hands after handling animals or animal products can lead to infection.
- Drinking Infected Urine: In very rare cases, drinking urine from infected animals can transmit the bacteria.
- Transfusion of Infected Blood: Transfusion of contaminated blood can introduce Brucella into the bloodstream.
- Sexual Contact: Sexual transmission of the bacteria is possible, especially in cases of Brucella canis.
- Contaminated Instruments: Using medical or veterinary instruments not properly sterilized can lead to infection.
- Ingesting Bone Marrow: Consuming bone marrow from infected animals carries a risk of infection.
- Oral Vaccination in Animals: Certain oral vaccines used in livestock can shed Brucella and potentially infect humans.
- Visiting Infected Zoos: Close contact with infected animals in zoos can be a source of transmission.
- Importing Infected Animals: Importing animals carrying Brucella can introduce the disease to new regions.
- Inadequate Pest Control: Poor control of pests like rodents, which can carry Brucella, can increase the risk of infection.

- Skin Rashes: Rashes and skin discoloration are uncommon but possible symptoms.
- Eye Inflammation: Redness, pain, and sensitivity to light can affect the eyes.
- Mental Health Changes: Brucellosis can lead to mood swings, depression, and anxiety in some cases.
Brucellosis Diagnostic Tests
- Blood Cultures: A sample of your blood is cultured to detect the presence of Brucella bacteria.
- Serological Tests: Blood tests can identify specific antibodies produced in response to the infection.
- Bone Marrow Culture: In severe cases, bone marrow may be cultured to detect the bacteria.
- PCR Test: Polymerase chain reaction (PCR) can amplify and detect the DNA of Brucella.
- ELISA Test: Enzyme-Linked Immunosorbent Assay (ELISA) is used to detect antibodies in the blood.
- Rose Bengal Test: This agglutination test helps detect antibodies quickly.
- Wright Test: A serum agglutination test used to detect Brucellosis antibodies.
- Lymph Node Biopsy: In some cases, a sample of an enlarged lymph node may be examined for infection.
- Ultrasound: Imaging may reveal enlarged organs, like the spleen or liver.
- CT or MRI Scans: These scans can provide detailed images of affected organs.
- X-Rays: Chest X-rays can help assess lung involvement.
- Cerebrospinal Fluid Analysis: If neurological symptoms are present, analyzing cerebrospinal fluid may be necessary.
