Brucellosis In Humans: Causes, Symptoms, Diagnosis, Treatment

What Is Brucellosis In Humans?

Brucellosis is the name given to a bacterial infection, which basically is contracted from animals usually due to consumption of unpasteurized dairy products. In extremely rare cases, the bacteria can become airborne or spread through direct contact with infected animals. The symptoms observed in an individual with Brucellosis are fever, lethargy, and severe joint pains. This disease is successfully treated by using appropriate antibiotics. The treatment process lasts for months, although this disease may relapse. Brucellosis is pretty rare in the United States although it is present in significant numbers elsewhere across the globe. Avoiding unpasteurized dairy products and wearing protective clothing while near animals can prevent an individual from contracting Brucellosis.

What Are The Causes Of Brucellosis In Humans?

Some Of The Causes Of Brucellosis Are:

Raw Dairy Products: The bacterium which causes Brucellosis is called as Brucella and it can spread to humans through unpasteurized milk, ice cream, cheese, or other dairy products. It can also spread from undercooked meat of an infected animal.

Inhalation: Brucella becomes airborne easily and people who are involved with animals gets this disease easily like farmers, laboratory technicians etc.

Direct Contact: This bacterium can also infect the humans through direct contact with an infected animal through cuts and bruises. Normal touching or playing with the animal does not cause this disease; hence, Brucellosis is rarely caused from pets, although individuals with a compromised immune system should stay away from animals who may be carriers of this bacterium even if they are pets.

How Is Brucellosis In Humans Diagnosed?

To confirm a diagnosis of Brucellosis, the treating physician will collect blood or bone marrow sample to analyze to look at the antibodies for Brucella which if present will confirm the diagnosis of Brucellosis. Additionally, the following tests may also be performed for confirmation:

X-rays: This will reveal changes in bones or joints.

CT scan/MRI: This will determine the presence of formation of any abscess in the brain due to Brucellosis.

Cerebrospinal Fluid Analysis: This will check for presence of any infection in the brain or the spinal cord like encephalitis etc. due to Brucellosis.
