Brucellosis is an infectious disease caused by Brucella bacteria, which can be transmitted through various routes, including contact with infected animals (such as cattle, sheep, goats, and pigs), consumption of unpasteurized dairy products, or direct contact with bodily fluids like semen or abortions. The infection typically enters the body through mucous membranes or breaks in the skin and can also be spread through aerosols. Once inside the host, Brucella bacteria multiply in macrophages, leading to a systemic infection that can affect multiple organs, particularly the liver, spleen, and lymph nodes. Symptoms can range from mild, including fever, fatigue, and muscle pain, to severe and life-threatening conditions like septic arthritis, pneumonia, and disseminated disease, especially in immunocompromised individuals. Treatment usually involves antibiotics, but early diagnosis and intervention are crucial for preventing complications and reducing the risk of transmission.
