Spleen in tuberculosis. Gross specimen of a spleen from a tuberculosis (TB) patient. Large areas of tissue death (necrosis, pale) are seen. Tuberculosis is a disease caused by infection with Mycobacterium tuberculosis bacteria. These are usually inhaled in water drops in the air, and the primary infection is usually in the lungs. The infection can spread to the lymphatic system or to the blood, which can be fatal. TB causes coughing, chest pain, fever and sweating. It used to be a major killer disease, but it can now be treated with antibiotic drugs, and the BCG vaccine confers lifelong immunity.
