Bovine Tuberculosis (TB) is a chronic bacterial disease of humans and animals, and is present in many species of animal including cattle, pigs and sheep. The disease is mainly spread between animals via inhalation or respiratory fluids, and the disease causes the formation of multiple masses called tubercles, particularly in the lung and lymph nodes. Many other organs can be affected by the tubercles, which are usually dry and firm, and have a tough fibrous capsule containing a soft, thick, pus like fluid inside. Tubercles can range in size from being too small to see without a microscope, to involving a large part of an organ.  Link to pictures
