Tuberculosis Hiding in Bone Marrow Helps Deadly Bacteria Survive, Stanford University School of Medicine Study

Tuberculosis is a devastating disease that kills nearly 2 million people worldwide each year. Although antibiotics exist that can ameliorate the symptoms, the courses of therapy last for months and don't completely eradicate the disease, which frequently recurs years or decades after the initial treatment. Now, in a classic case of bench-to-bedside research, scientists at the Stanford University School of Medicine have discovered a possible reason for the disease's resistance: The ability of the tuberculosis bacteria to infiltrate and settle down in a particular class of stem cell in the bone marrow. By doing so, the bacteria take advantage of the body's own mechanisms of self-renewal.
