Tuberculosis (TB) is a deadly infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis (MTB) in humans. Worldwide, the incidence of TB is about eight million and about three million people die each year. TB usually attacks the lungs but can also affect other parts of the body. It is spread through the air, when people who have the disease cough, sneeze, or spit. Of the members of MTB complex, M. tuberculosis and M. africanum are pathogenic in humans only. M. bovis, M. microti and M. pinnipedii, though etiologic agents of tuberculosis in cows, voles, and seals respectively, are known to infect TB in humans as well.
