The bacteria which causes Tuberculosis is called Mycobacterium Tuberculosis and it is spread through the air when a person with untreated pulmonary TB coughs or sneezes. Prolonged exposure to a person with untreated TB usually is necessary for infection to occur. The symptoms of TB include a low-grade fever, night sweats, fatigue, weight loss and a persistent cough. The main effect of TB affects the lungs (pulmonary TB). http://www.ebi.ac.uk/2can/genomes/bacteria/Mycobacterium_tuberculosis.html
