what is tuberculosis?

Tuberculosis is an infectious disease caused by a bacterium called Mycobacterium tuberculosis or Mycobacterium tuberculosis (BK), named after the doctor who discovered it in 1882, Robert Koch.


Koch's bacillus or BK is the bacterium that causes tuberculosis infects the respiratory predilection: pulmonary tuberculosis represents a little more than 70% of TB cases.
The disease can affect all organs. The main locations are described extra-pulmonary lymph nodes, urogenital, musculoskeletal and cerebrospinal meningitis.
This infection is considered a public health priority throughout the world, especially as the number of cases resistant to treatment increases concern.
Depending on the number of drugs that resists BK, is called multidrug resistance (resistance to at least two major antituberculous antibiotics) or highly resistant (resistant to virtually all TB). 
World Day of fight against tuberculosis, held on 24 March each year, is an opportunity to take stock of the situation of the disease in the world and progress in its management.
