MT in the context of TB refers to Mycobacterium tuberculosis, the bacterium that causes tuberculosis.
Mycobacterium tuberculosis is the specific species of bacteria responsible for most cases of TB worldwide. The presence of this bacteria in the body can be detected through various tests, including the Mantoux test (also known as the tuberculin skin test or TST).
The Mantoux test involves injecting a small amount of tuberculin (a purified protein derivative of Mycobacterium tuberculosis) under the skin. A positive reaction, indicated by a raised, hardened area at the injection site, suggests that the individual has been exposed to Mycobacterium tuberculosis and has developed an immune response. Further testing is then necessary to determine if the individual has active TB disease or a latent TB infection.
In summary, when discussing TB, MT is an abbreviation for Mycobacterium tuberculosis, the causative agent of the disease.
