Where do mycobacterium tuberculosis come from?

Answer 1

Mycobacterium tuberculosis is primarily transmitted through the air when an infected person coughs, sneezes, or talks, releasing tiny droplets containing the bacteria. The bacteria originate from humans, as it is a pathogen that specifically affects humans and some primates. Environmental sources are not a significant factor in its transmission. Once inhaled, the bacteria can establish infection in the lungs and potentially spread to other parts of the body.
