Detailed explanation-1: -Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick.
Detailed explanation-2: -Pneumonia is a common lung infection caused by bacteria, a virus or fungi. It often spreads via coughing, sneezing, touching or even breathing, and those who don’t have symptoms can also spread it.
Detailed explanation-3: -When a person breathes in TB bacteria, the bacteria can settle in the lungs and begin to grow. From there, they can move through the blood to other parts of the body, such as the kidney, spine, and brain. TB disease in the lungs or throat can be infectious. This means that the bacteria can spread to other people.
