M. tuberculosis bacteria are the sole cause of tuberculosis

Tuberculosis is an infectious disease that attacks the main human respiratory tract, the lung. However, it can also spread to other parts of the body, such as the kidneys, spine, and brain if left untreated. The cause of TB is type bacteriaMycobacterium tuberculosis.

According to the University of Iowa Environmental Health and Safety, millions of people have bacteria that cause tuberculosis in their bodies, but not all of them will fall ill after exposure to bacteria. There are two TB conditions that you need to understand, namely:

  • Latent tuberculosis, which is bacteria in the body, but not active. This condition does not cause symptoms and is not contagious, but can be active at any time.
  • Active tuberculosis, which is bacteria in the body can cause symptoms and can be transmitted to other people.

About 5 to 10 percent of bacteria that will actually cause active TB and will transmit it to other people. The spread of the most active bacteria will occur when the lungs have begun to be damaged by the bacteria itself or damaged by other diseases, such as chronic obstructive pulmonary disease (COPD).

However, bacteria can attack the lungs easily in people with low immune systems, especially in patients with HIV, malnutrition, diabetes, and high risk of active smokers.

bacteria is

BacteriaMycobacterium tuberculosisspread through the air. Just like flu, bacteria will move from people infected with tuberculosis to healthy people through droplets of saliva, which usually occurs when coughing, sneezing, spitting, even talking.

The bacteria that are carried along with these saliva droplets can be inhaled and deposited on the surface of the pulmonary alveoli. Alveoli are small bubbles in the lungs where oxygen is exchanged with carbon dioxide.

Active bacteria can multiply causing damage to the alveoli. Without treatment, bacteria can be carried along with the blood and attack the kidneys, bone marrow, back, and brain which will eventually cause death.
