Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, [7] is a contagious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. [1] Tuberculosis generally affects the lungs , but it can also affect other parts of the body. [ 1 ]
No, tuberculosis is not caused by a virus. Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis, according to the U.S. Centers for Disease Control and ...
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [ 1 ] [ 2 ] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Since 1882, 24 March has been known as World Tuberculosis Day. [88] On 20 April 1882, Koch presented an article entitled Die Ätiologie der Tuberculose in which he demonstrated that Mycobacterium was the single cause of tuberculosis in all of its forms. [87] In 1890 Koch developed tuberculin, a purified protein derivative of the bacteria. [89]
This area is known as a “Ghon focus”. TB also gets to nearby hilar lymph nodes, either carried over by immune cells through the lymph or by direct extension of the Ghon focus infection and causes caseation there as well, and together, this caseating tissue and associated lymph node make up the characteristic “Ghon complex”.
Mycobacterium tuberculosis is a species of bacteria that causes tuberculosis, a respiratory infection. [13] Pseudomonas aeruginosa is a bacterium that can cause respiratory infections. It is frequently associated with cystic fibrosis and hospital-acquired infections. [14] Salmonella is a genus of bacteria, known to cause gastrointestinal ...
In this case a previously untreated person develops a new case of MDR-TB. This is known as primary MDR-TB, and is responsible for up to 75% of cases. [12] Acquired MDR-TB develops when a person with a non-resistant strain of TB is treated inadequately, resulting in the development of antibiotic resistance in the TB bacteria infecting them.
These bacteria typically cause foodborne illness. The bacterial disease tuberculosis, primarily caused by Mycobacterium tuberculosis, has one of the highest disease burdens, killing 1.6 million people in 2021, mostly in Africa and Southeast Asia. [16] Bacterial pneumonia is primarily caused by Streptococcus pneumoniae, Staphylococcus aureus ...
