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 ]
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 .
The tubercle bacteria many enter the abdomen via the consumption of infected milk. Those with existing pulmonary tuberculosis can have abdominal tuberculosis through the ingestion of infected sputum. [2] When the gastrointestinal tract is infected with the bacteria, epitheloid tubercles are formed in the lymphoid tissue of the submucosal layer.
Mycobacterium is a genus of over 190 species in the phylum Actinomycetota, assigned its own family, Mycobacteriaceae.This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis (M. tuberculosis) and leprosy in humans.
Mycobacterium bovis is a slow-growing (16- to 20-hour generation time) aerobic bacterium and the causative agent of tuberculosis in cattle (known as bovine TB).It is related to Mycobacterium tuberculosis, the bacterium which causes tuberculosis in humans.
This bacteria typically causes foodborne illness. Although the vast majority of bacteria are harmless or beneficial to one's body, a few pathogenic bacteria can cause infectious diseases . The most common bacterial disease is tuberculosis , caused by the bacterium Mycobacterium tuberculosis , which affects about 2 million people mostly in sub ...
The Mycobacterium tuberculosis complex (MTC or MTBC) is a genetically related group of Mycobacterium species that can cause tuberculosis in humans or other animals. It includes: Mycobacterium tuberculosis; Mycobacterium africanum; Mycobacterium orygis [1] Mycobacterium bovis and the Bacillus Calmette–Guérin strain; Mycobacterium microti ...
Multidrug-resistant tuberculosis (MDR-TB) is a form of tuberculosis (TB) infection caused by bacteria that are resistant to treatment with at least two of the most powerful first-line anti-TB medications (drugs): isoniazid and rifampicin.
