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.
Löwenstein–Jensen medium, more commonly known as LJ medium, is a growth medium [1] specially used for culture of Mycobacterium species, notably Mycobacterium tuberculosis. When grown on LJ medium, M. tuberculosis appears as brown, granular colonies (sometimes called "buff, rough and tough").
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 ...
Mycobacteria Growth Indicator Tube (MGIT) is intended for the culture, detection and recovery of mycobacteria. The MGIT Mycobacteria Growth Indicator Tube contains 7 mL of modified Middlebrook 7H9 Broth base.
Mycobacterium bovis causes tuberculosis in cattle. Since tuberculosis can be spread to humans, milk is pasteurized to kill any of the bacteria. [5] Mycobacterium tuberculosis that causes tuberculosis (TB) in humans is an airborne bacterium that typically infects the human lungs. [6] [7] Testing for TB includes blood testing, skin tests, and ...
The poet John Keats, here depicted by William Hilton c. 1822, died of tuberculosis aged 25.. Tuberculosis, known variously as consumption, phthisis, and the great white plague, was long thought to be associated with poetic and artistic qualities in its sufferers, and was also known as "the romantic disease".

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 ( M. leprae ) in humans.
Middlebrook 7H9 broth supports the growth of mycobacterial species when supplemented with nutrients such as glycerol, oleic acid, albumin, and dextrose, except for Mycobacterium bovis, which is inhibited by glycerol. Cultures should be read within 5–7 days after inoculation and once a week thereafter for up to 8 weeks.
