In 2014, results of a new DNA study of a tuberculosis genome reconstructed from remains in southern Peru suggest that human tuberculosis is less than 6,000 years old. Even if researchers theorise that humans first acquired it in Africa about 5,000 years ago, [1] there is evidence that the first tuberculosis infection happened about 9,000 years ...
Roughly one-quarter of the world's population has been infected with M. tuberculosis, [6] with new infections occurring in about 1% of the population each year. [11] However, most infections with M. tuberculosis do not cause disease, [169] and 90–95% of infections remain asymptomatic. [87] In 2012, an estimated 8.6 million chronic cases were ...
Tuberculosis (TB) vaccines are vaccinations intended for the prevention of tuberculosis. Immunotherapy as a defence against TB was first proposed in 1890 by Robert Koch . [ 1 ] As of 2021, the only effective tuberculosis vaccine in common use is the Bacillus Calmette-Guérin (BCG) vaccine, first used on humans in 1921.

Trudeau's gravesite, St. Johns in the Wilderness Church, Paul Smiths, New York Edward Livingston Trudeau (October 5, 1848 – November 15, 1915) was an American physician who established the Adirondack Cottage Sanitarium at Saranac Lake for the treatment of tuberculosis.
Koch first discovered mycobacterium tuberculosis as the cause of tuberculosis in 1892 but the strains he studied were not preserved and it is unclear how related H37Rv may be to those strains. H37Rv has continued to be the strain of tuberculosis most used in laboratories, and was the first to have its complete genome published in 1998. [ 5 ]

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.
