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.
In 2008, evidence for tuberculosis infection was discovered in human remains from the Neolithic era dating from 9,000 years ago, in Atlit Yam, a settlement in the eastern Mediterranean. [7] This finding was confirmed by morphological and molecular methods; to date it is the oldest evidence of tuberculosis infection in humans.

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]
