medical discoveries

The bacillus-causing tuberculosis, Mycobacterium tuberculosis, was identified and described on March 24, 1882 by Robert Koch (Germany). He received the Nobel Prize in physiology or medicine in 1905 for this discovery. Koch did not believe that bovine (cattle) and human tuberculosis were similar, which held back the recognition of infected milk as a source of infection. Later, this source was eliminated by the pasteurization process. Koch announced a glycerine extract of the tubercle bacilli as a "remedy" for tuberculosis in 1890, calling it 'tuberculin'. It was not effective, but was later adapted by von Pirquet in a test for pre-symptomatic tuberculosis.
