Detailed explanation-1: -In the final decades of the 19th century, Koch conclusively established that a particular germ could cause a specific disease. He did this by experimentation with anthrax. Using a microscope, Koch examined the blood of cows that had died of anthrax. He observed rod-shaped bacteria and suspected they caused anthrax.

Detailed explanation-2: -Koch’s postulates are the following: The microorganism must be found in abundance in all organisms suffering from the disease, but should not be found in healthy organisms. The microorganism must be isolated from a diseased organism and grown in pure culture.

Detailed explanation-3: -On March 24, 1882, Robert Koch announced to the Berlin Physiological Society that he had discovered the cause of tuberculosis. Three weeks later, on April 10, he published an article entitled “The Etiology of Tuberculosis” (1).

Detailed explanation-4: -Although others had earlier determined that germs cause disease – notably Pasteur and Joseph Lister – Koch was the first to link a specific bacterium, in this case bacillus anthracis, to a specific disease.
