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 were formulated in the late nineteenth century as guidelines for establishing that microbes cause specific diseases. Because the rules were developed for living agents-particularly bacteria-their applicability to inanimate pathogens such as viruses and infectious proteins has been problematic.

Detailed explanation-3: -He discovered the dormant stage of the pathogen, anthrax spores, and thus unravelled the previously unexplained chain of infection and the bacterium’s strong resistance to environmental factors. In doing so, Robert Koch was the first to prove that a micro-organism was the cause of an infectious disease.

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.

Detailed explanation-5: -Robert Koch’s postulates, published in 1890, are a set of criteria that establish whether a particular organism is the cause of a particular disease.
