Heinrich Hermann Robert Koch of Germany discovered anthrax bacteria, tuberculosis bacteria, and cholera bacteria. He also established a pure isolation method for bacteria that was not possible before. Koch’s postulates, the basic guidelines proposed by Koch to prove the pathogen of an infectious disease, are still used today to prove the causal relationship in infectious diseases. Koch’s Postulates (Quoted from Wikipedia) 1.  The microorganism must be found in abundance in all organisms […]
