In which year did Robert Koch prove that specific bacteria caused specific diseases?

Robert Koch proved that specific bacteria caused specific diseases in 1882 through his discovery of the bacterium responsible for tuberculosis. This was a significant milestone in the field of microbiology and medicine, as it established the germ theory of disease, which asserts that microorganisms are the cause of many diseases. Koch's work not only identified the pathogens involved but also laid the groundwork for further research into infectious diseases, leading to better understanding, prevention, and treatment methods. His development of Koch's postulates provided a systematic method to link specific pathogens to specific diseases, fundamentally transforming medical science and public health approaches in the years that followed.
