What did Koch discuss in Tuberculosis?

Koch argued in On Tuberculosis that "Mycobacterium tuberculosis is the root of tuberculosis and tuberculosis is a parasitic disease". It is pointed out that the most important thing to conquer tuberculosis is to study the sputum of tuberculosis patients, and the sputum of patients should be treated harmlessly with appropriate disinfection methods. In addition, the clothes and sheets used by tuberculosis patients should also be disinfected. This common sense, which now seems extremely common, attracted all the scientists attending the meeting at that time, and the venue was so quiet that people almost held their breath. For the first time in the history of the Berlin Physiology Association, there was no debate. On the night of the report, the news spread all over Berlin and then all over the world. Robert koch enjoys a world reputation. His photo was printed on a red handkerchief, and poems praising him were published in newspapers. People dubbed him "the father of Bacillus".
