As soon as I had found the tubercle bacillus, I found it also in the sputum of phthisical patients.

Understanding this quote
What it means
The moment Koch identified the tuberculosis bacterium in laboratory cultures, he immediately confirmed its presence in the actual lung secretions of patients suffering from consumption. This closed the logical loop: the same organism found in controlled study appeared in sick humans, proving the bacterium caused the disease rather than merely accompanying it.
Relevance to Robert Koch
Koch spent years developing staining techniques and culture methods specifically to isolate bacterial causes of disease. Finding the bacillus in patient sputum validated his entire methodological framework and fulfilled his own postulates, the four-step criteria he formulated to establish causation between a microbe and a specific illness.
The era
In the 1880s, tuberculosis killed one in seven Europeans. Miasma theory still competed with germ theory, and proving a specific microorganism caused a specific disease was revolutionary. Koch's 1882 announcement transformed medicine from symptomatic guesswork into targeted science, launching the bacteriological era and making infectious disease systematically conquerable.
