The driver asked, "Why was I pulled over when I wasn't the only one speeding."
The police replied, "Have you ever been fishing?"
The man then said, "yes".
"Have you ever caught all the fish?" asked the policeman.
TuberculosisIn 1882, German scientist Robert Koch declared to the Berlin Physiological Society that he had discovered the bacillus responsible for tuberculosis. The audience was spellbound. Within three weeks, on 10 Apr 1882, he published*The Etiology of Tuberculosis. He published an expanded version in 1884, in a second paper under the same title, which presented “Koch's postulates,” which now have been generalized and fundamental in the study of a cause of an infectious disease. Namely, he had found the bacillus present in all cases of the disease, had isolated and cultured the microorganism, with which he had caused the disease by using it to inoculate and infect a new host, and identified the same microorganism from the diseased host. Koch was awarded the Nobel Prize in medicine in 1905.«*Koch R. Die Atiologic der Tuberkulose, Berliner Klinische Wochenschrift 1882; 15:221-30.
