Robert Koch and his discoveries
He worked on Anthrax and in 1877, discovered typical Bacilli (Bacillus anthracis) with squarish ends in the blood of cattle that had died of anthrax.
Other bacteria discovered by Robert Koch are Mycobacterium tuberculosis (1882), Vibrio cholerae (1883), Staphylococcus (1878).
He also developed a technique for isolating bacteria on a culture plate.Robert Koch was the first person to grow bacteria on solid culture media. He employed gelatin as a solidifying agent.
When the news of Koch’s discovery spread rapidly from Germany to England and USA (via The Times, and The New York Times), Robert Koch became famous scientist. He is well known as “The Father of Bacteriology.”
Koch’s postulate provided guidelines to identify the causative agent of an infectious disease.
Koch’s postulates are:
- A specific organism can always be found in association with a given disease
- The organism can be isolated and grown in pure culture in the laboratory
- The pure culture will produce the disease when inoculated into a susceptible animal.
- It is possible to recover the organism in pure culture from the experimentally infected animal.
