Knowledge about disease
Louis Pasteur: discovered that germs cause disease by using a swan-necked flask. Before his discovery, doctors are aware that bacteria existed, but they believed it was the disease that cause the bacteria (the so-called theory of 'spontaneous generation') rather then the other way round.
Other spin-offs of Pasteur's discovery was the pasteurisation of milk, which prevented it from the air.
PASTEURISATION= a process in which a liquid s heated to a specific temperature, in order to kill microorganisms in the liquid that could be damaging to health.
Robert Koch: discovered how to stain and grow bacteria in a Petri dish (named after his assistant Julius Petri). He was able to find which bacteria caused which diseases:
- septicaemia 1878
- TB 1882
- cholera 1883
In the same period other bacteria were discovered, including those that caused:
- typhoid 1880
- pneumonia 1882
- cholera 1883
Causes of improvements in physiology and pathology
The Industrial Revolution / inventions
- there was a general atmosphere of scientific research and advance.
- Louis Pasteur's first commission was to find a cure for sour wine, which set hime off on his revolutionary course
- Joseph Jackson Lister invented the multi-lens microscope, which allowed doctors to see very tiny things accurately
- Carl Ludwig invented the kymograph, which allowed more accurate measurement of the pulse
