In 1854, Louis Pasteur was appointed professor of chemistry at the University of Lille. He demonstrated that organism such as bacteria were responsible for souring wine, beer even milk. He then invented a process where bacteria could be removed by boiling and then cooling the liquid. Today the process is known as pasteurization. He completed the first test on April 20, 1862. In 1865, Pasteur helped to save the silk industry. He proved that microbes were attacking healthy silkworm eggs, causing the diseases, and the disease can be cured by eliminating the microbes. Pasteur first vaccine discovery was in 1879, with a disease called chicken pox. After accidentally exposing chicken to the attenuated form, he demonstrated that they became resistant to the actual virus. Pasteur went on to extend his germ theory to develop prototype of vaccine for diseases such as anthrax, cholera, TB, and smallpox. What is the main idea of the last paragraph?
