Document Summary
Microbes are observed under a microscope with a single lense (stronger than hooke"s) Grinding lenses very simple but advanced microscope. Spontaneous generation is disproved for maggots (sealed meat) Cowpox vaccination prevents smallpox (if you"re exposed to cow pox you cant get cow pox (those who milked cows, mostly women, came in contact with cow pox milk maids ) Sanitation shows statistical correlation with mortality (crimean war) ~wash hands before going to next patient. Pasteurization ~ cut down on microbial levels in milk, al- cohol, wine, lactic acid, etc. Microbial fermentation pro- duces lactic acid or alcohol (pasteurization); disprove spontaneous generation but different from redi because oxygen did not have to be present. Microbes fail to appear spontaneously, even in the pres- ence of oxygen. Bacteria are a causative agent of anthrax (koch"s postu- lates figure 1. 18) (chain of infection) ~ proved that or- ganisms are in diseases.
