what did Louis Pasteur first do?
found out the cause of disease
research discovered germs in the air caused liquids to go off

“Koch postulates”, methods that scientist need to satisfy before a particular bacteria can be excepted is causing a specific disease
eventually helped performance of public health to prove that pollution spread disease
what did Paul Ehrlich join?
Robert Kochs research team at “institute for infectious disease in berlin”

what happened in 1907?
paul ehrlich worked with over 600 chemical compounds that might kill the syphilis germ
what happened in 1909?
Sahaerhiro Hata (member of paul ehrlich’s team) discovered the compound that killed syphilis which was called salvarsan 606
what were “magic bullets”?
- paul ehrlich’s discovery, using synthetic dyes for studying microbes discovered presence of antibodies in blood
