+ History of Microbiology

+ Old world views Disease caused by: Sins Wrong doings Associations with “sick” people Minorities Cured by: Religious leaders- exorcism, purging “Doctors”- used blood letting

+ Common practices of Middle ages Feces was dumped in the alleys Dead bodies were left to rot Food was prepared in filthy kitchens Hand washing was not considered necessary Unsterile equipment used for surgeries Ex: Typhoid Mary-healthy carrier of Typhoid Cook-spread disease to about 50 people (1900’s)

+ Start of Microbiology Antonie Van Leeuwenhoek perfected the microscope First saw living organisms from his saliva Called them animacules Presented the idea that we now understand as microorganisms 1676 Father of Microbiology

+ Louis Pasteur Supported the germ theory of disease Created the rabies vaccine Discovered pasteurization- killing bacteria in products like milk 1860

+ Robert Koch Koch’s postulates- how bacteria cause disease Identified some of the most harmful bacteria Tuberculosis Anthrax Cholera

+ Joseph Lister Surgeon 1 st to use sterile technique Success rate of surgeries increased as a result

+ Modern advances Sterile surgery is required Vaccines and antibiotics are readily available Most harmful bacteria have been identified Still many risks of a superbug
