  • 3rd side (hint)
the study of organisms and agents too small to be seen with the naked eye
size of microorganisms
less than 1 mm
5 groups of microorganisms
first person to see microorganisms... year
Francesco Stelluti, 1625
the First person sure was STELLAR!
spontaneous generation
theory than living organisms could develop from nonliving matter
person who orginially disproved spontaneous generation
Francesco Redi
he was READY to defend it
how Redi originally disproved spontaneous generation
3 containers:
uncovered meat-- maggots on meat

meat covered by paper-- no maggots

meat covered by gauze-- maggots on gauze
person who OFFICIALLY discovered microorganisms
person who boiled mutton broths, stoppered flasks, and microorganisms grew
John Needham
as far as I'm concerned, this mutton experiment is useless and we didn't even NEED HIM
person who boiled flasks containing seeds and water, and microoganisms did not grow

reason thought to be that the micros were in the air in the flask and they died when the air was boiled
if you boil seeds, you SCALd them or SPILL them. a mix of the two, perhaps?
person who made air pass through a red-hot tube before it could enter the flask, no micros grew
Theodore Schwann
think of a swan passing through a red-hot tube (aww, now i'm sad)
people who made air pass through sterile wool before it could enter the flask, no micros grew
Schroeder and von Dusch
think of Vicky from Webster Schroeder passing through sterile wool and think of sterile wool in the von Dutch trucker hats
person who put the things that had been trapped on sterile wool onto a culture medium, micros grew.

person who first made the connection between microorganisms and disease, year, first connection

person who first designed antiseptic surgery using sterilization and phenol
Joseph Lister (my love!)
person who first made connection between bacteria and disease using mice and anthrax
Robert Koch
think about having anthrax on your cock
purpose of Koch's postulates
criteria for proving the causal relationship between a micro and a disease
koch's postulates (4)
1) the micro. must be present in every case of the disease but absent from healthy organisms

2) the suspected micro. must be isolated and grown in a pure culture

3) the same disease must be the result when the isolated micro. is introduced to a healthy host

4)the same micro. must be isolated from the diseased host
