SOME DISEASES ARE NOT CAUSED by germs
Koch’s postulate
for organism to be the cause of disease it must…
- found in all cases of disease
- prepped and maintained in pure culture
- can produce original infection even after several generations of culture
- retrievable from inoculated animal, culture again
there’s always a way to prove that a germ is the cause of the disease
find it in common, grow it, infect another group, re-culture
Flemming
antibiotics
accidental discovery of penicillin… fungus produced something that destroyed bacteria
